Getting Started
Communications
Setup
The AXIMA Software will establish serial communications when you
select either the Upload, Download or OnLine commands from the
File menu (or by selecting the Upload, Download or Online icons from
the tool bar). In a multi-drop configuration you will be prompted for
the controller address unless you check the Prompt For Controller
Address option in the Communications tab of the Preferences dialog
box.
Upload
The Upload option (from the File menu or the Upload icon) allows you
to upload an Application from the controller. This process may take
up to three minutes (at 19.2 Kbaud). A window is displayed showing
the percent complete and provide the ability to cancel the upload. The
new Application window is placed on top of any previous
Applications. The new Application is created with the data from the
controller.
An important feature of the AXIMA Software is the ability to upload
(restore) the entire Application from the controller. This means that
File,Upload and File,Open provide identical functionality.
File,Upload restores all instructions, comments, names, programs,
coordinate systems with no exceptions.
Download
The Download option (from the File menu or the Download icon)
transmits the current application from your PC to the AXIMA
controller. This process may take up to three minutes (at 19.2
Kbaud).
5
NOTE:
It is important that you remember that when creating and
editing Applications off-line, the changes you make do
not occur in the AXIMA controller until they are downloaded.

Version Download Message
After communications with the AXIMA controller has been
established, the AXIMA Software displays a message box (shown
below) if an application already exists in the AXIMA controller’s
memory. The purpose of this message is to provide data about the
application currently in memory and to provide you with the option
to cancel the download before the new Application is downloaded
overwriting the Application currently in the AXIMA controller.

OnLine
The OnLine option (from the File menu) allows you to go “online”
with the AXIMA controller. This process may take up to 30 seconds
(at 19.2 Kbaud).
When the Online mode is initially selected, the AXIMA Software
uploads all application details except the instructions contained
within the programs. As programs are selected in Online mode each
program is uploaded as needed.
When in the Online mode the software operates differently in
important ways. First, the OK buttons for Application, Coordinate
System, Axis and Programs have been changed to Send. However,
these buttons are grayed since the online mode operates in read-only.
OnLine mode also provides the following features: Diagnostics,
Program Control, EEPROM Utilities and Tuning.

AXIMA Reference ManWorking with
Applications
Creating or Opening Applications
Applications are created by selecting either New, Open, Upload or
OnLine from the File menu.
•
The New option is used to create a completely new Application.
•
The Open option is used to open an existing Application from
your hard drive.
•
The Upload option will upload the Application currently in the
AXIMA controller to your PC.
•
The Online option will upload and download sections of the
Application as you move between dialog boxes.
Viewing or Editing Applications
An important and useful feature of the AXIMA Software is the
support for editing and viewing of multiple Applications
simultaneously. For example, it is possible to edit two Applications
off-line (from your PC's disk) and also have an online Application
open. All combinations are supported with the single exception that
only one online Application per serial port is allowed to be open at
any one time.
Editing an Application is done from the "Edit Window" within the
AXIMA Software. The edit window is divided into two halves, the left
half is referred to as the hierarchy view and a right half is referred to
as the details view. The hierarchy view displays your Application in
a hierarchical fashion with the Application name at the top left. The

Hierarchy View
Figure 4
Detail View
AXIMA Software’s Edit Window
The right half displays a detailed view of the item highlighted in the
hierarchy view. Double clicking a line on the hierarchy view will
expand or contract that line’s sub-parts. Double clicking a line on the
details view will bring up the appropriate dialog box to edit that piece
of information with the focus on the correct field within the dialog box
for easy modification.
Below is the recommended procedure for creating an Application.
This procedure assumes that the Application is a new application offline. If the Application is not new, subsets of this procedure are used.
This procedure illustrates the steps involved and the navigation
between the various dialog boxes.
10
Application Creation Procedure
1. Select New from the File menu. A new application window is
displayed
2. Double click on Application Name in the details view side. The
Application dialog box will appear where you name your
Application and add comments as needed. We recommend that
the first word of the Application name is the file name.
3. With Controller Options highlighted in the hierarchy view,
choose Add Coordinate System from the Edit menu or use the
Add Coordinate System icon from the toolbar. Add the
Coordinate Systems needed for the application and give each
Coordinate System a unique name.
4. For each Coordinate System, add the axes, give each axis a
unique name and select the DAC and encoder for each axis.
5. For each axis, select the drive type, motor size, velocity, torque,
or pulseloop control. This allows defaults to be used for the axis
servo loop options
6. Review the servo loop options, using the Defaults button to load
gains and add filters (if necessary). Later you will be able to
adjust these values with the Tuning Procedure.
7. Edit the axis limits in the Axis Limits dialog box.
8. Create the Motion and PLC Programs for all of the Coordinate
Systems.
9. Save the Application to disk.
All dialog boxes used to create and/or edit an Application (including
creating Motion, PLC and Auxiliary Programs) are described on the
following pages. The order of the dialog boxes follows the Application
setup procedure above.
11
Dialog Boxes
The AXIMA Software uses dialog boxes as a method of gathering
information. Most of the dialog boxes are “modal”, that is, you can not
switch between dialog boxes until you finish (OK/Cancel) the
currently displayed dialog box.
Each dialog box contains a series of fields you can move between by
pressing the Tab key. These fields allow you to enter information in
a number of ways (e.g. select from lists, press buttons, enter test in
boxes, check boxes, etc.). Some fields on these dialog boxes will not be
needed in certain situations, these fields are “grayed”.
Application
To display this dialog box, highlight the Application name (top line
on the hierarchy view side) then double click any line on the details
view side (right side). This dialog box allows you to do the following:
12
•
Name the Application using up to 20 alpha-numeric characters.
•
View Coordinate Systems and Auxiliary Programs.
•
Enter Comments that describe the Application in detail.
•
Set Application options.

Application Dialog Box
Options Button
Clicking on this button displays the Applications Options dialog box
allowing you to adjust the Servo Loop Update Interval (SUI). The
units are in microseconds.
Figure 6
Application Options Dialog Box
The position loop for all axes will be updated within the SUI time you
enter here. The smaller the setting, the quicker the servo loop will be
updated. However, the servo update processing time takes away from
Motion or Auxiliary Program instruction execution time.
One PLC (Programmable Logical Controller) program is executed per
interval, therefore, this setting will effect the PLC program
performance. Also, the Input/Output (I/O) is updated after all PLC
programs are executed, this setting will affect the I/O update rate.
13
The goal is to balance DSP (Digital Signal Processor) performance to
provide as much processing time for all Motion, Auxiliary and PLC
Programs while updating the servo loops adequately.
The table below shows general guidelines for the Servo Loop Update
Interval verses the number of axes in your Application.

Reconfiguration
When you select the different AXIMA controller types the AXIMA
Software will try to reconfigure the Application for that particular
16
controller type. You will be informed about conflicts and changes that
need to be completed before the configuration can be completed.
!
WARNING
Changing the configuration of a AXIMA to an AXIMA 2000/4000 will not
update the PLS array and mask automatically. Change these under the
PLS Definition Instruction or reconfiguration options.
Coordinate System
The Coordinate System dialog box appears when you select "Add
Coordinate System" from the Edit menu or by double clicking on the
Coordinate System name in the details view of the applications
window. The Coordinate System dialog box allows you to add, view or
make changes to a Coordinate System in the Application that is
currently open. The dialog box allows you to do the following:

Acceleration
The Acceleration time set here, is the initial value used by the motion
program.
Deceleration
The Deceleration time set here is the initial value used by the motion
program.
S-Curve
The S-Curve parameter is used to reduce the tendency of the motor
to jerk when accelerating and decelerating by controlling the slope of
the acceleration versus time profile.
If this values is zero (Ø), the acceleration profile is rectangular.
Otherwise, the acceleration profile is trapezoidal, clipped at the top
or bottom by the current acceleration or deceleration. The best value
for S-Curve is four to eight times the acceleration value. A zero value
disables this feature.
18
The following figure illustrates the result of the S-Curve feature on a
normal move.
Figure 11 S-Curve Velocity Profile
External Time Button
The External Time Base Setup dialog box appears when you select
the External Time button from the Coordinate System dialog box.
This option sets up the external time base parameters used when
external time base velocity is selected in a Motion Program. When an
external time source is used to determine the velocity of a move
instead of the internal clock, the move is based on the frequency of
encoder pulses rather than seconds or minutes.
Figure 12 External Time Base Setup Dialog Box
Master Units
Use this parameter to specify user units that will be associated with
this coordinate system’s external encoder such as Revs, Feet, Inches,
mm, etc.
19
Master Counts/Units
This parameter defines the number of encoder counts per Master
Unit. For example, if you entered “inches” for master units, and on
revolution of the encoder equals four inches of travel, then the Master
Counts/Units would be 4096/4 = 1024.
Time Source
This parameter allows you to select the encoder which will be the
external time source for this coordinate system when external time
base velocities are used.
Signal
This options in this list box determine how the encoder pulses will be
will be acted on. There are five options to choose from: Comp +,
Comp -, Plus, Minus, and Plus and Minus.
Comp +
In this mode, The follower axes will only respond to master encoder
pulses when the master encoder is running in the CW direction. The
AXIMA counts the pulses received in the CCW direction and ignores
that same number of CW pulses before motion resumes in the
follower axes.
Comp In this mode, The follower axes will only respond to master encoder
pulses when the master encoder is running in the CCW direction.
The AXIMA counts the pulses received in the CW direction and
ignores that same number of CCW pulses before motion resumes in
the follower axes.
Plus
In this mode, motion will only occur in the follower axes when master
encoder pulses are received in the CW direction. Follower axes will
not respond to encoder pulses in the CCW direction.
20
Minus
In this mode, motion will only occur in the follower axes when master
encoder pulses are received in the CCW direction. Follower axes will
not respond to encoder pulses in the CW direction.
Plus And Minus
In this mode, motion will occur in the follower axes, in the
commanded direction, whenever master encoder pulses are received,
regardless of the direction (either CW or CCW).
Axis Parameters
The Axis Parameters dialog box below allows you to define each axis.
Each axis has a command output (DAC) and an encoder input (ENC).
Figure 13 Axis Parameters Dialog Box
Axis Name
You can enter up to 20 alpha-numeric characters for the name of each
axis.
21
Connector Number
The number box is where you specify which axis connector (located
on the front panel of the AXIMA) this axis will interface with.
Servo Control
The servo control section describes drive controller and motor
combination is used with this axis. For example, If you are using an
EMERSON Motion Control MX-280 amp with a BL-316 motor, select
the appropriate drive and motor models in the Drive and Motor
boxes. If you are not using an EMERSON drive or motor, select
unspecified.
Loop Control
The loop control options are used to select whether DAC signal is
connected to the drives velocity or torque loop input. This selection
will cause different servo defaults to be loaded in the axis servo
options dialog box.
Polarity
This parameter allows you to change the polarity of the polarity of
the axis which controls the direction of the motor and the encoder.
Units
You can specify individual user units to be associated with each axis,
this allows all motion to be defined in terms of the user units. The CW
Direction and CCW Direction boxes allow you to enter descriptive
names for what it means to turn the motor CW and CCW. User units
name are used as labels in various programming instructions.
Encoder Counts/Unit
Encoder counts/unit is the number of encoder pulses per user unit
times the multiplier. For example, if your encoder produced 1024
pulses/revolution, and user units are revolutions, one revolution of
the encoder is equated to one user unit of motion (or one revolution)
with a multiplier of 4 the Encoder Counts/Unit would be 4096.
22
Rotary Length
The Rotary Length function is only available when A4 or later
firmware is used.
This option sets the rotary axis length used for the shortest distance
calculations. The default rotary length is 0.0 for all axes, disabling
shortest distance moves.
If the rotary length of an axis is non-zero, a MOD function is done on
absolute moves and the result is run through a shortest distance
calculation. The resulting move will never be longer than half the
rotary axis length. Incremental moves are not affected by the rotary
axis length.
This option actually converts absolute moves into incremental moves
that are up to plus or minus half the rotary length. Profiler positions
are normally generated that lie outside of the rotary length
boundaries. The Normalize instruction can be used to return the
current position to within the bounds of the rotary length.
Options Button
The More Axis Parameters dialog box below appears when you select
the Options button from the Axis Parameters dialog box.
Figure 14 More Axis Parameters Dialog Box
23
Command
Gain
The value you enter here is used to calibrate the analog output signal
(i.e. gain adjust will linearly adjust the output).
Offset
The Offset box allows you to apply a correction to the analog output
command which otherwise may cause slow rotation of the motor with
a zero command output.
Feedback Source
Encoder Number
The number box is where you specify which axis connector (located
on the front panel of the AXIMA) this axis will interface with.
Typically, this is the same connector as the command connector
number.
Encoder Multiplier
The encoder multiplier may be either -4, -2, -1, 1, 2, or 4. A positive
encoder multiplier will count up with encoder pulses, negative counts
down. A multiplier of 1 counts on the rising edge of the A channel. A
multiplier of 2 counts on the rising AND falling edge of the A channel.
A multiplier of 4 (highest resolution) counts on the rising and falling
edge of the A and B channels. This multiplier will directly effect the
Encoder Counts/Unit on this Axis Parameters Dialog.
For example, if you have a 1024 line encoder, a multiplier of 4, and a
User Unit of Revs (motor revolutions) then 4096 should be used for
Encoder Counts/Unit.
Drive Enable Output #
Drive Enable assigns an output to the drive enable switch. The
default output is 32 for the first axis and increments by one for each
axis thereafter.
24
NOTE:
If a potential runaway condition is detected, a warning
dialog box will appear. It means the Encoder Multiplier
and the Command Gain do not match recommended
polarities based on drive type and Loop Control (vel/torq)
selections. Change the polarity of the multiplier to “-” and
the gain to “+”.

