General
safety
in conformity
and Operating
Instructions
with the Low-Voltage
1. General
In operation, drive converters, depending on their
degree of protection, may have live, uninsulated,
and
possibly also moving or rotating parts, as well as hot
surfaces.
In case of inadmissible
removal of the required covers,
or improper use, wrong installation or maloperation,
there is the danger of serious personal injury and
damage to property. For further information, see
documentation.
All operations serving transport, installation and
commissioning
as well as maintenance
are to be carried
out by skilled technical personnel. (Observe IEC 364 or
CELEC HD 384 or DIN VDE 0100 and IEC 664 or
DINNDE 0110 and national accident prevention rules!)
For the purposes of these basic safety instructions,
“skilled technical personnel”
means persons who are
familiar with the installation, mounting, commissioning
and operation of the product and have the qualifications
needed for the performance of their functions.
2. Intended
use
Drlve converters are components
designed for inclusion
in electrical installations or machinery.
In case of installation in machinery, commissioning
of
the drive converter (i.e. the starting of normal operation)
is prohibited until the machinery has been proved to
conform to the provisions of the Directive 89/392/EEC
(Machinery Safety Directive - MSD). Account is to be
taken of EN 60204.
Commissioning
(i.e. the starting of normal operation) is
admissible only where conformity with the EMC
Directive (89/336/EEC)
has been established.The
drive
converters meet the requirements
of the Low-Voltage
Directive 73/23/EEC. They are subject to the
harmonized
standards of the series prEN 50178/DIN
VDE 0160 in conjunction with EN 50439-1NDE
0660,
part 500, and EN 60146lVDE
0558.
The technical data as well as information concerning the
supply conditions shall be taken from the rating plate
and from the documentation
and shall be strictly
observed.
3. Transport,
storage
The instructions for transport, storage and proper use
shall be complied with.
The climatic conditions shall be in conformity with prEN
50178.
for drive converters
Directive
4. lnstallatlon
The installation and cooling of the appliances shall be in
accordance with the specifications
in the pertinent
documentation.
The drive converters shall be protected against
excessive strains. In particular, no components
must be
bent or isolating distances altered in the course of
transportation
or handling. No cantact shall be made
with electronic components
and contacts. Drive
converters contain electrostatic sensitive components
which are liable to damage through improper use.
Electric components must not be mechanically damaged
or destroyed (potential health risks).
5. Electrlcal
connectlon
When working on live drlve converters, the applicable
national accident prevention rules (e.g. VB 4) must be
complied with.
The electrical installation shall be carried out in
accordance with the relevant requirements
(e.g. cross
sectlonal areas of conductors, fusing, PE connection).
For further information, see documentation.
Instructions for the installation in accordance with the
EMC requirements,
like screening, earthing, location of
filters and wiring, are contained in the drive converter
documentation.
They must always be complied with,
also for drive converters bearing a CE marking.
Observance of the limit values required by EMC law is
the responsibility of the manufacturer
of the installation
or machine.
6. Operation
Installations, which include drive converters shall be
equipped with additional control and protective devices
in accordance with the relevant applicable safety
requirements,
e.g. Act respecting technical equipment,
accident prevention rules, etc. Changes to the drive
converters by means of the operating software are
admissible.
After disconnection
of the drive converter from the
voltage supply, live applicance parts and power
terminals must not be touched immediately because of
possibly energized capacitors. In this respect, the
corresponding
signs and markings on the drive
converter must be respected.
During operation,
closed.
all covers and doors shall be kept

Operating Instructions

2.4
-
Application as directed
The 8200 series consists of electrical devices which are designed
for application in industrial power installations.
The controllers are directed
-
as components for the control of variable Speed drives with
AC motors
-
for the installation into control cabinets or control boxes
-
as controllers for the installation of drive Systems
The controllers comply with the protection requirements of the
EC Low-Voltage Directive.
Drive Systems with 8600 controllers which are assembled
according to the requirements for CE-typical drive Systems (see
chapter 4.2.2) comply with the EC EMC Directive.
The CE-typical drive Systems with the 8600 controllers are
intended
-
-
for the Operation at public and non-public mains
-
for the application in industrial, commercial and residential
areas
The CE-typical drive Systems are not suited for the connection
to IT mains (mains without earth-potential reference) because of
the earth-potential reference of the RFI filter.
The controllers are not appliances but directed as components
to be assembled into drive Systems for industrial use.
The controllers themselves do not form machines for the
purpose of the EC Machinery Directive.

2.5
CE conformity
What is the purpose of EC directives?
EC directives are issued by the European Council and are intended
for the determination of common technical requirements
(harmonization) and cet-tification procedures within the European
Community. At the moment, there are 21 EC directives of product
ranges. The directives are or will be conver-ted to national laws of
the member states. A certification issued by one member state is
valid automatically without any fut-ther approval in all other member
states.
The texts of the directives are restricted to the essential
requirements. Technical details are or will be determined by
European harmonized Standards.
What does the CE mark imply?
After a verification, the conformity to the EC directives is certified by
affixing a CE mark. Within the EC there are no commercial barriers
for a product with the CE mark. The enclosure of a conformity
cet-tification is not necessary according to most directives.
Therefore, the customer is not able to appreciate which of the 21
EC directives applies to a product and which harmonized Standards
are considered in the conformity verification.
A drive controller with the CE mark itself corresponds exclusively to
the Low-Voltage Directive. For the compliance with the EMC
Directive only general recommendations have been issued so far.
The CE conformity of the installed machine remains the
responsibility of the User. For the installation of CE-typical drive
Systems (see page 26ff), Lenze has already proved the CE
conformity to the EMC Directive.
What is the aim of the EMC Directive?
The EC Directive relating to Electromagnetit Compatibility is
effective for “equipment” which may either Cause electromagnetic
disturbances or be affected by such disturbances.
The aim is the limitation of the generation of electromagnetic
disturbances so that the Operation of radio and telecommunication
Systems and other equipment is possible and that a suitable
immunity of the equipment against electromagnetic disturbances is
ensured so that the Operation tan be achieved.
What is the objective
of the Low-Voltage Directive?
The Low-Voltage Directive is effective for all electrical equipment
for use with a rated voltage between 50V and 1 OOOV AC and
between 75 and 1500V DC and under normal ambient conditions.
The use of e.g. electrical equipment in explosive atmospheres and

Handling
4.1
Mechanical installation
These frequency controllers must only be used as built-in
units.
Install the controller vettically with the terminal Strips at the
bottom.
Allow a free space of 100mm at the top and bottom. For the
controllers 8612 . . . 8615 this free space must also be allowed
at both sides. Ensure unimpeded Ventilation of cooling air.
If the cooling air contains pollutants (dust, flakes,
grease,aggressive gases ), which may impair the controller
functions, suitable preventive measures must be taken, e.g.
separate air duct, installation of a fiter, regular cleaning, etc.
If the controller is permanently subjected to Vibration or
shaking, shock absorbers may be necessary.

Electrical installation
The Controllers contain sensitive electrostatic compontents.
Priior to assembly and Service operations in the area of the
controller connections, the Personne1 must be free of
electrostatic Charge.
These persons tan discharge themselves by touching the PE
fixing screw or another grounded metal part in the control
cabinet.
All control inputs and Outputs of the controller are mainsisolated. The mains isolation has a basic insulation. The control
inputs and Outputs must be integrated into another level of
protection against direct contact.
Use insulated operating elements, connect the mechanical
screw fastener of the setpoint potentiomenter (accessory kit)
with PE.
Unused control inputs and Outputs must be protected with plugs
or the covers included in the delivery.
When using current-operated protective equitpment:
- The controllers are internally equipped with a mains rectifier.
As result, a DC-fault current may prevent the tripping of the
current-operated protective equipment after a short-circuit to
frame.
Therefore, we recommend additional measures such as
protective multiple earthing or universal-current sensitive
current-operated e.1.c.b.
- When dimensioning the tripping current of current-operated
e.1.c.b. please observe, that the capacitive leakage currents
between cable screens and RFI filters may result in false
tripping.
l
l
l
l
l
The regulations about the minimum Cross section of PE
conductors must be observed. The Cross-section of the PE
conductor must be at least as large as the Cross section of the
cable connection.
In the case of condensation, only connect the Controller vwhen
visible moisture has evaporated.
Before first switching-on of the controller check whether there is
an earth fault at the output side, if so, remove it. Earth faults
which occur during Operation will be detected, the controller will
be switched off and indicate the fault message “OCl”.
The internal current limitation tan be overloaded when
connecting or disconnecting the controller very often. With cyclic
mains connection, the Controller tan be switched on every 3
minutes.
Replace defective fuses only with the specified type and when
no voltage is applied.
The controller remains live for up to 3 minutes after mains
disconnection.