Reconfigure
If you change the Axis Connection Number to a different axes type,
your application will be reconfigured to the new axis type. This is
mainly accomplished by deleting instructions (or portions of
instructions) when the axis is changed to pulse.
25
Axis Servo Loop Options
The Axis Servo Loop Options dialog box allows you to modify the
setup of the servo parameters when the Application is downloaded to
the controller. These settings can be changed using the Program
Control dialog box or by instructions within the Motion Program.
Figure 15
Servo loop Dialog Box
The Axis Servo Loop Options are the Proportional, Integral,
Derivative (PID), Feedforward Velocity and Feedforward
Acceleration parameters. There are two parts to the output filter
(Low-pass and Notch) that you can adjust.
Defaults Button
This button will change all options to default values based on the
Drive/Motor/Loop control selected on the axis parameters dialog box.
26
Proportional
Gain
The proportional gain is the coarse adjustment which is used to
calculate the proportional term. The gain is multiplied by the total
following error at the time of the servo loop update. If the error is zero
the Proportional term is zero. The error may be positive or negative.
The larger the error the larger the proportional term for a constant
gain. The units are Volts/Error Pulses.
Integral
Gain
The integral gain is used to calculate the integral term. The integral
term is an additive term that is only modified by addition (could be a
negative value being added) at each servo loop update. This term is
calculated by integrating the following error over time and
multiplying the total error by the integral gain.
Delay
The integral delay is the time after a move is completed before the
integral term is calculated. This is typically used with a time value
(i.e. > 0) this causes the integral term to be calculated only after
motion has completed. If the integral delay is zero then the integral
term is calculated at all times, even when during motion. This term
is useful to fine tune the balance of the controller and the LX/MX
drive.
Limit
Since the integral term is additive with each calculation, over time,
it may become unbounded. The integral limit is to control (limit) the
voltage output produced by the integral term. The units are volts.
Derivative
Gain
The derivative gain is a fine tune adjustment to dampen oscillation
of the output signal. The derivative term adjusts the output based
27
upon the change (rate of change and direction of change) of the error.
This gain should be zero when the Axis is connected to the Velocity
loop of the LX/MX Drive.
Sample
The derivative width controls the rate at which the derivative term
is calculated this width is rounded up to the nearest servo loop
update calculation.
Filter
Low-pass Frequency
If the frequency is zero the low-pass filter is disabled. If the frequency
is non-zero the low-pass filter will filter high frequency output
oscillations down to the cutoff frequency entered here.
Notch Frequency
If the frequency is zero the notch filter is disabled. The notch filter is
designed to remove specific output oscillation frequencies that may
cause machine vibration. This edit field specifies the center
frequency for the notch filter.
Notch Bandwidth
This edit field is used with the notch frequency field described above.
This field specifies the frequency width for the notch filter.
Feed Forward
Velocity
The Feed Forward Velocity term is an open-loop calculation (not
error based) that is used by the controller to reduce the following
error during constant velocity motion.
Acceleration
The Feed Forward Acceleration term is an open-loop calculation (not
error based) that is used by the controller to reduce the following
error during acceleration.
28
Axis Limits
The Axis Limits dialog box allows you to define limits for the motion
of the axis. These limits control the setting and clearing of Predefined Variables. If a travel limit is exceeded a bit variable is turned
on. If you need to disable the drive when limits are exceeded.
!
CAUTION
Following error, travel limit A and B do not cause the AXIMA controller
to Stop motion, they only set flags which allow you to determine the
action, usually in one of the AXIMA Software PLC Programs.
Figure 16 Axis Limits Dialog Box
Position
Following Error
The AXIMA controller continuously checks the commanded position
from the DSP and feedback position from the encoder (or motor). The
difference between them is the following error. If the following error
29
exceeds the value you enter here, the AXIMA clears a bit "Not
Following Error".
Travel Limits (A and B)
This parameter sets the high and low limits monitored by the
"Within Travel Limit A" and "Not Within Travel Limit B" bits
Position Band
The values you enter here set the in position (motion completed)
error limits monitored by the "Not In-Position" bits. When the in
position error of a given axis is outside of its in-position band, the not
in position bit is set.
Command
Command Limit
Depending on which option you select for the Loop Control parameter
in the Axis Parameters dialog box, this parameter limits either the
velocity or the torque produced by the drive.
The DAC signal must be wired to either the drive velocity input or
the drive torque input depending on the loop control mode. Refer to
the LX/MX drive manual for further information on command signal
wiring.
Each drive (axis) in your application may have a different maximum
command/velocity rating. Refer to your drive's technical manual for
maximum command rating for each drive in your application.
Command Band
This parameter sets the positive and negative command limit for the
analog output to the DAC which is monitored by the not command
band bit. If the drive is connected for velocity mode, these values
serve as the velocity limits. If the drive is connected for torque mode,
these limits serve as the torque limit. The output will be clamped at
this limit.
If the analog output is more negative than the negative value you
enter here, the axis and coordinate system not in command band bits
are cleared. If the analog output is more positive than the positive
30
value you enter here, the axis and coordinate system not in command
band bits are set. The units are in volts.
Programs
The dialog box used for creating and editing Motion, PLC or
Auxiliary Programs are very similar with the exceptions listed below:
•
•
•
•
•
Auxiliary Programs include a user defined name.
PLC Program instructions may not be commented.
PLC Programs do not have a priority adjust option.
Motion Programs default to High Priority.
Auxiliary Programs default to Low Priority.
Program Quantity
Each of the program types (Motion, PLC, and Auxiliary) have limits
on the total number of each.
•
Number of Motion Programs <= 8 (coordinate systems)
•
Number of PLC Programs <= 8 (coordinate systems)
•
Number of Auxiliary Programs <= 15 minus the number of
Motion Programs
•
Number of High Priority Programs <= 8
•
Number of Low Priority Programs <= 7
Program Verification
All programs (Motion, PLC and Auxiliary) are verified as you edit
them. Warning messages are presented as inconsistencies are
created within any program. Examples include; deleting referenced
variables, labels and axes. See the Troubleshooting section for a
description of the messages produced by the AXIMA Software.
31
Editing Programs
The dialog boxes for each of the three program types (Motion, PLC
and Auxiliary) have the same basic layout that includes an
instructions area that is divided into two sections, groups and
instructions. The group list lists the available instruction groups in
alphabetical order. The instruction list lists the instructions
available with the group you have highlighted in the groups area. To
view all programming instructions available at once, select All from
the groups area.
To add an instruction double click on the desired instruction, an
instruction dialog box is displayed asking the necessary information
specific to that instruction. After entering all necessary information
click on the OK button.
Most edit fields in the instruction dialog boxes allow for the entry of
user variable names. When the focus is changed and if a variable
name was entered the software will check for a variable defined with
this name. If the name is not found the Variable Definition dialog box
will appear.
Variables Button
The variables button opens the variable list dialog box where you can
add, edit, delete or view references to a variable.
Find Button
The find button allows you to quickly locate a specific line of text or
key word in your program. The find option is case sensitive. Which
means you must type the word (or words) exactly as they appear in
your program including capitalization, spaces, dashes, numbers and
any other ASCII characters used.
Edit Button
To edit an instruction, highlight the desired instruction line (in the
program list) then click on the edit button or simply double click on
the instruction line. The edit button is grayed if you have more than
one instruction highlighted at a time.
32
Cut Button
This feature allows you to cut an instruction (or group of instructions)
to the AXIMA clipboard.
Copy Button
This feature allows you to copy an instruction (or group of
instructions) to the AXIMA clipboard.
Paste Button
The paste button will insert the contents of the AXIMA clipboard into
the program based upon the append check box. The Paste button is
grayed if the AXIMA clipboard is empty.
Up/Down Buttons
The up/down buttons are used to move the highlighted instruction(s)
up one line or down one line.
Comment Out
The comment out check box is used to temporarily remove an
instruction line, or lines, from a program. To comment out an
instruction line highlight the desired line then click on the comment
out check box. When an instruction is commented out, three stars are
inserted (*) at the beginning and end of the instruction line.
Run On Power Up
The run on power up check box, when checked, will cause that
program to begin running when power is applied to the AXIMA
controller. It is necessary to set the run on power up in at least one
program.
Append
The append check box, when checked, will cause instructions to be
added directly below the currently highlighted line (in the program
33
list). If not checked, the added instruction is added directly above the
highlighted line.
Program Priority
This feature is only available in Advanced Mode. This feature allows
you change the priority of a program.
34
Variables
Variables are either User Defined or Pre-defined. See Pre-defined
Variables section for a complete list of Pre-defined Variables. The
Scope of User Defined Variables can be either Local or Global. The
Type can be set as a Bit, Integer or Floating Point.
Variable List
The Variable List dialog box lists all of the variables that have been
defined. From this dialog box you can add, edit, delete or view
references to a variable. After adding or editing a variable, selecting
the OK button will save and validate that variable. The cancel button
will undo any changes you may have made while this dialog box was
open.
You can quickly reference information in this dialog box by changing
the amount of information displayed and how it is displayed using
the Hierarchy Level and Sort By buttons respectively.
Figure 17 Variable List Dialog Box
35
The Variables list box displays several pieces of information about
each variable you define including:
•
User assigned variable names.
•
Scope (Local, Global or Pre-defined).
•
Generic name (e.g. LA#).
•
Type; Bit, Integer or Floating Point (Bit, Int, F32 or F64
respectively).
•
Array size.
•
Initial value.
•
Modbus® or Data Highway® addresses.
•
Pre-Defined Variable descriptions (e.g., Desc: Output-32).
•
Program name and number, and the Coordinate System name
associated with Local Variables.
Each variable has a generic name associated with it which is only
displayed when the Advanced Mode option is checked in the
Preferences dialog box.
Example variable from the Variable List dialog box:
ACCEL_RATE(10) [LA0(10)] Int
where:
ACCEL_RATE is the user assigned name
(10) is the array size
[LA0(10)] is the generic name (and array size)
Int stands for Integer type variable.
Hierarchy Level Buttons
The Hierarchy Level buttons are used to globally expand and
contract the hierarchy levels of the variables in the Variables List
dialog box. When a variable is preceded by a plus sign (+), you can
36
double click on it to expand an individual variable or click on the
highest number hierarchy button available (button #2 or #3) to
expand all variables simultaneously.
Expanding a variable displays additional information about that
variable such as:
•
Generic number/Bit values (Bit# P#, LV#, LA#, DV#, DA#, SV#,
SA#).
•
Array size.
•
Pre-defined Variable group and description.
•
Modbus or Data Highway Plus addresses.
•
The Coordinate System and Program associated with a Local
Variable.
Edit/Add Button
To add a variable click on the add button. The Variable Definition
dialog box will appear to define the name, type, scope, quantity and
parameter group. Arrays of variables are allowed (these are
referenced in with ( )’s)
To edit a variable highlight the variable in the list then click on the
edit button or double click on the variable in the variable list window.
References Button
The "References" button is used to determine if the currently
highlighted variable is referenced in any program. If the variable is
referenced, AXIMA will display the variable references dialog box
which displays the coordinate system, program and the instruction
that the variable reference occurs in.
You can go to the program directly from the variables references
window by clicking on the "Edit Program" button or by double
clicking on the reference you wish to edit. If the variable highlighted
37
is not referenced in any programs, AXIMA will pop-up a message
that says "Variable {name} is not used in any program".
Figure 18
Variable References Dialog Box
Unreferenced Button
This feature is used to quickly identify all variables that are
currently not referenced in your application. When this button is
clicked, AXIMA will search all motion, PLC and auxiliary programs,
highlighting all un-referenced variables it finds. Once the unreferenced variables are selected, they can be deleted which will freeup valuable memory space.
Sort By
The "Sort By" radio button determines how the variables are sorted
in the Variables List dialog box. You can sort the variables by Name,
Scope, Type or Modbus/Data Highway addresses (if available). The
sort by option you select is aligned to the left side of the dialog box.
Modbus/Data Highway Address
This data window displays the Modbus or Data Highway address of
the highlighted variable. If the highlighted variable has not yet been
assigned to a Modbus/Data Highway address, this box will be empty
38
and the Assign button will display the next available address based
off the previously assigned address.
Clear Button
The Clear button will delete the Modbus or Data Highway addresses
from all highlighted variables.
A convenient way to view the Modbus or Data Highway addresses, is
to select the Modbus or Data Highway radio button in the Sort By
area.
Compress Button
This button used to re-number all Global and Local Variables for the
application thus reducing the amount of memory used by variables.
When the Compress button is pressed the following warning message
is displayed:
Figure 19 Variables Compress Warning
As new variables are defined they will be assigned the next
sequentially available number and will retain that number until the
variable is deleted or the Compress button is clicked.
39
Variable Definition
Selecting the Add or Edit buttons will open the Variable Definition
dialog box which allows you to define/or edit variables to be used in
Motion, Auxiliary and/or PLC Programs.
Figure 20
Variable Definitions Dialog Box
Name
You can enter up to 40 alpha-numeric or underscore characters
(spaces are not allowed) for the name of each variable. The first
character must be an alpha (A through Z).
Scope
The "Scope" defines the variable as Global, Local or Pre-defined. The
scope you select for a variable will determine the "Type" you can
assign to that variable. For example, if you select Local, all four
"Type" options will be available, however, if you select Pre-defined,
the floating Point 64 type will be grayed and if you select global, the
floating point 32 type will be grayed.
40
•
A Global Variable is available for use in all motion, auxiliary
and PLC programs.
•
A Local Variable is available only in the program where it was
originally created.
•
A Pre-defined Variable is a controller defined variable which
can be used globally in all motion, auxiliary and PLC programs.
Type
The "Type" defines the variable as a bit, integer, floating point 32 or
floating point 64.
•
A bit is a single binary value either -1 for true or on, 0 for false
or off.
•
An integer is any whole number between +/- 2,147,483,648.
•
A floating point 32 value allows for a signed seven (7)
significant digits plus a signed exponent and decimal point.
•
A floating point 64 value allows for a signed fifteen (15)
significant digits plus a signed exponent and decimal point.
Groups/Selected Variable
These options are only available when the variable Scope is defined
as "Pre-defined" otherwise it is grayed. To view the list of the
different groups available, click on the arrow button on the right side
of the combo box. The list of groups available is different depending
on the variable "Type" you select. Additionally, the list of "Selected
Items" is different depending on the "Group" you select. The table
below shows all possible pre-defined variables.
Array Size/Initial Value
This field will display "Array Size" when Local is selected, "Initial
Value" when Global is selected and be grayed when Pre-defined is
selected for the variable type.
41
Array variables may be any size but large arrays will consume large
quantities of memory. Arrays are used with PLS instruction, CAM
tables and many other uses.
Initial Value is used with global integer and floating point variables
only. The initial value may be set with this dialog box or may also be
set by the Quick Move Instruction (available from the Immediate
Instructions).
This value is initialized within the controller immediately after the
downloading is completed. This value is also retrieved upon
uploading the application from the controller.
Modbus/Data Highway Address
This data window allows you to enter a Modbus or Data Highway
address to the variable.
The drop down box of Pre-defined Variables is dependent on your
Application configuration. For example, only the defined axis
variables are available in the drop down lists.
This dialog box is also launched from instructions when a new
variable name is typed in.
Scope and type options are grayed depending on where the variable
definition is launched. You cannot create Local Variables unless you
have the Program Edit dialog box open (then either the Variables
List dialog box or an instruction must be opened). When the dialog
box is launched from an instruction, only the type and scope options
are allowed.
42
Cut, Copy, Paste
This feature allows you to cut or copy a Coordinate System, an axis,
a program or part of a program (Motion, PLC or Auxiliary) to a
special AXIMA Software clipboard (as opposed to the Windows
clipboard), then paste that Application into the target Application
which may be the same Application or to another Application.
When an Application fragment (e.g., Coordinate System) is cut or
copied then pasted, all components of the fragment (e.g., Axes,
Motion, and PLC Programs) are also pasted. This allows the
combining of Coordinate Systems from two different Applications.
Program fragments (i.e. instructions) may also be cut or copied then
pasted. This is useful when duplicating motion and or control logic for
similar Applications or Coordinate Systems.
It is important to note that variables may be automatically pasted if
no conflicts or unresolved references exist.
Cutting and Copying Application Items
An Application fragment is any part of an Application displayed in
the hierarchy on the left side of the Application window such as
Coordinate Systems, Axes, Programs, etc. You can select one
Application item at a time to be cut or copied from the Application
hierarchy. The table below list the Application items which can be
copied or cut:

Cutting, Copying Program Instructions
When creating or editing programs (Motion, PLC or Auxiliary), you
can cut or copy program instructions then paste them into other
programs or to a new location of the same program. However, there
are some restrictions when pasting instructions from one program to
another, for example, you can not paste PLC instructions into Motion
or Auxiliary Programs (see table below). Instructions may only be
cut, copied and pasted from within a program dialog box.

To select a group of instruction lines simultaneously you wish to cut
or copy, highlight the instruction line you wish to start with, while
continuing to hold down the left mouse button, drag the cursor to the
44
instruction line you wish to end with and release the button. Or, you
can highlight the starting instruction line, move the cursor to the line
you wish to end with, press the Shift key and select the ending
instruction. You can then either cut or copy the selected lines using
the cut or copy buttons.
NOTE:
Your selection cannot include partial IF-THEN/ENDIF
clauses. If you do not select the entire IF-THEN/ENDIF
clause, cutting and copying is not allowed.
Pasting from the AXIMA Software Clipboard
When the Application fragment on the clipboard is pasted to an
Application, some Application items will be replaced and others will
be added depending on the nature of the item.
The following table shows weather an item on the AXIMA Software
clipboard will replace or be added to an Application.

Pasting Restrictions
The following restrictions apply when pasting Applications items
from the AXIMA Software clipboard into the target Application:
•
When pasting a Coordinate System into an Application, pasting
is not allowed if the resulting number of Coordinate Systems or
axes would exceed the maximum number allowed in the target
Application.
•
Pasting an axis is not allowed if the resulting number of axes
would exceed the maximum number allowed in the target
Application.
•
Pasting a program of High/Low Priority to the target
Application where there are no more programs available with
that priority.
•
Pasting Latch, Counter and Timer instructions that cause the
maximum eight to be exceeded.
•
Pasting an External Time instruction requires a Coordinate
System with an encoder selected for external time.
•
When pasting program instructions into a Motion, PLC or
Auxiliary Program, you will not be allowed to paste instructions
into a program where the instruction(s) are not supported (e.g.
instructions that are only allowed in PLC Programs can not be
pasted into Motion or Auxiliary Programs).
If you attempt to paste an Application item that violates one of the
restriction above, AXIMA Software will display an error message box
which will briefly explain the problem.
46
Conflicts Resolution Dialog Box
The Conflict Resolution dialog box is automatically displayed when
there are conflicts or unresolved references existing between the
Application fragment in the AXIMA Software clipboard and the
target Application.
This dialog box is divided into two windows, Clipboard and Target.
Each of these windows are described in more detail below.
Figure 21 Conflict Resolution Dialog Box
Conflicts Resolution Dialog Box Hierarchy
Application items that are cut or copied to the AXIMA Software
clipboard are displayed in a hierarchical fashion similar to
applications in the AXIMA Software window.
47
The top level (flush left) Application items in the clipboard window
can be one of the following Application items:
-Coordinate Systems
-Axes
-Encoders and Command Numbers
-Instructions
-Variables
-Analog Inputs
-Programs
-PLC Resources
The type of conflict level is indented once from the left and can be one
of the following:
-Unresolved Reference
-Unassigned
-Conflict
-Duplicate Name
-Pre-Defined Variable conflict
The conflict item level is indented twice from the left and identifies
the conflict item. For example, the top level is Coordinate System.
The next level in is 'Unresolved Reference', and the last level in from
the left is '5th Winder Servo'. Which simply means that there is an
unresolved reference in the 5th Winder Servo Coordinate System
that needs to be resolved before the paste operation can be completed.
By default, this level is preceded by a plus (+) sign, which can be
expanded by double clicking which will reveals the details level of the
item that caused the conflict.
As you highlight items in the hierarchy, specific details about that
item will be displayed above and below the clipboard and target. This
data is provided to assist you when resolving conflicts between the
clipboard data and the target Application.
48
Resolving Conflicts
All conflicts must be resolved before a paste operation may be
completed. It is strongly recommended that you resolve all conflicts
displayed in this dialog box starting with the first hierarchical level
and working your way down to the last level. Resolving the first level
hierarchical conflicts first, often will result in lower level conflicts
being automatically resolved.
Conflicts that occur when cutting, copying and pasting application
items can be organized into one of the following two categories,
Resource Conflicts or Unresolved References.
Resource Conflicts
Resource Conflicts refer to AXIMA Software resources such as
Encoders, Command Connectors, DAC's, Timers, Inputs, Outputs
and Names.
Example 1
If you cut or copy an axis from one Coordinate System to another, and
the target Coordinate System has an existing axis with the same
name, a Duplicate Name conflict will occur.
Example 2
If you cut or copy an axis that uses encoder 1 and command number
1 from one Coordinate System to another, and the target Coordinate
System has an existing axis which also uses encoder 1 and command
number 1, a Encoder Conflict and a Command Number Conflict will
occur.
Unresolved References
Unresolved references are caused by program instructions which
refer to Pre-defined Variables, Coordinate Systems, Axes, etc. that
were not pasted. Unresolved references can occur when pasting part
of a program into another program or when pasting an entire
program into a different Coordinate System (or Application).
49
Example 1
If you attempt to paste a program that has an instruction that
references a Pre-defined Variable that does not exist in the target
Coordinate System (or Application), an unresolved reference will
occur.
Example 2
If you attempt to paste a program that has an instruction that
references an axis that does not exist in the target Coordinate System
(or Application), an unresolved reference will occur.
The table below shows the conflict types that can occur in each
category.

Analog Input Configuration
Configuration Overview
There are eight analog input channels available which can be
individually configuration with the Analog Input Configuration
dialog box. Each channel represents a terminal on the analog input
terminal block located on the front panel of the AXIMA controller.
These inputs are sampled at the servo interrupt rate (200
microseconds is the minimum SUI).
Figure 22 Analog Input Conversion Diagram
The Connection Type you select in this dialog box must match the
physical wiring on the analog input terminal.
Analog Input Configuration Dialog Box
To access the Analog Input Configuration dialog box, follow the steps
listed below:
1. Double click on the words "Controller Options" near the top of
the hierarchy view (left side of the edit window) to display the
Controller Options dialog box, then check the Analog Input
check box.
2. Highlight the words "Analog Inputs" in the hierarchy view (left
side of the edit window).
55
3. Double click on any line within the analog input channel text in
the details view (right side of the edit window).
Figure 23
Analog Input Configuration Dialog Box.
Configuration Steps
The first time this dialog box is opened all channels will be disabled
(the "Enable This Channel" check box is empty). To configure a
selected channel follow the steps below:
1. Select the channel you wish to configure.
2. Check the Enable This Channel checkbox.
3. Choose the connection type, either Differential or Signal-Ended.
A differential type connection is typically more noise immune
than a single ended connection.
4. Enter the Minimum and Maximum Voltages. Both the
Minimum and Maximum Voltages must be within ± 10 volts
and the Minimum Voltage must be less than the Maximum
Voltage
56
5. Enter the User Units and the Minimum and Maximum Values
(in user units) which makes the analog input voltage
meaningful to your Application.
6. Select a single input terminal if you are configuring a signal
ended or a positive and a negative terminal if you are
configuring differential inputs.
7. The last step in this dialog box is to enter a Variable name. You
can enter a new or existing Pre-defined Variable that
corresponds to the Analog Input reading for the selected
channel. The range of this variable will be within the minimum
and maximum user units.
The following criteria must be met before you can select another
channel tab or press the OK button:
•
The minimum voltage value must not be the same as the
maximum voltage value.
•
The user units must be specified. The initial default is volts.
•
For a differential channel, the positive and negative terminals
must not be connected to the same analog terminal.
To configure another channel, select the next channel tab and
perform the steps listed above for each channel you wish to configure.
Assigning Variables to Analog Input
Channels
Each analog input channel must be assigned to a variable name
which can be used in a Motion or an Auxiliary Program. When you
enter a variable name, a Pre-defined 32 bit floating point Variable is
automatically created and assigned to the currently selected channel.
If a variable name has already been assigned to the pre-defined
analog input variable, that name will be displayed variable data box.
57
Analog Input Calibration
Depending on the accuracy required by your system, analog inputs
can be used without calibration, however, calibration of an analog
inputs minimum and maximum voltages is necessary in order to get
accurate results. This process requires online communications with
the AXIMA controller, therefore, calibration is allowed only when you
are online with an Application.
The Analog Input Calibration dialog box is accessed by selecting
Calibrate from the Tools pull-down menu. This menu item is enabled
only when:
•
You are online with the Application you will be calibrating.
•
The Analog Input option has been enabled for this Application.
•
The Analog Inputs item in the hierarchy view is highlighted.
When you select Calibrate from the Tools menu, the Analog Input
Calibration dialog box appears as shown:
Figure 24
58
Analog Input Calibration Dialog Box.
Expanded I/O Option
Expanded I/O Overview
The expanded I/O option adds 32 optoisolated inputs and 32
optoisolated outputs to the standard I/O which gives you a total of 64
inputs and 64 outputs.
The expanded I/O option requires that 24 VDC power be supplied to
the AXIMA controller and the external components (if this option is
used). The total current requirement should be calculated by the user
based on their unique configuration in order to properly size the 24
VDC supply. (See your AXIMA controller’s installation manual for
more information about expanded I/O options.)
Expanded I/O Software Setup
The Expanded I/O option is selected in the Controller Options dialog
box (accessed from the Options menu). The 32 expanded inputs and
32 expanded outputs are enabled by checking the Expanded 64 DI,
64 DO radio button.
59
Figure 25
Controller Options - Expanded I/O
Assigning An Expanded I/O To A Variable
Expanded I/O's are assigned to variables exactly the same as
standard I/O's. To select an expanded I/O Pre-defined Variable, click
on the Pre-defined and the Bit radio buttons, select either Inputs or
Outputs from the Groups select box, then select the expanded input
or output number you wish to use from the Selected Variable scroll
box.
60
Figure 26 Expanded Input #01 Assigned To Variable Name
"SENSOR INPUT"
Using Expanded I/O in an AXIMA Program
When writing an AXIMA Software program, the expanded I/O is used
in the same way as the standard I/O. An important difference to be
aware of when using the external components option is the time
delay inherent in the digital Opto22® modules.
NOTE:
This time delay is the additional amount of time it takes
for inputs to be recognized or outputs to change state,
therefore, time critical I/O's should be assigned to the
standard I/O or, if they are electrically compatible, use the
direct wire option.
Shown below in an insert of a Motion Program which sets the Enable
Expanded I/O bit and uses the SENSOR_INPUT variable in a Wait
Instruction which was assigned to Expanded Input #01 in the sample
dialog box above.

Overview
This section describes the instructions that are used by the AXIMA
Software. These instructions are presented first in a tabular format
to show when each instruction may be used. They are also listed
alphabetically including detailed information.
Instructions are used to control the operation of the AXIMA
controller. Depending on the instruction, they can be used in either a
Motion, Auxiliary or a PLC Program or in Program Control.
Instructions are inserted, deleted or commented in the program
dialog boxes.
Each instruction is associated with a dialog box that is presented
when you insert or edit an instruction. Most fields in the instruction
dialog boxes allow the entry of a value or a variable name. If you
enter a value, it is verified against any limits that may be associated
with that instruction. A variable name may be entered even if the
variable name is not defined yet. When the OK button is pressed, a
verification is made for all variable used. You will be prompted to
define any variables not defined.