4.2.1 Motor protection
The units do not have a full motor protection.
For monitoring the motor temperature PTCs orthermal contacts
tan be used.
The connection possibilities are shown on page 28.
-
When using group drives, a motor protection relay is required for
each motor.
When using motors which do not have a suitable insulation for
controller Operation:
- Connect motor filters for protection (see page 45).
Please contact your motor manufacturer.
Please note:
These frequency controllers generate an output frequency of up to
480 Hz when set correspondingly. The connection of a motor which
is not suitable for this frequency may result in a hazardous
overspeed.
4.2.2 Installation in compliance with EMC
l
Lenze has built up typical drives with these controllers and has
verified the conformity. In the following this System is called
“CE-typical drive system”.
If you observe the pat-tially easy measures for the installation of
CE-typical drive System, the controller will not Cause any EMC
Problems and you tan be sure to comply with the EMC
Directive.
l
The following configurations tan now be selected by the User:
- The user himself tan determine the System components and
their integration into the drive System and is then held
responsible for the conformity of the drive.
- The user tan select the CE-typical drive System for which
the manufacturer has already proved the conformity.
For deviating installations, e.g.
- use of unscreened cables,
- use of group filters instead of the assigned RFI filters,
- without mains Choke
the conformity to the CE-EMC Directives requires a check of the
machine or System regarding the EMC limit values.
The user of the machine is responsible for the compliance
with the EMC Directive.

4.2.3 CE-typical drive System
-
-
Components of the CE-typical drive sytem
Controller, RFI filter and mains Choke are mounted on one
assembly board.
The System components are functionally wired according to the
chapter 5, section: Planning of the Operating Instructions.
Installation of CE-typical drive Systems
The electromagnetic compatibility of a machine depends on the
method and accuracy of the installation. Special care must be
taken of:
l
l
l
filters,
screens and
grounding.
Filters
Only use suitable mains filters and mains Chokes.
Mains filters reduce impermissible high-frequency disturbances to a
perrnissible value.
Mains Chokes reduce low-frequency disturbances, especially those
caused by long motor cables.
Motor cables which are longer than 50 m must be protected
additionally (motor filter or sine filter).
Screens
All cables from and to t3e controller must be screened.
Lenze System cables meet these requirements.
Ensure that the motor cable is laid separately from the other cables
(Signal cables and mains cables). Mains input and motor output
must not be connected to one terminal Strip.
Lay cables as close as possible to the reference potential. Dangling
cables are like antennas.
Grounding
Ground all metall-conductive components (controllers, mains filters,
mains Chokes) using suitable cables from a central Point (PE bar).
Maintain the min. Cross sections prescribed in the safety
regulations. For EMC, the surface of the contact is important, not
the Cross section.