Instruction Definitions
All instructions are listed alphabetically on the following pages.
Absolute Path Shift Instruction
Group:
Path
See also:
Relative Path Shift Instruction
Description:
This instruction will cause the path of all motion in the Coordinate
System to be shifted by an absolute amount. The amount of the Path
Shifts for each axis is defined by the offset in user units. This
instruction does not by itself cause any motion.
Figure 28 Absolute Path Shift Dialog Box
Arc Move Instruction
Group:
Motion
See also:
Sinusoidal Move Instruction
Description:
This instruction produces a circular arc motion. The plane of the
motion is defined by the first and second axes. The Start Point and
Center Point is specified for both axes. The End Point is calculated
based on these values, the Degrees Of Motion and the Motion
Direction. The End Point is provided to confirm the actual motion.
The Start Point and Point Center values cannot be variables. If
variables are required use the Sinusoidal Move Instruction to
generate the arc.
67
The Move to Start Point, if checked, will produce an absolute move to
the start point before the arc move is started. The Compound Into
Next Move, if checked, will compound this move into the next move.
Compounding is accomplished by smoothly accelerating or
decelerating to the velocity of the next move. Not available in
Immediate Mode.
Figure 29
68
Arc Move Dialog Box
The value you enter in the Degrees Of Motion box will determine the
sweep angle. The direction of the arc move is determined with the
Motion Direction radio buttons.
Figure 30 Arc Move Diagram
Automatic Vector Instruction
Group:
Velocity
See also:
Manual Vector Instruction
Description:
This instruction controls how the coordinate system move vector is
calculated. The weight of an axis determines how much the axis
contributes to the vector calculation. The default weight value is 100
percent for all axes.
With the Automatic Vector Instruction, the vector length of the
coordinate system move is calculated using the following formula:
vector length = sqrt ( ∑ ( delta (axis)2 * weight (axis) ) )
where:
delta (axis) = distance the axis is moving
weight (axis) = vector contribution of axis
The Coordinate System will move (caused by a move, arc, sinusoidal
move, etc.) from the current position to the specified destination,
using the current velocity, acceleration, deceleration and feedrate
69
override settings to control its velocity profile. The vector length
calculated here effects only the velocity of the move because the
velocity profile is generated based upon the vector length. The vector
length is equal to the actual distance traveled if all weights are set to
100 percent. All axes in the coordinated move will start when the
coordinate system starts and reach their target positions as the
coordinate system move finishes its move.
For single axis moves the weight should remain or be set to 100
percent.
In many multi-axis configurations, it is not necessary (nor desirable)
to have all the axes contributing to this calculation. For example, in
a configuration containing three Cartesian axes and a rotary axis,
just the Cartesian axes need to be included in the vector distance not
the rotary axis.
For non-contributing axes, the vector weight should be set to zero. If
these axes are to be moved by themselves, the automatic vector
calculation must be overridden by using the Manual Vector
Instruction.
Figure 31
70
Automatic Vector Dialog Box
Axis Instruction
Group:
Other
See also:
Open Servo Loop, DAC Output
Description:
The Axis Instruction turns “On” or “Off” the servo loop associated
with an axis. Turning off unnecessary servo loops will reduce CPU
load and improve system performance. It is suggested that this
instruction be included at the beginning of a Motion program to turn
off all unused axes. When the Axis is off the DAC output is available
for direct program manipulation as an analog output.
Figure 32 Axis Dialog Box
Call Subroutine Instruction
Group:
Flow
See also:
Label Instruction, Return Instruction
Description:
This instruction causes an unconditional call or jump to a subroutine.
Each subroutine must be terminated with a Return Instruction.
Select a label (previously defined) from the list provided in the dialog
box. If no labels are defined, the Call Subroutine Instruction is not
allowed. Subroutines may be nested up to 10 levels deep.
Figure 33 Call Subroutine Dialog Box
71
Command Band Instruction
Group:
Limits
See also:
Max Command Band, Min Command Band, Coordinate System Not
In Command Band, Axis Not In Command Band, Command Limit
Instruction
Description:
This instruction sets the command band limits monitored by the "Not
In Command Band" bits. The Command Band Instruction only
defines bit monitoring boundaries, it does not affect the analog
command output in any way. See the Command Limit Instruction for
information on physical output clamping.
Command Band for Stepper axis is entered in Counts/Seconds. This
is converted into volts when this instruction is downloaded. If you use
a variable for Stepper the value must be in volts.
Volts = (counts/second)/(409.6/servo interrupt period)
This instruction overrides the initial values in the a Axis Limits
dialog box. If power cycled, the value automatically reverts back to
the value in the Axis Limits dialog box.

Command Limit Instruction
Group:
Limits
See also:
Max Command Limit, Min Command Limit, Coordinate System Not
Command Limit, Axis Not Command Limit
Description:
This instruction sets the voltage limits monitored by the "Not

Instruction cause the output of the servo loop to be clipped at the
given values. See the Command Band Instruction for non-clipping
command monitoring.
This instruction overrides the initial values in the Axis Limits dialog
box. If power cycled, the value automatically reverts back to the
value in the Axis Limits dialog box.

73
Comment Instruction
Group:
Flow
Description:
This instruction allows the user to enter comments anywhere in the
Motion or Auxiliary Programs (comments are not allowed in PLC
Programs). Comments are used to record program design issues such
as how and why the instructions are used or how the program is
designed.
Figure 36
Comment Dialog Box
DAC Instruction
Group:
Other
See also:
DAC Gain, DAC Offset
Description:
The DAC Instruction gives you direct access to change the Gain and
the Offset of a D/A converter. The default Gain setting is 3276.8 and
the default Offset Ø.Ø volts, which supports a ±10 volt output.
The output voltage is inverted in the output stage of the hardware,
therefore the default DAC Gain will physically send out a negative
voltage for positive settings.
Figure 37
74
DAC Dialog Box
Derivative Gain Instruction
Group:
Servo
See also:
Derivative Term, Derivative Gain, Derivative Sample Period,
Derivative Sample Period Instruction.
Description:
This instruction is used to set the derivative gain for one or more
axes. The derivative gain set by this instruction overrides the initial
value set by the Axis Servo dialog box. The derivative term results
from the multiplication of the derivative gain times the rate of
change in the following error and is typically used to dampen
oscillation. The derivative term is calculated at every servo update by
default. However, the interval of this calculation may be modified by
using the Derivative Sample Period Instruction.If power cycled, the
value automatically reverts back to the value in the Axis Servo Loop
Options dialog box.
Derivative gain is typically not used when the AXIMA controller is
connected to the velocity command input of the drive. For more
information see, the “Tuning Procedures” section.
Figure 38 Derivative Gain Dialog Box
75
Derivative Sample Period Instruction
Group:
Servo
See also:
Derivative Term, Derivative Gain, Derivative Gain Instruction,
Description:
This instruction allows you to set the derivative sample period for
multiple axes in one instruction.
Derivative sampling period determines how often the following error
is sampled when calculating the derivative term. Setting this value
to zero will set the sampling to occur at the servo update interval set
in the Application Option dialog box. If power cycled, the value
automatically reverts back to the value in the Axis Servo Loop

Program Dwelling
Description:
The Dwell Instruction causes a delay in program execution specified
in the edit field.
It is important to note that the Dwell will begin when the instruction
is encountered in the program.
For example
In the case of a Move Instruction followed by a Dwell Instruction, the
dwell time will start when the motion starts since the move is
actually executed by the servo loop unless the move is a Wait Until
Complete move.
The minimum dwell time is one millisecond, maximum dwell time is
9,999,999 seconds.

Encoder Capture Instruction
Group:
Feedback
See also:
Hardware Capture, Capture Complete, Trigger Software Capture,
Software Capture
Description:
This instruction sets an encoder capture for one or more axes. For
each axis the edge sensitivity and source is defined. This instruction
enables a hardware position capture triggered from one of several
77
different sources. This can be either the encoder marker line or from
an external input.
After the instruction is executed, the next source edge will cause a
hardware latch of the encoder count to be stored in the hardware
capture value (a Pre-defined Variable) and sets the "Capture
Complete" bit. The latency on the capture is less than 100
nanoseconds for the marker channels or ten microsecond delay for
external input signals coming through the optoisolators.
It is also possible to initiate an encoder capture sequence through a
program by setting the trigger software capture bit. This captures all
of the encoder positions and transfers them into the software capture
Pre-defined Variables.

Description:
This instruction loads the profiler position with the following
formula.
Profiler Position = Encoder Position - Cam/Jog/Gear Position Backlash Compensation Position - Ballscrew Compensation Position
78
The result of this instruction is to set the secondary setpoint equal to
the encoder position for each axis listed. This instruction is useful to
learn the current axis position after the motor is turned manually
with the motor power off. If this instruction is done just before motor
power is applied, the controller will learn the new position and zero
the command signal, this will avoid the motor jumping when the
drive is re-enabled. An Encoder Match Requested flag is also
available which can be used by a PLC program.

All External Time Base functions require A4 or later firmware.
Description:
This instruction is used to switch the time base from the internal
clock to an external encoder (which is defined in the Coordinate
System dialog box) and is applied only to Coordinated Move, Arc and
Sinusoidal Instructions.
Figure 46 External Time Profile Dialog Box
NOTE:
When the Begin External Time box is checked, the

during the acceleration and deceleration phases of the motion profile.
This instruction will override the initial value set in the Axis Servo
dialog box. The correct value can be determined using the following
formula:
Feedforward Accel = Proportional Gain * Following Error/Accel
Where:
Following Error = error at a given acceleration (pulses)
Accel = the given acceleration (pulses / second2)

Description:
This instruction sets the velocity override for all subsequent
movements (by the profiler) for all axes in the coordinate system. The
override is a floating point percentage scaling factor for the
coordinate system's velocity profile. This instruction does not effect
motion caused by the Jog, Gear and Cam Instructions.
Feedrate override takes place immediately upon execution of the
instruction. If a move is in progress, the Coordinate System will use
its acceleration or deceleration settings to ramp to the new velocity.
A feedrate override of 200 percent will produce a velocity of twice the
velocity specified by the Velocity Instruction. A feedrate override of
25 percent will produce a velocity of one fourth of the velocity
specified.Feedrate Override can also be controlled by writting a value

Lock, Gear Stopping
Description:
The Gear Instruction allows you to synchronize the motion of an axis
(or axes) to an encoder signal. This instruction either disables,
enables or resets electronic gearing for a Slave Axis. The Gear
Definition Instruction is used to setup the necessary parameters
required for the desired motion (see Gear Definition Instruction
below).
Figure 52
88
Gear Control Dialog Box
The Slave Axis field allows you to select the axis (or axes) to be
synchronized to the master encoder selected in the Gear Definition
dialog box. When you select an axis, it will be displayed along with
the Action and Offset information in the Gear Controls window on the
right side of the dialog box. Each axis selected can have a different
Action applied to it (On, Off or Reset).
When turned “On”, enables gearing motion in the selected Slave Axis
(or axes) after the Gear Control Instruction is processed will be
synchronized to the master encoder selected in the Gear Definition
Instruction.
When turned “Off”, disables all gearing motion in the selected Slave
Axis (or axes) after the Gear Control Instruction is processed will no
longer be synchronized to the selected master encoder.
The Reset parameter resets the Gear Position to zero and adds the
Position value to the profiler position.
The value entered in the offset parameter (in user units) is stored
directly into the gear position. If the newly loaded gear position is
different than the previous value, the difference is added to the
profiler position. This allows the primary setpoint to remain
unchanged so the axis will not jump. Normally this value is left at Ø.
Gear Definition Instruction
Group:
Motion
See also:
Gear Position, Profiler Position, Primary Setpoint, Gearing Active,
Gear Control Instruction
Description:
In electronic gearing, encoder counts are used from the master
encoder source and are divided by the Master Encoder Counts Per
Unit specified in this dialog box. The Master To Slave Ratio is then
applied to produce a slave axis position change in user units. The
slave position is multiplied by the Slave Axis Counts Per Unit and the
results (if gearing is “On”) are added into the gear position. The gear
position is added to the primary setpoint. Gearing is turned “On” and
“Off” by the Gear Control Instruction.
In this dialog box the six check boxes to the left of Define Gear
parameters allow you to “enable” or “disable” each parameter
individually. In order for a gear definition parameter to be active it's
corresponding check box must be checked.

Gear Definition Dialog Box
The Master Encoder parameter selects the master encoder that the
Slave Axes will be synchronized to. The master encoder number here
corresponds directly with the master encoder connector on the front
of the AXIMA controller.
90
The Master Encoder Counts Per Unit value represents the number of
Master Encoder counts per user unit of measure (User units are
specified in the Axis Parameters dialog box).
For example
If your user units were feet, and your master encoder produced 4096
counts per revolution which equaled ten feet of linear movement,
your Master Counts Per User Unit would be:
4096 / 10 feet = 409.6 feet
The Master To Slave Ratio values is the ratio in user units of the
Master Encoder to the Slave Axis. To set an axis up for a 2:1 ratio (two
turns of the master equals one turn of the slave), enter two for the
Master parameter and one for the To Slave parameter.
The Acceleration parameter is used to smooth-out the velocity ramp
when the Gear Instruction is turned “On” or “Off” or if the gear ratio
is changed.
The Deceleration parameter is used to smooth-out the velocity ramp
when the Gear Instruction is turned “On” or “Off” or if the gear ratio
is changed.
The Reset parameter resets the Gear Position to zero and adds the
Gear Position value to the profiler position.
The Offset value entered in user units is stored directly into the gear
position. If the newly loaded gear position is different than the
previous value, the difference is added to the profiler position. This
allows the primary setpoint to remain unchanged so the axis will not
jump.

Encoder Position, Hardware Capture, Capture Complete, Special
Purpose I/O
Description:
This instruction allows the searching for a source input in one or
more axes. Each axis seek operation is actually done in series (one
after another).
When the source input is detected the AXIMA controller uses the
high-speed encoder capture to record the position. Then the motion
will decelerate to a stop and then move back to the exact encoder
position where the sensor was detected at which time the encoder
position will be reset to zero.
A cycle start request bit must be cleared for this instruction to
operate properly. The source may be one of the following:
•
The encoder marker channel for the select axis.
•
The encoder marker channel for the other axis in the pair (pairs
are defined as axes 1/2, 3/4, 5/6, and 7/8)
•
One of two Inputs.
The distance specified should provide enough motion to cause the
source input to be found.
If the marker source is the encoder marker channel, a minimum
distance should produce more than one motor revolution. This is to
ensure that motion is long enough to find the marker signal.
94
If the source is an input number, a distance should be provided to
move beyond the home sensor (or other external device connected to
the input). The capture complete flag can be monitored to vary the
source input.
!
CAUTION
You must allow enough movement clearance for the motor to
decelerate after the source sensor is detected.