Installation
l
9
l
Connect the Controller, mains fitter, and mains Choke to the
grounded mounting plate. Zinc-coated mounting plates allow a
permanent contact. If the mounting plates are painted, the paint
must be removed in every case.
-
When using several mounting plates they must be connected
with as large surface as possible (e-g. using topper bands).
Connect the Screen of the motor cable to the Screen connection
of the Controller and to the mounting plate of a surface as large
as possible. We recommend to use ground clamps on bare
metal mounting surfaces to connect the Screen to the mounting
plate with as large surface as possible,
screened cable
urface
If contactors, motor protection switches or terminals are located
in the motor cable, the screens of the connected cables must
also be connected to the mounting plate with as [arge surface
as possible.
PE and the Screen should be connected in the motorterminal
box. Metal cable glands at the motor terminaJ box ensure a
connection of the Screen and the motor housing with as large a
surface as possible.
If the mains cable between mains filter and Controller is longer
than 0.3 m, the cable must be screened. Connect the Screen of
the mains cable directly to the Controller moduie and to the
mains filter and connect it to the mounting plate with as large as
possible surface.
When using a brake resistor, the Screen of the brake resistor
cable must be directly connected to the controller and the brake
resistor and it must be connected to the mounting platte with a
surface as large as possible.
The control cables must be screened. Digital contra1 cables
must be screened at both ends. Connect the screens of the
contra! cables to the Screen connections of the Controllers
leaving as little unscreened cable as possible.
When using the Controllers in residential areas an additional
screening with a damping of Z 10 dß is required to limit the
noise emission. This is usually achieved by installation into
enclosed, grounded conrol cabinets or boxes made of metal.
Please note:
l
26
If units, which do not comply with the noise immunity EN 50082.
2 required by the CE, are operated next to the Controllers, an
electromagnetic interference of these units is possible.

4.2.4 Switching on the motor side
Switching on the motor side is permissible for an emergency stop

Please note that when switched with the controller enabled, this
may Cause the fault message OCl (shott circuitiearth fault). For
long motor cables, the fault current on the interfering cable
capacitances tan become so large that the short circuit monitoring
of the device is triggered. In these cases, a motor filter is necessary
to reduce the fault currents (See page 45).

5.4 Screenings
-
Cable screenings increase the noise immunity of the drive System
and reduce the interfering radiation.
The power and control terminals of the controllers are noise
immune without screened cables up to severity class 4 to
IEC 801-4. Burst of 4kV on the power terminals and 2kV on the
control terminals are permissible.
Screenings are only required when you want to operate the
controller in environments, where severity class 4 is not sufficient.
If your drive corresponds to the CE-typical drive System and you do
not want to carry out the radio-interference measurements
necessary for the conformity, screened cables are required.
5.5
Grounding of control electronics
The grounding of the control electronics is to ensure that the
potential of the control electronics does not exceed 50V to PE
(housing).
Single drives
Bridge the control terminals GND and PE.
Network of several drives
Avoid GND loops. Lead all GND cables to external, insulated
central Points, centralize again from there and connect to PE in the
central supply.
Make Sure that the grounding of the control electronics does not
darnage any external devices.

Accessories
Accessories are not included in the scope of supply.
6.1
Wake resistors
In the generator mode, e.g. when decelerating the drive, the
machine returns energy to the DC bus of the controller. If large
inertias are braked and/or short deceleration times are set, the DC
bus voltage may exceed its maximum permissible value. In the
case of overvoltage in the DC bus, the controller sets pulse inhibit
and indicates “overvoltage “. The controller cancels the pulse inhibit
once the votlage has returned to the permissible range.
To avoid overvoltage during braking, a brake chopper is used,
which switches an external brake resistor when the voltage in the
DC bus exceeds 765 V.
The absorbed energy is dissipated as heat so that the voltage in
the DC bus does not rise further.
l

The brake chopper is already included in the Standard
controller.
The suitable brake chopper is available as an Option. It is
connected to the terminals BR1 and BR2
(see connecting diagram, page 28).

Mains Chokes
Advantages of using a mains Choke:
l
l
l
l
Less mains disturbance
The wave shape of the mains current approaches sinusoidal; at
the same time the r.m.s. current is reduced by up to 40%
(reduction of the mains load, the cable load and the fuse load).
Increased life of the Controller
A mains Choke reduces the AC load of the DC bus capacitors
and thus doubles its Service life.
The transient high-energy overvoltages which are sometimes
generated at the mains side by circuit breakers or fuses are
stopped by the mains Choke and thus the units are usually not
damaged.
-
Low-frequent radio interference tan be reduced.
Please note:
l
l
42
When a mains Choke is used, the maximum possible output
voltage does not resch the value of the mains voltage.
- typicat voltage drop at the rated Point: 4 to 5%.
Mains Chokes are always required when the Controller is
operated with increased or maximum power.