The Integral Delay Instruction determines the amount of time, after
a move ends, before the integral term calculation begins. If the

Description:
This instruction modifies the integral gain used in the PID
algorithm. The integral term is calculated by integrating (summing)
the following error over a time interval and multiplying the total
error by the gain. The Integral Gain Instruction overrides the initial
value set in the Axis Servo Loop Options dialog box. If power cycled,
the value automatically reverts back to the value in the Axis Servo
Loop Options dialog box. The integral term is a summation value
that is not zeroed by setting the gain to zero. The formula is:
Integral Term New = (Integral Term Old) + (Total Error)*(Gain)
To zero the integral term the gain must be set to zero and the integral
limit must be set to zero, see the Integral Limit Instruction. When
using this instruction to modify the integral gain the Integral Limit
Instruction should be used to set the integral limit temporarily to
zero.
The Integral Gain Instruction will override the initial value set in the
Axis Servo dialog box.

Description:
This instruction modifies the integral limit used by the servo loop.
The units of the integral term is in volts. Since the integral term is
additive (the new integral term is calculated using the old integral
term), it may become unbounded and produce a voltage output of 10
volts. This is not desirable, so the integral term may be limited to a
voltage output specified in this instruction.
The Integral Limit Instruction overrides the initial value setting the
Axis Servo Loop dialog box. If power cycled, the value automatically
reverts back to the value in the Axis Servo Loop Options dialog box.
This instruction should be used to the temporarily set the integral
limit to zero if the integral gain value is modified. The integral limit
instruction will override the initial value set in the Axis Servo dialog
box.

Setpoint, Jog Position, Profiler Position, Jog Definition Instruction.
Description:
This instruction is used to control the starting, stopping and
resetting, and direction of the jog motion. The velocity, acceleration
and deceleration are defined in the Jog Definition Instruction dialog
box.
Jogging sets up an individual velocity profile for an axis based on the
current jog parameters. This profile ramps to a given velocity,
generating a jog position. The jog position is used during the
summation of the primary setpoint.
!
CAUTION
Jog commands are initiated immediately, they are not buffered. Which
means when a Jog Instruction is executed, the jogging motion is
started immediately and the program continues on to the next step.
Jogging will continue until a Stop is issued or the absolute or
incremental position is reached. Halting a program does not stop Jog
Motion.
100
For example
If a Jog Instruction is issued in the forward direction, then later a Jog
Instruction is executed in the reverse direction the axis will
immediately decelerate to a stop and reverse.
!
WARNING
Halting a program does not stop jog motion.
Likewise, if an Incremental Jog is executed and during the jog move
an Absolute Jog Instruction is executed the Incremental Jog
decelerates to a stop and the Jog Absolute Jog starts.
Figure 64 Jog Control Dialog Box
Jog Motion can be used simultaneously with the Move Instruction.
The motions will be summed together at the Primary Set Point.
There are seven Action options to chose from. You can select only one
Action option per Axis. Use the Add button to add (or the Delete
button to delete) an Axis to the Jog Controls list box.
101
The first two options (CW and CCW) are the user defined direction
parameters.
The Stop parameter is used to bring a jogging Axis to a stop. Each
axis must be assigned its own jog Stop within the Jog Control
Instruction.
Selecting the Reset button will cause the axis jog position to be reset
to zero. The old jog position will be rolled into the profiler position.
This is necessary to maintain the primary setpoint value so the axis
will not change position when resetting the jog position.
The jog reset is needed for returning to the "real world" absolute
position.
For example
A move of 5 revs CW and a jog of 10 revs CW from the home position
known as zero. Although the "real world" application movement
generated a 15 revolution motion profile CW, the move profiler
registers only 5 revs while the jog profiler registers 10 revs.
Therefore, a 15 CCW move of the move profiler would reset a "real
world" position of -10 revs CW (or 10 revs CCW).
To move back to the zero position it is necessary to do a jog reset (to
move the jog position into the profiler position) followed by a move to
absolute position zero.
The Profiler Position Into Jog Position button does the opposite of
Reset button. When this option is selected the profiler position is
rolled into the jog register which allows the jog position to always be
in the “real world” for absolute position.
The Incremental and Absolute move an axis the distance or to the
Position selected. These jog moves are similar to the Move
Instruction except there is no coordination between axes. Each axis,
even within the same Coordinate System, can be controlled
independently.
If you select Incremental, you will need to enter a Distance and a
Movement Direction. If you select Absolute, the Distance parameter
will change to Position and the Movement Direction parameter will be
grayed out. These values may be fixed numbers or variables.
Jogging can also be accomplished through the PLC Program with Jog
Forward and Jog Reverse Pre-defined Bits.

Manual Vector Instruction
Group:
Velocity
See Also:
Vector Length, Automatic Vector Instruction
Description:
This instruction allows manual velocity override of the vector length
calculations for moves. If the Vector Length is set to zero (with this
instruction), the vector length is calculated automatically as
described in the Automatic Vector Instruction.
When a move is executed, the coordinate system profiler controlling
the move is actually calculating the move velocity along the vector
length move for a certain number of "units" specified in this dialog
box. The velocity profile of this move is controlled by the current
105
velocity, acceleration, deceleration and feedrate override velocity
settings.
The purpose for this instruction is to allow you to define the velocity
as a relation to the vector length. This may be a more convenient
method to change the amount of time it takes to make a move rather
than recalculating the velocity, acceleration and deceleration. For
example, if the actual vector length is 10 user units and the manual
vector length is set to 5 the same move will be accomplished in half
the time. The actual distance moved is not modified by this
instruction.

The Move Instruction can be used to move one or more axes

Move list box (right hand side of dialog box) using the Add button.
Figure 71
Move Dialog Box
There are four different Move Types available at the top of this dialog
box. To select a Move Type click on its associated check box. The Move
Type you select will apply to all axes in the move. If none of the Move
Type boxes are checked, the move will be a simple coordinated move.
(i.e., when the Move Instruction is executed the profile is calculated,
the motion is started and the program continues on the next step
without waiting for the move to be complete.)
108
Trigger move provides a method of quickly starting the move based
on the status of a bit, usually an input bit. When the (Trigger) Move
Instruction is executed the motion profile is pre-calculated and the
move is buffered, no motion is started, the program continues to
execute. The Trigger attribute can be combined with the
Interruptible, Compound or Wait Until Complete attribute.
Interruptible move provides an easy method of stopping a move in
progress. The move can be either absolute or incremental. The Define
Move parameters (either Position or Distance depending on whether
its an absolute or incremental move) defines the move if the interrupt
bit condition is not satisfied.
If the interrupt condition is satisfied, the move will stop a specified
interrupt distance (defined with the Distance parameter under
Interrupt Parameters) from the point where the interrupt bit
condition was satisfied, this distance is always incremental.
If the interrupt distance is greater than the distance required to stop
at the programmed deceleration rate, the velocity will remain
constant and the programmed deceleration ramp will be followed to
stop at the interrupt distance point.
If the interrupt distance is less than required by the programmed
deceleration rate, a new decel rate will be calculated and the move
will stop at the interrupt distance point.
If the interrupt distance is zero or in the opposite direction of the
move the axis will attempt to stop or reverse as required a controlled
deceleration.
When an Interruptible move is executed the program remains at the
Move Instruction until the move is complete, regardless of whether
the interrupt bit condition satisfied. An interruptible move cannot be
compound into next move.
If the Application requires that an Interruptable move cannot come
to a stop at the end of the interrupt distance a generic (Final Velocity)
instruction can be used.
Compound Into Next Move provides a method of blending moves
together without decelerating to a stop between moves. Moves can be
compound into moves of the same or different velocities. If the
velocities are different the acceleration, deceleration and S-Curve
ramps will be followed. This is not available in Immediate Mode.
109
The Arc and Sinusoidal Instructions also have Compound Into Next
Move check boxes to provide an easy method of blending linear and
circular motions. When compounding moves together care must be
taken to ensure the instructions in between move commands do not
take longer to execute than the time it take for the previous move to
complete. In other words, you must be sure the program can find and
process a second move before the first one is complete.
Wait Until Move Complete inhibits program execution until the move
profile is complete. Complete, in this case, means the move is
complete when it reaches the Commanded position not Feedback
position. Wait Until Move Complete cannot be used in the same move
as Compound Into Next Move.
The user units of each axis is defined in the Axis Parameters dialog
box.
The Movement Type of each axis is defined as either Absolute or
Incremental. In Absolute moves the Position parameter specifies an
absolute position in user units. In incremental moves Distance
specifies a distance from zero in user units. With incremental moves
you can also define the direction of the move by selecting on of the
Movement Direction parameters.
Absolute and Incremental moves may be combined in a single
coordinated move. All coordinated axes will start and end their
motion at the same time. The velocity, acceleration, deceleration and
S-Curve (through separate instructions) are Coordinate System
attributes used for this move
Bit Control enables you to select the bit that will trigger the move by
typing the name of the bit in the Bit Control box then select the
Condition of the selected bit. During each servo interrupt the status
of the trigger bit is checked, if the selected Condition is satisfied, the
move then starts immediately.
Bit Control enables you to select the bit that will cause the move to
be interrupted by typing the name of the bit in the Bit Control box
then select the Condition of the selected bit. During each servo
interrupt the status of the Interrupt Bit is checked, if the selected
Condition is satisfied, the move is immediately interrupted.

The Normalize Instruction is only available with A4 or later
firmware.
Description:
This instruction normalizes the current position of an axis. A "MOD"
operation is done on the current position, resulting in a new current
position between zero and the length. If the Use Rotary Value box is
checked, the Length box is grayed and the Rotary Length Value from
the Axis Parameter dialog box is used. The primary setpoint and the
encoder count are adjusted accordingly in order to prevent the axis
from jumping. This instruction will not execute if the axis is in
motion.
Notch Filter Instruction
Group:
Servo
See also:
Summation Point, Filter Output Signal, Low-Pass Filter Instruction
Description:
This instruction initializes an output filter to act as a notch filter.
This instruction is useful in reducing any mechanical resonance that
may occur in the coordinate system. Setting the center frequency to
zero turns off the low-pass filter.
The maximum notch frequency (fn) is 1/2 times the inverse of the
servo update interval.
111
For example, if the servo update interval is 700 microseconds the
cutoff frequency is no more than 714.285 Hertz. In addition, the
width of the notch filter is also specified with this instruction.

Notch Filter
The Notch Filter Instruction will override the initial value set in the
Axis Servo dialog box. If power cycled, the value automatically
reverts back to the value in the Axis Limits dialog box.

PLS is “On”, it will operate as defined in the PLS Definition
Instruction.
Figure 75 PLS Control Dialog Box
PLS Definition Instruction
Group:
Other
See Also:
PLS Control Instruction
Description:
This instruction will define one of the eight Programmable Limit
Switches (PLS) that are executed at the servo update interval. When
a PLS is turned “On”, the AXIMA Software will use an encoder
position to index into an array. The value in the array is sent to the
digital outputs. Legal values for the PLS numbers are 1 through 8.
•
Correct values for "encoder" are 1 through 8.
•
The "offset" is an integer that defines a table offset value.
•
The "mask" is an integer bit mask for selecting only active
outputs desired.
•
The "ratio" is a floating point number that connects the source
encoder into the table index.
113
The following figure explains how the PLS parameters are used.
Figure 76
PLS Operation
You can choose one of eight encoders as source for the PLS. As the
encoder turns, the encoder position is multiplied by the multiplier
and the result is added to the offset which produces a table index.
This table index value corresponds directly to the array element
number.
The table index is used to retrieve an integer value (32 bits) from the
array specified. This integer value retrieved from the array is
masked with the Mask value to produce a final result. The final
result is written with the physical outputs on the AXIMA controller.
The PLS mask can be set up to modify anywhere from just one to all
32 outputs.
If the calculated table index is beyond the range of the array, the
outputs are clamped in the “Off” state. When the PLS is turned “Off”
the outputs will remain unmodified by the PLS.
NOTE:
114
Before using the PLS Definition Instruction, a Local
Integer Array must be defined in the Variable List dialog
box.
The array must be filled with integer values before the PLS Control
Instruction turns on the PLS.
Figure 77 PLS Definition Dialog Box
Calculating array element integer values:
For AXIMA controller
The array values are ANDed with the mask and written to the
AXIMA controller outputs 32 through 63. To control outputs 32
through 62 use the following formula:
Value = 2** (n-32) + 2** (n1-32) + 2** (n2-32) etc.
where n, n1, n2 etc. are the output numbers you wish to turn on for
a given element of the array,
Where:
n = output numbers 32 through 62.
e.g. turn “On” outputs 45 and 46. Value = 2** (45-32) + 2** (46-32) =
2**13 + 2**14= 24576.
To control output 63 the formula changes slightly
Value = 2 ** (n-32) + 2** (n1-32) + 2** (n2-32) etc. - 2** (31). Any time
output 63 is controlled by the PLS the Integer value will be negative.
115
For AXIMA 2000/4000 controller
The array values are ANDed with the mask and written to the
AXIMA 2000/4000 outputs 1 through 12.
To control outputs 1 through 12 use the following formula.
Value = 2** (n + 3) + 2** (n1+3) + 2** (n2 +3) etc.
Where n, n1, n2 are output numbers you wish to turn on for a given
element of the array.
Where:
n = AXIMA 2000/4000 output numbers 1 through 12.
e.g. turn “On” outputs 11 and 12. Value = 2** (11+3) + 2** (12 +3)=
2**14 + 2**15= 49152
Array values can be entered into the AXIMA from using the Formula
Instruction to make equate statements or a program loop in the same
program as the PLS. Array values can also be loaded serially from a
text file or an operator interface.
Equate statement examples:
PLS_ARRAY(0) = 1024
PLS_ARRAY(1) = 24576
PLS_ARRAY(13) = 384
Program loop to fill array example:
N=0
Label = Loop
PLS_ARRAY(N) = N +1
N=N+1
IF N < 5 then GOTO Loop
Rotary Length:
This parameter is only available with A4 or later firmware.
116
This parameter sets the PLS rotary length. The default rotary length
is 0 counts. If the rotary length is zero, the PLS is linear and the
output will be turned off if a table index is generated that lies outside
the boundaries of the PLS array. The internal input count is always
equal to the current value of the source encoder when a PLS is linear.
If the rotary length is non-zero, the source encoder is used to generate
an input count that "wraps-around" by the given length (modulus)
before it is used to generate a table index.
NOTE:
This only affects the internal PLS input count and that it
is still possible to generate table indexes outside of the
array boundaries. If the instantaneous changes are made
to the Encoder Register with the Encoder Reset, Encoder
Preload, or the Home Instruction. A generic PLS Reset
Instruction should be used to sync up the interim PLS
Register with the Encoder Register.
Calculating the mask value:
For AXIMA controller
Since the PLS function has the ability to control all of the outputs, a
mask is provided so the PLS can operate without interfering with
outputs controlled by other PLSs, PLCs or Programs. The same
formulas for calculating the array values can be used to calculate the
Mask value.
e.g. If the PLS is to control outputs 40 through 47, Mask = 2** (8)
+2** (9) +2** (10) + 2** (11) +2** (12) +2** (13) +2** (14) + 2** (15)=
65280. To use all enable all the outputs for a PLS the mask value
would be -1.
For AXIMA 2000/4000 controller
e.g. If the PLS is to control outputs 9 through 12 the mask value will
be Mask = 2** (9+3) + 2** (10+3) + 2** (11+3) + 2** (12+3) =2**12 +
2**13 + 2**14 + 2**15, Mask = 61440
Calculating the multiplier:
Multiplier = 1/(# encoder counts per array element)
See PLS Generic Instructions to customize the PLS for your
application with features such as:

118
•
PLS reset
•
Directing the PLS output to registers other the AXIMA outputs
•
Use registers other the encoder for a PLS source.
NOTE:
Keep in mind when using Generic Instructions the PLS
numbers are 0 through 7 as opposed the PLS Instruction
which uses the numbers 1 through 8.
NOTE:
The PLS is designed to track the encoder under normal
operating conditions. If a rotary value is used, the AXIMA
PLS logic checks the PLS register at each servo interrupt
to see if the rotary value has been exceeded. If it has, the
AXIMA subtracts the rotary value. If large instantaneous
changes are made to the encoder register in between
servo interrupts it may take a number subtractions to
catch up. In an extreme example, the encoder position
may be at 2** 31 and the Motion Program executes an
Encoder Preload Instruction to zero the encoder position.
The AXIMA will take several minutes to catch up. To avoid
this condition, if a rotary PLS function is used, the PLS
should first be turned “Off”, then execute an Encoder
Preload Instruction. Then, use a Generic Instruction
executing a PLS Reset. (see the AXIMA Generic
Instructions Reference Manual). Finally, the PLS can be
turned back on. This logic is usually programmed in the
Home Subroutine.
Print Instruction

Quick Move (Online) Dialog Box
For each axis the Movement Type is either Absolute or Incremental.
Absolute moves are specified by Position and does not include the
Movement Direction. Incremental moves are specified by distance
and direction.
The Velocity, Acceleration and Deceleration are included for
simplicity and are Coordinate System attributes. The operation of
these fields is the same as the Velocity, Acceleration and
Deceleration Instructions.
The initial values are retrieved from the controller. Upon closing this
dialog box the Acceleration, Deceleration and Velocity parameters are
set back to the initial values.
The Current Profiler Position list box shows the position (in user
units) of all axes in the Coordinate System. Initialized Global
Variables are provided to store these "learned" positions within the
122
Application. These variables can then be used within the Motion
Program.
To initialize a Global Variable, select an axes current position and
press the Init Global Var button or double click on the Axis list box
and a list of Global Variables is presented. Then selects the
appropriate variable to initialize and it is stored immediately.
Since the Application is online, the change to the Global Variable
initial values will be immediately transmitted to the controller as
well as changed in the Application. These changes may be stored on
disk by either pressing File Save or by selecting File Upload and then
File Save. File Upload retrieves the current value stored in the
initialized Global Variable within the controller.

Real Time Profile Instruction
Group:
Velocity
See Also:
External Time Profile Instruction
Description:
The main purpose of this instruction is to change from external time
base to real time base. It can also be used to set Acceleration,
Deceleration and S-Curve in instructions.
NOTE:
The program will wait on this instruction until the
previous move is complete (this is done to avoid
switching time bases in the middle of a external time base
move). This is only true if the Begin Using Real Time box
is checked.
125
When switching to real time from external time, you must program a
new Velocity, Acceleration and Deceleration values.
Figure 85
Real Time Profile Dialog Box
The Begin Using Real Time box must checked to switch from external
time to real time. A new Velocity, Acceleration and Deceleration must
also be programmed. It can be unchecked if this instruction is used
only to change Velocity, Acceleration or Deceleration values when
already in real time base mode. This parameter is only available with
A4 or later firmware.
The S-Curve value controls the slope of the acceleration versus time
profile. If the value is zero, the acceleration profile is rectangular.
or bottom by the current acceleration or deceleration. The normal
value for S-Curve is 4 to 8 times the acceleration value. A zero value

Target Velocity, Vector Velocity, Feedrate Override Instruction
Description:
This instruction sets the target velocity for all subsequent motion by
the profiler. This programmed velocity may be over-ridden by the
Feedrate Override Instruction. The velocity specified with this
instruction is a Coordinate System attribute. Therefore when
coordinating the motion of multiple axes the velocity of each
individual axis will be less than the target velocity. For more
information see the, “Understanding Motion in a Coordinate System”
section.

Registration Move Instruction
Group:
Feedback
See Also:
Description:
This command initiates a high-speed interruptable move. The
Registration Move sequence consists of an Initial Move (either
incremental or absolute) with a Registration Input Valid Window in
the middle of it. Within the capture window, an internal encoder
capture is initiated and monitored. If a capture occurs within the
window, the initial move is killed and the Registration Move is
started.
The components of the Registration Move Instruction are as follows:
The Movement Type can be either incremental (trailing forward
slash) or absolute.
127
The Movement Direction is used to start the incremental or
absolute move indicated by the axis designator. This move
drives the rest of the Registration Move sequence.
The Registration Move parameter is added to the encode
position when the Registration Input is detected within the
Registration Input Valid Window. In this case, this axis
Registration Captured flag is set, the move in progress is killed,
and the Registration Input is used as the starting reference for
the Registration Move Instruction.
The Registration Input Source parameters are dependent on
controller type and axis selected.
The optional Registration Input Valid Window “Window”
parameter defines the width of the capture window. If this
parameter is not present or is zero, the capture window is then
defined as the area between the start of the window and the end
of the move.
The optional Registration Input Valid Window "Start"
parameter defines the start of the capture window. If this
parameter is not present, the window begins at the start of the
move.
The optional Abort Bit parameter is a flag that is monitored
during the entire Registration Move Instruction sequence. If the
bit is seen, the current move is killed and the axis Registration
Aborted flag is set indicating a user abort condition.
Program flow will continue to the next instruction after the
Registration Move begins or after the end of the capture window has
been passed. If, however, the Abort Bit is being monitored, program
flow will continue only after the Initial Move ends, the Registration
Move ends, or the entire sequence is aborted.

Description:
This instruction will cause the programmed path to be rotated about
the given center point (identified by the position field for each axis).
The plane of rotation is defined by the primary and secondary axes.
This instruction requires two axes in a coordinate system.
The Rotation Angle specifies the number of degrees of rotation angle.
Positive rotation is defined as rotation from the primary to the
secondary axis. A negative rotation is also allowed. The rotation is
relative to the absolute Coordinate System. This instruction does not
by itself cause any motion.

Sinusoidal Move Instruction
Group:
Motion
See also:
Target Velocity, Vector Velocity, Vector Acceleration, Distance To
Go, Distance Into Move, Arc Move Instruction
Description:
This instruction generates a sinusoidal profile on the selected axes.
When executed on two axes at the same time, this instruction can be
used to generate circles or ellipses.
The sinusoidal movement for each axis is defined by the destination
in absolute user units, phase angle (in degrees), the sweep in number
of degrees (360 for one period), and the amplitude of the Sinusoidal
in user units.
133
Figure 94
Sinusoidal Motion Dialog Box
The Destination parameter is the final end point where a particular
axis will finish.
The Phase Angle parameter sets the direction of travel along the arc
segment (i.e., CW or CCW). This parameter relates to current
position at the start, which, in turn, correlates to position of a
sinusoidal wave form.
For example
To create CCW circular motion in a two axis system (X and Y), the X
Axis would leads the Y Axis by 90°. To create motion in the CW
direction, the Y Axis would lead the X by 90°.
The Sweep parameter determines the arc segment length.
The Amplitude parameter determines the amount of curvature.
Typically these values would be the same for any two axes generating
a circular arc segment. For a parabolic curve, the amplitude on each
axis would be different.
Sinusoidal Move Example:
The figure below graphically shows a circular move from (5,Ø) to
(5,Ø) with a 360° sweep, the table below shows the X and Y axis
values necessary to produce the desired motion. The amplitude and
phase angle of the sine wave plot directly correlates to the radius and
position on the circle.

Description:
This instruction sets the travel limits monitored by the within Travel
Limit A limit and/or not within travel limit B bits. There are two
types of Travel Limit (“A” and “B”). The “A” travel limit sets its bit on
when the axis is within its limits and “B” travel limit sets its bit when
the axis is outside its limits. For coordinate systems the bit(s) is set
if all of its axes are within their limits. This instruction overrides the
values set in the Axis Limits dialog box. If power cycled, the value
automatically reverts back to the value in the Axis Limits dialog box.

Description:
This instruction takes two logic blocks and connects them to the
given counter. The first block is connected to the count input and the
second block is connected to the reset input of the counter.
The Counter # value is limited to a range of 1 through 8.
The Counter # value decrements once on every rising edge of its clock
input until it reaches zero. Upon reaching zero the counter output
will be on. If the reset input of a counter is on, the counter value is
reset to its preset value and the counter output will be off. Rising
edge clock inputs are ignored while the reset input is on.
Counter Preset is the preset value of the counter is reset to this value
when the reset logic block is true.
143
Both the current Counter # value and Preload are retained in battery
backup memory during power down. The output of the counter will
also remain at the state that it was at prior to removal of power
(unless the reset line is on) when power is re-applied.
Counter Preload and Counter values are Pre-defined Variables and
can be monitored or changed by Motion or Auxiliary Programs if
desired.

The input choices are Contact, Timer, Counter or Latch. If the input
is a contact a contact name (variable name) is required, otherwise a
number is required for Timer, Counter and Latch.
All inputs are assumed to be N.O. (normally open).
The Not check box is used to invert the status for an N.C. (normally