6.3 Motor filter
.-.
Advantages of using a motor filter:
.
l
The motor filter reduces capacitive currents caused by parasitic
cable capacitances.
The slope of the motor voltage (dv/dt) is limited to 500 V/ps.
Motorfilters are always required for:
l
unscreened cables langer than 1 OOm.
l
screened cables longer than 50m.
o
when using motors which do not have suitable insulation for
controller Operation. (Observe data of the motor manufacturer.)
Please note:
Install the motor filter as close as possible to the controller
- Maximum cable length 5 m
Connect +!JG and -!JG of the motor filter only to the controller
terminals of the same designation.
Select the control mode “V/f-characteristic control”
(CO06 = -0-). The control “magnetizing-current control” is not
permissible.
The chopper frequency must be 4 kHz.
The max. permissible output frequency is 300 Hz.
The controller is loaded in addition to the motor current with
approx. 12% of the rated filter current.
The voltage drop across the motor filter at rated current and
rated frequency (fd = 50 Hz) is 2 to 3% of the controller output
voltage.
For motor cable lengths > 100 m (screened) and z- 200 m (unscreened) a sine filter should be used.
With unscreened motor cables it should be tested whether the
System camplies with the interference levels required for the
CE-EMC conformity.

RFI filters
6.6
Advantage of using a RFI filter:
Reduction of high-frequent radio interference.
l
Please note:
Because of the generation of leakage currents, the RFI filters
must be connected to earth. The RFI filter must always be
connected to earth at first even if you only want to test the
System.
Otherwise, the System is not protected against shock.
l
l
The filters listed in the following tan be connected to the 400 V
mains.
If you need filters for mains voltages of 460 V or 480 V, please

Which settings are necessary for the drive to operate?
After mains connection the controller is ready to operate after
approx. 0.5 seconds.
The frequency controllers are factory-set such that a four-pole
Standard motor with 400V rated voltage and 50Hz according to the
combinations in section 3.1 tan be operated without further
settings.
In case of motor ratings according to section 3.2 or 3.3, page 17ff,
it is necessary to increase the permanent output power
accordingly. Using the Codes Cl 19 and Cl 20 the output current
monitoring must be set to increased power or maximum power (see
page 99). The ICI setpoint (CO20) must also be adapted to the motor
(see page72).

Basic Parameter setting
Programming of the frequency controller enables the drive to be
adapted to your application. The possible settings are arranged in
Codes, which are numbered in ascending Order and statt with the
letter “C”. Esch code provides one Parameter which tan be
selected according to the application.
Parameters tan be absolute or relative values of a physical unit
(e.g. 50Hz or 50% related to fdmax) or numerical Codes giving
certain Status information (e.g. -O- = controller inhibited, -1controller enabled).
In cases where the Parameters represent values of physical units,
it is possible that the increment varies.
Example: The maximum field frequency tan be set in increments
of 0.1 Hz up to 1 OOHz, and in increments of 1 Hz from 1 OOHz
upwards.
In some Codes, Parameters tan only be read but not changed.
In the factory setting, only those Codes are displayed which are
necessary for the most common applications. For activation of the
extended code set see page 100.
2.1
Changing Parameters
Esch code has a factory set Parameter which tan be changed.
There are three different ways of selecting another Parameter,
depending on the Code:
Direct acceptance
The controller immediately accepts the new Parameter, i.e. while
you Change it using the UP or DOWN keys. This is possible even
when the drive is running.
Parameters which are immediately accepted are marked with ONLINE in the following programming tables.
Example:
Under CO50, the controller Shows the momentary field frequency in
Hz. You want to set a maximum field frequency (CO1 1) of 60Hz.