AXIMA Reference ManTuning Procedures
Overview
While closed loop systems offer the highest performance, they must
be properly tuned to achieve this performance.
Tuning your AXIMA controller involves changing the constants used
in the servo loop computations. This is easily accomplished using the
AXIMA Software’s tuning tools. Select the tuning fork icon from the
toolbar or using the menu, Tools,Tune Drives or F9. The Tuning
dialog box has four tabs labeled Step 1 through Step 4. Step 1 is the
initial setup tab. Step 2 and 3 are for tuning the drives (one axis at a
time). Step 4 is used for tuning the AXIMA controller.
157
P/N 400290-00
Step 1 - Setup
The purpose of Step 1 is to select the axis to be tuned and to enter the
appropriate data to permit the tuning software to assist you during a
tuning session.
The data entered in Step 1 sets up the correct scaling for the graphs
ans is used to determine whether or not you can control the drive
enable using this software. It is also needed to calculate the initial
proportional and feedforward velocity gains used in Step 3 and Step
4. These initial gains will typically be 1/2 to 1/4 of the gains set up by
the AXIMA Defaults button in the servo dialog box. These lower gain
values are more forgiving of the mechanical backlash and drive train
torsional windup that are common in most systems.
Figure 109 Tuning Dialog Box: Step 1 - Setup
Select the Coordinate System and Axis you wish to tune by clicking
on the arrow buttons on the right side of the list boxes.
158
Tuning Procedures
Enter the appropriate Encoder Density. This line density is entered
in “lines per motor revolution”. If you are using linear motors, enter
the number of “lines per inch". The field will still display lines/motor
revolutions The encoder multiplier for that axis is used to convert the
line density to “counts/motor revolutions” for motors and “counts/
inch” for linear motors.
Make sure that the numbers entered correspond to the way the DIP
switches (LX drives) or parameters (MX and E Series drives) are
setup in the drive.
The motor/drive type, loop type (either velocity or torque) and the
encoder lines/motor revolutions are displayed in static fields. This
information is retrieved from the servo setup in the AXIMA.
The Maximum Velocity (in RPM’s) and the Maximum Voltage (in
volts) values need to be entered in the Command Scaling area for a
velocity mode drive. If torque mode is selected and the drive/motor
are unspecified, enter the continuous torque (lb.-in.) and Maximum
Voltage (volts). If torque mode is selected and the drive is either an E
Series or an MX or LX drive, these fields are grayed and no
information is required.
View Current AXIMA Gains Button
This option provides a convenient way to view the current AXIMA
gain values without having to exit the tuning procedure. The
information in this dialog box is for reference only and is not editable.
Initialize Gains/Original Gains Button
The Initialize Gains button calculates a reasonable starting value for
gains for the selected axis and sends the gains for the current axis to
the AXIMA controller. The gain values that are in the axis are saved
so they can be restored at any time during the session. Initialized
gains are a good starting point for system tuning. If your axis
becomes unstable when you click on the Apply Now button, click on
the Initialize Gains button to initialize the AXIMA gains. If the
unstable condition continues, it is most likely being caused by drive
tuning ans should be corrected before continuing.
After you click on this button it’s text will change to Original Gains.
Clicking on the Original Gains button will send down the gain values
that were originally in the AXIMA before entering the tuning session.
You can go back to the gains you started with at any time by clicking
159
on the Original Gains button. This button is grayed out (not active)
until you click on the Apply Now button.
Apply Now Button
Once the data has been set up for this axis and coordinate system,
and the Apply Now button is pushed, it will be retained through the
entire tuning session even if other axes are subsequently set up.
The Apply Now button also tests the enable line assignments ans
actually tests the output to determine if it can take software control
over the enable output. The enable output is determined by the
enable output data box in the Axis Servo dialog box seen during
AXIMA axis setup. If no assignment conflicts are detected the
software will attempt to enable the drive and if it is successful, the
drive will be enabled for about 1/2 second during the test. If the
software cannot enable it or suspects it cannot control the output,
AXIMA will display a message (see Figure 110) alerting you to this
fact and what your options are for proceeding.
If the drive becomes momentarily unstable during the enable test,
click on the Initialize Gains button. If it’s still unstable, adjust the
drive gains, not AXIMA gains, to stabilize it. Usually this will involve
reducing the drives proportional and possibly the derivative gain.
If you want the AXIMA Software to control the enabling and
disabling, and the enable test was successful, you can proceed to Step
2 if the axis is in velocity mode or Step 3 if the axis is in torque mode.
Enable/Disable Control Test
However, if you want the AXIMA Software to control enabling and
disabling, but you were unsuccessful in enabling the drive with the
Apply Now button, the following window will be visible. The enable
output is determined by the enable output data box in the Axis Servo
dialog box seen during AXIMA axis setup. You must make changes in
the external control or in your application to allow AXIMA Software
to take control. To permit software to take control once the enable,
you must not be controlling the setting or clearing of the drive enable
output from within your AXIMA Motion or PLC Programs. This can
be accomplished one of three ways.
160
Tuning Procedures
Figure 110 Enable Test Failure Prompt
The simplest method is to Halt All Programs by pushing the Halt All
Programs and Test button in the Enable Test Failure dialog box.
Choosing this will halt execution of all Motion, PLC and Auxiliary
Programs and will relinguish all control to the tuning software.
Another method is to choose the Halt Motion/PLC Program on Test
button. This will halt the Motion and PLC Programs only in the
selected coordinate system. This can be chosen if you need the
AXIMA to continue accepting another coordinate system to keep the
machine running while you tune the selected axis.
!
CAUTION
The Halt Motion/PLC Program should be chosen only if you are sure
that the running program will not affect the enable output and will not
restart the halted program.
The last method would be to rewrite your program to allow it to run
normally but still allow the tuning session to control the enable/
disable output. This is the least attractive of the choices because of
the inconvenience involved in rewriting a program and reassigning
outputs.
161
The Skip Test And Proceed button will put the drive under External
Enable/Disable control.This means that the software will not try to
enable or disable the drive during the remainder of the tuning
session and the Enable/Disable button will remain grayed in Steps 2
through 4. You will need to use some external means to enable and
disable the drive.
Step 2 - Adjust Offset
The purpose of Step 2 is to null the offset of an axis that is in velocity
mode. If the axis is being operated in torque mode, no offset
adjustment is required and the Open Servo Loop and Enable Axis
buttons are grayed. Move on to Step 3.
The drive must be enabled and the servo loop must be opened to
perform this adjustment. If the Enable button is grayed, you do not
have control over the enabling and disabling of the drive (see Step 1)
using the AXIMA Software. In this case, you are responsible for
enabling the drive externally to adjust the offset.
Figure 111 Tuning Dialog Box: Step 2 - Adjust Offset
162
Tuning Procedures
Open/Close Servo Loop Button
The Open/Close Servo Loop button opens and closes the servo loop
associated with the current axis. The analog command wires should
remain connected to the drive so that all components in the system
will be compensated for when adjusting the drive offset. This button
will be grayed if you have motion occurring due to a running Motion
Program and you choose not to stop this motion.
Enable/Disable Axis Button
This button enables and disables the current axis. If it is grayed, the
enabling and disabling of the axis is not being controlled by the
tuning session and must be externally controlled.
Display/Procedure
This option allows you to switch between viewing the procedure for
nulling the offset and the graph which displays the encoder position.
The graph can be expanded to fill the Tuning dialog box by clicking
on the Size button in the upper right corner of the graph.
Adjusting the Drive Offset
If the motor shaft drifts more than one revolution in 12 seconds the
offset must be adjusted. The graph window displays encoder position
as a function of time and is a very useful tool to determine when
drifting has stopped. The graph is scaled for 12 seconds horizontal
and ±.5 rev vertical.
The offset pot for the LX drive is located on the LX personality board
(see User’s Guide for the LX Brushless Servo Drives, P/N 400272-00,
for information). The offset for the MX drive can be adjusted with
Pr06 (see User’s Guide for the MX Brushless Servo Drives, P/N
400268-00, for more information).
The E Series drives are factory adjusted ans will normally need no
field offset adjustment. E Series drives offset is adjusted either with
the FM-P module or the PowerTools Software. If using the FM-P
module the analog input offset can be found in the analog group
parameter #9.02 AI zero off. If using PowerTools use Details View,
Analog Tab, Analog Zero Offset.
163
Step 3 - Drive Tuning
The purpose of Step 3 is to setup a test motion profile and, if the axis
is in velocity mode, tune the drive. If the drive is an LX, there are four
pots that need to be adjusted in this step. If the drive is an MX, one
pot and three MX parameters (Pr13, Pr14 and Pr15 - see User’s
Guide for the MX Brushless Servo Drives, P/N 400268-00) need to be
adjusted.
E Series drives will not require tuning for most applications up to
10:1 inertia mismatch. However, in application requiring maximum
performance, adjustment of the factory default tuning parameters
can be done with either the FM-P module mounted on the drive, or
with the PowerTools Base or Base Plus software, loaded onto a PC
with a serial port connection to the drive.
No drive adjustments are required if the axis is being operated in
torque mode. However, you must enter information in the edit fields
for the motion profile which will be used in Step 4 - AXIMA Tuning.
Figure 112 Tuning Dialog Box: Step 3 - Drive Tuning
164
Tuning Procedures
Setting up a Motion Profile
To setup a motion profile, choose a Motion Type and enter a Distance,
Velocity, Acceleration and Deceleration rates, and Dwell. Next, click
on the Apply Now button to accept the parameters you entered. Then
click on the Start Motion button to initiate motion on the axis. Each
of these motion profile parameters are explained below.
There are seven different motion types available (six are pre-defined
and the seventh option is the Motion Program of the Coordinate
System you choose in Step 1). Click on the arrow on the right side of
the Motion Type list box to select the desired motion type. The seven
motion types are described below:
The CW Then CCW Once option creates motion in the CW direction,
decelerates, then immediately creates that same motion in the CCW
direction. This option works exactly like CW Then CCW Repeated,
except that the axis will perform the motion only once each time you
click on the Start Motion button.
The CW Then CCW Repeated option creates repeated motion in the
CW direction, decelerates, then immediately creates that same
motion in the CCW direction and continuous to repeat until you click
on the Stop Motion button.
For example
If you entered a distance of ten revolutions, a velocity of ten
revolutions/second and no dwell. When you click on the Start Motion
button the axis will accelerate at the rate specified, move ten motor
revolutions at ten revolutions/second in the CW direction first. Then
decelerate to a stop at the decel rate specified then immediately
(unless you enter a Dwell) accelerates and performs the same motion
in the CCW direction. The axis will continue to run this motion
profile until you click on the Stop Motion button.
The CW Once option creates motion only in the CW direction. This
option works exactly like CW Repeated except that the axis will
perform the motion only once each time you click on the Start Motion
button.
The CW Repeated option creates motion only in the CW direction, and
after decelerating to a stop immediately repeats the motion (unless
you enter a dwell, in which case it will repeat the motion when the
dwell expires).
165
The CCW Once option creates motion only in the CCW direction. This
option works exactly like CCW Repeated except that the axis will
perform the motion only once each time you click on the Start Motion
button.
The CCW Repeated option creates motion only in the CCW direction,
and after decelerating to a stop immediately repeats the motion
(unless you enter a dwell, in which case it will repeat the motion
when the dwell expires).
The Motion Program option runs the Motion Program in the
Coordinate System that the axis currently being tuned is defined in.
When you select this option, the Distance, Velocity, Acceleration,
Deceleration and Dwell parameters will be grayed out.
Enter a Distance in user units. If you select CW and CCW Repeated
as a Motion Type, the motor will travel the distance you entered, first
in the CW, then in the CCW direction.
Enter a Velocity in user units/second2.
The Acceleration rate is in user units/second 2.
The Deceleration rate is in user units/second2.
Enter a Dwell in seconds. A dwell is only meaningful if you selected
a “Repeated” Motion Type. The axis will dwell for the amount of time
entered before repeating the motion profile.
The View Current AXIMA Gains button provides a convenient way to
view the current AXIMA gain values without having to exit the
tuning procedure. The information in this dialog box is for reference
only and is not editable.
The Open Loop Gains/Restore Gains button is used for sending gains
to the AXIMA. The Open Loop Gains are used during drive tuning.
The Restore Gains button sends down the gain values that were in
the AXIMA before doing this step. You can always go back to the
gains you had when you entered this step at any time by clicking on
the Restore Gains button.
A feedforward velocity gain and a very small proportional gain will
be calculated from the information provided in Step 1 and used to
simulate an open loop command signal to the drive. This will provide
some position loop control so the axis actually goes the distance
programmed.
166
Tuning Procedures
The Start/Stop Motion button is used to start and stop motion on the
current axis. When there is no motion the Start/Stop Motion button
will read Start Motion. After you click on it, it changes to Stop
Motion.
The Run/Halt Program button runs and halts the motion program
associated with the axis being tuned. The Start/Stop Motion button
changes to Run/Halt Program when you choose Motion Program as
a Motion Type (unless there is a run or halt conflicts) and select the
Apply Now button.
Display/Procedure
The Display/Procedure option allows you switch between viewing
the procedure for drive tuning and the graph options. There are three
graph options available to assist you in tuning your drive, they are:
Encoder Velocity and DAC Output, Encoder Velocity and Following
Error, and DAC Output and Following Error. The graph can be
expanded to fill the Tuning dialog box by clicking on the Size button
in the upper right corner of the graph.
Procedures for Drive Tuning
For All Types Of Drives
1. Choose one of the seven Motion Types you would like to use for
tuning. A suggested minimum velocity is 500 RPM. Fill in the
edit fields to define the characteristics of the profile (if you
select Motion Program the edit fields will be grayed out). Click
on the Apply Now button.
2. Enable the drive by clicking on the Enable Axis button. If it is
grayed, the enabling and disabling of the axis is not being
controlled by the AXIMA Software and must be externally set.
3. Click on the Open Loop Gains button to send down gains that
simulate an open position loop.
E Series Drive Tuning Procedure:
Initial drive setup with PowerTools use Advanced Mode Viewing.
167
1. Enter the reflected load inertia ratio into the inertia data box
(FM-P ). If you are not sure of your inertia, it is better to guess
low.
2. Enter the friction value into the Friction data box (FM-P ). To
determine the friction value, run the axis at a constant 100
RPM (this can be done easily in Step 3) and view the load
percent in the Status Tab (FM-P ). If this value varies, note the
lowest value seen here and enter it into the Friction data box.
3. Make sure high performance gain box is not checked in the
Motor Tab (FM-P ).
4. Now click the Analog Tab to verify the Input Command Voltage
(FM-P )
5. Now check the Motor Max Speed value in the Motor Tab to
verify it is correct (FM-P ).
6. Save all these parameters into the drive by clicking Memorize
button in PowerTools. If the Memorize button is grayed then use
the Update button.
7. The only adjustment left is the response also found on the Motor
Tab. This adjustment is made while watching the Motion
Graph. Increasing the response will tighten the system up.
8. Start the Motion Profile you have selected in Step 3 and monitor
the graph DAC output versus encoder feedback. These two
traces should overlay each other. If they do not, you may need to
make an adjustment to either the Analog Input Full Scale or
the Max Speed parameter in the E Series drive.
9. Run your profile, still with Open Loop Gains, and check the
ends of the accel/decel ramps of the encoder feedback trace. This
may be easier to see with the graph set to Encoder Feedback
versus Following Error. Adjust the E Series drive Response
parameter until you have optimized this (FM-P ).
168
Tuning Procedures
LX Drive Tuning Procedure:
1. Make sure the Accel/Decel pot is set fully CCW (factory default).
If the motor is unstable, turn the Gain pot and Response pot
CCW until it becomes stable.
2. Select graph of encoder velocity and DAC output. This will set
the scaling to that defined in Step 1 (example: 10V = 3000
RPM). Verify that the drive speed scaling switch in the LX (DIP
switch 1/1) is set properly.
3. While viewing the graph, adjust the Cal Speed pot so that the
constant speed portion of both graphs are on top of one another
and are actually constant.
NOTE:
The Cal Speed adjustment will be easiest to perform if the
profile has a constant velocity that is at least one second
long.
4. Increase the Gain until the encoder velocity graph matches well
with the DAC output graph. In particular, look for overshoot or
oscillation during the point in the profile that the speed changes
occur and listen for excessive noise or vibrations in the machine.
Too much Gain will cause instability.
5. Increase the Response pot to maintain a good match between
the two graphs. In particular, look for overshoot or oscillation
during the point in the profile that the speed changes occur and
listen for excessive noise or vibrations in the machine. Listen
for noise/vibration and oscillations in the velocity graph. If you
experience this, the Response is set too high.
MX Drive Tuning Procedure:
1. If the motor is unstable, set Pr13 and Pr14 lower than the
default values until it becomes stable.
2. Select graph of encoder velocity and DAC output. This will set
the scaling to that defined in Step 1 (example: 10V = 3000
RPM). Verify that the drive speed scaling switch in the MX is
set properly.
169
3. This will set the scaling to that defined in Step 1 (example: 10V
= 3000 RPM). Verify that Pr99 is set correctly for the
application.
4. While viewing the graph, adjust the Full Scale adjust pot
(access it from the front of the drive under the connections cover
between connection #8 and #9) so that the constant speed
portion of both graphs are on top of one another and are
actually constant.
NOTE:
The Cal Speed adjustment will be easiest to perform if the
profile has a constant velocity that is at least one second
long.
5. Increase Pr13 (Gain) until the encoder velocity graph matches
well with the DAC output graph. In particular, look for
overshoot or oscillation during the point in the profile that the
speed changes occur and listen for excessive noise or vibrations
in the machine. Too much Gain will cause instability.
6. Increase the Pr14 (Response) to maintain a good match between
the two graphs. In particular, look for overshoot or oscillation
during the point in the profile that the speed changes occur and
listen for excessive noise or vibrations in the machine. Listen
for noise/vibration and oscillations in the velocity graph. If you
experience this, Pr14 is set too high.
7. Adjust Pr15 only if there is more than a ten percent difference
between the two graphs (velocity error) for more than 100
milliseconds after a speed change. The default value, or a value
close to it, is satisfactory for most applications. Too much
integral gain will cause instability.
Step 4 - AXIMA Tuning
The profile that will be used for this step is actually entered in Step
3. Once this is done, click on the Initialize Gains button which
initializes the gains. For velocity mode; proportional and feed
forward velocity are initialized. In torque mode; proportional,
feedforward velocity, and derivative gain are initialized. These
values are calculated based on the data from Step 1.
170
Tuning Procedures
These initial gains are intended to provide stable motion with
reasonably good performance for most applications. In some
applications the proportional gain will need to be increased for
optimum performance
Figure 113 Tuning Dialog Box: Step 4 - AXIMA Tuning
The motion may be started by clicking on the Start Motion button (or
Run, if a Motion Program has been chosen in Step 3).
The Enable/Disable button allows you to enable and disable a drive.
The graph can display either; Encoder Velocity and DAC Output,
Encoder Velocity and Following Error, or DAC Output and Following
Error. If further optimized tuning is required, follow the procedures
below.
Velocity Mode Axis
Zero all the gains except proportional. The initial proportional gain
should be used as a starting point. Optimize the motion performance
171
by working on one gain at a time. The gains should be worked on in
the following order:
1.
2.
3.
4.
Proportional
Integral gain, integral delay, and integral limit
Feedforward velocity
Feedforward acceleration
Torque Mode Axis
Zero all the gains except proportional and derivative. The initial
proportional and derivative gains should be used as a starting point.
Optimize the motion performance by working on one gain at a time.
The gains should be worked on in the following order:
1.
2.
3.
4.
5.
Derivative
Proportional
Integral gain, integral delay, and integral limit
Feedforward velocity
Feedforward acceleration
Typically, the optimization process is an iterative one whereby the
value of the gain is increased and indicators of performance such as
velocity profile, following error, sound and vibration of the mechanics
are observed and used to determine when the gain is set right.
The derivative, proportional, and integral gains are determined
interactively by increasing the gain until performance is no longer
improved. The feedforward gains are calculated with the following
equations:
FFVEL = (PG)(ERROR)/VEL
FFACC = (PG)(ERROR)/ACCEL
Where:
PG (proportional gain) = Volts/Pulse
ERROR (following error) = Pulses
VEL (axis velocity) = Pulses/Seconds
ACCEL (axis acceleration) = Pulses/Second2

Diagnostics are provided for Online Applications only. To begin an
online session, select either File,Online or the Online button on the
toolbar. Diagnostics are provided are various levels of the Application
hierarchy (Application, Coordinate System, Axis and Programs).
To use the diagnostics select, the level of the application you wish to
diagnose in the hierarchy view to select Application, Coordinate
System, Axis, or Program, then select Tools,Diagnostics or the
Diagnostics button on the toolbar.
Application Diagnostics
The left side of the Application Diagnostic dialog box shows the
status of the digital inputs and outputs. The right side of the box
displays the Encoder Position, Encoder Velocity and Output Volts of
each axis of your system. Below the inputs and outputs is the status
of the various DC voltages used by the AXIMA controller.
To view the status of the expanded inputs and outputs use the
Selection list box. An input or output is on (active) if its associated
radio button is filled. These radio buttons are not selectable they
simply show I/O status, either “On” or “Off”.

174
Coordinate System Diagnostics
The left side of the Coordinate System Diagnostics shows the status
of various pre-defined bit values (for more information see
Coordinate System floating points and bits variables). The right side
show a list of analog values related to the Coordinate System.
Two choices of analog values may be selected by pressing the Next
button on the dialog box. The two choices of analog values are Vector
and Tracking. The vector values define the vectored motion,
including velocity, acceleration and length. The Tracking values
define the motion as it is in progress, including distance to go,
feedrate override and fraction into move.
Figure 115 Coordinate System Diagnostics Dialog Box
175
Axis Diagnostics
The left side of the Axis Diagnostics shows the status of various predefined bit values (for more information see Coordinate System
floating point and bit variables). The right side show a list of analog
values related to the Axis. The list of analog values may be selected
by pressing the Next button on the dialog box (lower right).
There are four choices of analog values Position, PID, Jog and Drive
I/O. The position values define the position (both commanded and
actual) in user units. The PID values define the voltage output
generated by each of the PID terms. The Jog values define the jog
motion as it is in progress, including velocity, acceleration and
deceleration.

Program Diagnostics
The Program Diagnostics shows the status of the program selected in
the hierarchy view. The diagnostic data provided is the same for all
type of programs including; Motion, Auxiliary and PLC. The data
includes the running/halted status, dwelling, inhibited and run/halt
request bits. For more information see Pre-defined Variable
Definitions.

Program Control
The Program Control dialog box is displayed when the Application is
online and program control is selected from the Tools menu or from
the icon on the toolbar. You can control the execution (start/stop) of
the Motion, Auxiliary and PLC Programs, issue immediate mode
instructions, view error messages and the status of program outputs.
Program Control with PLC Programs
The PLC Programs are a special case for this feature. PLC Programs
execute at the servo update rate and provide very high performance
processing. Therefore, due to the PLC Program design, the Pause,
Continue, Where Am I?, Single Step and Immediate buttons will be
grayed.

178
Select
The Select combo box at the top of this dialog allows you to select any
program contained by the application. Once you select a program it
will be displayed in the program list box along the status (running,
halted, dwelling, waiting).
Monitor Program
The Monitor Program check box displays output messages from the
program in the small list box including error messages and Print
Instructions.
Run Button
The Run button causes the program to begin execution from the first
instruction in the program.
Halt Button
The Halt button is used to stop the execution of the currently selected
program. When you press the Halt button the instruction that the
program was executing when the halt was requested will be
highlighted. Motion generated by the profiler will stop with zero
deceleration.
Pause Button
The Pause button causes the program execution to be stopped on the
current instruction. If their is motion in progress (generated by the
motion profiler) the Pause button will cause the motion to decelerate
to a stop. When you press the Pause button the instruction that the
program was executing when the pause was requested will be
highlighted.
Continue Button
The Continue button resumes program execution after the program
is stopped by the user with the Pause button. Any remaining motion
interrupted by the pause will be completed when you press the
Continue button.
179
Where Am I? Button
The Where Am I? button is used to update the current instruction the
program list will be updated to show the instruction in the list box.
The Halt, Pause and Single Step buttons will automatically execute
the Where Am I? feature to show you the current execution location.
The Where Am I? button matches the AXIMA program counter up
with the AXIMA instruction. The program counter points to the
generic instruction that was just executed. AXIMA instructions
normally are implemented with a single generic instruction, but in
some cases it takes multiple generic instructions. In the cases of
multiple generic instructions it may take several single steps to get
through an AXIMA instruction.
The program counter is not updated until the generic instruction has
been queued for execution. Therefore, in some cases, the program
counter update is delayed. The program control is polling AXIMA in
a time loop for the program counter and matching the AXIMA
instruction. Therefore you may see the Where Am I? update delayed.
Single Step Button
The Single Step button is used to step one instruction at a time
through the program. The current executing instruction will be
highlighted and will be visible within the list box at all times.
Variables Button
The Variables button will display the Variable Diagnostics dialog
box. This dialog allows you to view the contents of up to eight user
variables. Which can be a useful tool when diagnosing problems in a
program.
180
You can modify the contents of a variable by highlighting a variable
then selecting the Modify button.
Figure 119 Variables Diagnostics Dialog Box
Modify Button
The Modify button (on the Modify Variable dialog box) displays the
Modify Variable dialog box shown below. This dialog box allow you to
view the contents and/or modify a single variable at a time.

181
The New Value and New State controls will initially be grayed when
this dialog box is displayed. When you press the Modify button it will
change to an Update button and the New Value and New State will
be enabled. After changing the value or state you then press the
Update button which causes the variable contents to be updated.
NOTE:
Input status cannot be modified. If the program is writing
or setting the variables the program will overwrite the
value so you may not be able to modify it from this dialog
box.
References Button
The References button is used to find all references to the variable
selected. Note that variable references are available only in the
programs that have been uploaded.
Diagnostics Button
The Diagnostics button displays the Program Diagnostics dialog box.

Immediate Button
The Immediate button displays the Immediate Instructions dialog
box. Some instructions (commands) may be ignored if the selected
program is running
The Immediate Instructions list box displays a list of all available
immediate instructions. To send an immediate instruction to a
selected program, double click on the desired instruction. Most
instruction dialog boxes will require you to enter a parameter or
value. When you select OK from the instruction dialog box the
instruction is immediately sent to the controller.
Use CAUTION when issuing immediate instructions since they may
affect the motion immediately.

203
P/N 400290-00
Symptom
Possible Cause
Motor jumps on power up.
1.) Be sure a Encoder Match Instruction or Encoder
Match Request bit is set prior to enabling the
amplifier.
2.) With the amplifier disconnected;
A.) Adjust amplifier offset for no motor motion
with zero volts at the input. See the
appropriate LX/MX manual.
B.) Adjust DAC offset for zero volts output from
AXIMA when zero volts is commanded.
Output LED's do not come “On”.
1.) Check 24 VDC power supply at the AXIMA
controller terminals.
2.) Use the Application diagnostics to check the
status of the I/O power supplies and output
status.
3.) Check 24 VDC fuse on AXIMA interface and
controller boards.
4.) Halt all programs including PLC programs, then
use Program Control mode to set the output.
This will determine if multitasking programs
are fighting for control of the output.
5.) Check ribbon cable connections between the
AXIMA interface and controller boards.
Output LED is “On” but output is “Off”.
1.) Output are sinking only. Measure the voltage
from the output to the +24 volt supply.

3.) Be sure either Encoder Preload or Encoder
Match Instruction is executed before the
amplifiers are enabled.
4.) With the drive disabled, check the command
output with no motion commanded in the
Application Diagnostics dialog box. Also,
measure the voltage at the terminals.
5.) Check for proper phasing of encoder. Disable the
drive, select positive polarity on the Axis
Parameter dialog box, select Application
Diagnostics (you must be online).
As the motor shaft rotates CW (as viewed from the
shaft end), the encoder position should count up
and the command output should go negative as
displayed on the screen.
Motor is unstable or overshoots when
positioning.
If the motor is controlled by an LX drive see LX
Tuning. If controlled by an MX drive see MX
Tuning. Also, unsuitability can be caused by

Floating Point
Pre-defined Floating Point Variables related to the coordinate
system.
Distance Into Move
FP
r
The Distance Into Move is the vector distance that has been
completed. The units are in user units for the axes involved in the
move.
Distance Into Path
FP
r
The Distance Into Path value is equal to the Total Distance minus
the Distance To Go. This variable is for user information only and is
not used by the DSP for motion calculations.
Distance Squared
FP
r
The square of the vector distance. The units are in user units for all
axes in motion, squared.
Distance To Go
FP
r/w
The vector distance remaining in the current move. The units are in
user units for all axes in motion, squared.
218
Feedrate Override
FP
r/w
The Feedrate Override value is multiplied by the programmed
velocity to determine the target velocity. If Feedrate Override
variable is changed during a move the motion will immediately
acceleration or deceleration using the acceleration or deceleration
and S-Curve rates.
Fraction Into Move
FP
r
The fraction into the move is equal to the distance into move divided
by the vector length.
Manual Vector
FP
r/w
Allows a manual adjustment of the vector length to override the
automatic vector length calculations. This is used for applications
where velocities other than the calculated vector velocity is desired.
This Pre-defined Variable does not affect the length of the move of
any axis.
Target Velocity
FP
r
The vector velocity is the result of the programmed velocity
multiplied by the feedrate override. This Pre-defined Variable is
modified by the Velocity Instruction.
Total Distance
FP
r/w
This value is equal to the sum of the current, plus all of the previous
vector lengths.
For example; if Move #1 vector length is 10 inches and Move #2 is 15
inches, the Total Distance is updated to 25 inches at the beginning of
Move #2.
This variable is for user information only and is not used by the DSP
for motion calculations. The Total Distance can be set to a value
using the Formula Instruction.

The units are units/sec/sec for all axes in motion. The value is
dynamic during any motion.
Vector Length
FP
r
The resultant vector length of all the axes in the current move. Vector
length equals distance into move plus distance to go in user units.
This vector length is equal to either the automatic vector calculation
(controlled by the Automatic Vector Instruction or the Manual Vector
Instruction).
Vector Velocity
FP
r
The current vectored velocity of all the axes in the current move. This
value will increase during acceleration up to the target velocity and
decrease during deceleration. The units are in user units/second for
the axes involved in the move.
Velocity Squared
FP
r
The square of the current vector velocity. The units are in user units/
second for the axes involved in the move.
220

AXIMA Reference ManPre-defined Variable
Generic Identifiers
Overview
When using generic parameter and bit references, care should be
taken to determine the correct axis and coordinate system reference
numbers. Notice that coordinate system and axis numbers range
from 0 to 7 and program numbers range from 0 through 14. The
AXIMA Software assigns numbers in the order they are created.
Since you can assign any encoder and DAC number to an axis, the
axis numbers (0 to 7) do not necessarily correspond directly to the
axis connector numbers (1 to 8).
To determine the generic parameter reference number, select the
Advanced option from the Options menu then print out your
Application. The reference numbers for user variables can also be
found in the Variable dialog box after selecting the Advanced option.