Acceptance with SH + PRG
The controller accepts a new Parameter when SH+PRG are
pressed. This is possible even when the drive is running.
First press SH and then in addition PRG. The display Shows --ok-for 0.5 seconds. The controller now works with the new Parameter.
The key combination SH and PRG tan be compared to the “return”
key on your Computer keyboard.
If yolu have to set a Parameter in this way, the programming tables
show the Symbol SH + PRG.
-
Acceptance with SH + PRG with controller inhibit
The controller accepts the new Parameter when the controller has
been inhibited before pressing SH + PRG.
Inhibit the controller, e.g. by pressing STP.
First press SH and than in addition PRG. The display Shows --ok-for 0.5 seconds. The controller works with the new Parameter
when controller inhibit is cancelled.
If you have to set a Parameter in this way, the programming tables
show the Symbol [SH + PRG].

2.1 .l Parameter setting by two Codes
Some Parameters are set by two Codes. A preselection code is
used to select the Parameter which is to be changed. The
Parameter is then changed by another Code. For example, to set
the JOG frequency JOG3, first set the preselection code CO38 to
-3- and then set the desired frequency for JOG3 via code C039.
2.2
Save Parameters
After the acceptance, new Parameters are saved in the RAM until
the controller is connected to mains voltage.
If you want to permanently save your settings, process as follows:
. Select code CO03.
l
l
Select -l-, i.e. Parameter set 1.
First press SH and then in addition PRG. The display Shows
--ok--.
Now you tan disconnect the controller from the mains. Your
settings are saved permanently under “Parameter set 1”.
Ta save different Parameter Sets see page89.
2.3
Load Parameters
If you only need one Parameter set, you permanently save your
changes under Parameter set 1. After every mains connection,
Parameter set 1 is loaded automatically. To load different
Parameter Sets, see page 89.

Basic settings
3.1
Operating mode
The controllers of the 8600 series offer different interfaces. From
these you tan select each one for control and programming.
Controller interfaces for control and programming:
Terminals
The terminals are exclusively used to control the
controller.
Keyp’ad
The five keys and the plain text display tan be
used mainly for programming. A control via the
keypad is also possible.
LECOM 1
LECOMl means the connection for LECOMNB
(connector X6) which tan be used for programming
via a PC or other master Systems. The Signals are
processed according to the FIS232 and FIS.485
Standards. You tan connect the controller to a
host using the X6 connector.
For further information about LECOMI
see page 140.
-
LECOM2
For more sophisticated applications, you tan
control and program the controller via a field bus
connecting module using LECOM2. Here, the field
bus Systems InterBus-S or PROFIBUS with the
DRIVECOM Profile are used. For further
information about LECOM2 see page 141.
You tan set the desired combination using code CO01 “operating

3.2.1 Example of how to select a configuration
The direction of rotation of the motor in a System is to be
determined by the sign of the analog setpoint
(O...+iOV for CW
rotating field, O...lOV for CCW rotating field).
A closed-loop Speed control is to be used, for which a DC tacho
serves as act. value. A setpoint 2 is not used.
The corresponding configuration tan be determined as follows:
The table “Closed-loop Speed control” contains two configurations
where the setpoint 1 is provided analog as bipolar setpoint. These
are the Parameters -1 l- and -13-. The desired closed-loop Speed
control using DC tachogenerator is possible with Parameter
-1 i-. The setpoint 2 via terminals 1 and 2 is active, but is not
required. Therefore its influence must be set to zero as protection
from setpoint couplings. Please observe the notes on page 68.

Features of setpoint 1
An analog entry of setpoint 1 is possible via input Xl/terminal 8,
otherwise it is entered via the keypad or the LECOM interfaces.
This depends on the selected operating mode (Cool). The
configuration determines whether the input is unipolar, bipolar, or
independently of the operating mode, a digital frequency input.
With terminal control you tan read setpoint 1 under code C046.
Under code Cl72 you tan select whether the setpoint is to be
displayed in per cent (related to fdma) or as absolute value.
With control via keypad or LECOM you tan enter under Cl 72 how

3.7.2 IO contra1
“Io control” is especially suited for machines with a large
breakaway torque. Compared to the V/f-characteristic control it
provides considerably larger torques up to the motor rated Point.
The advantages of IO control tan be used especially for Single
drives. lt is also possible for group drives, provided that the motors
are of the same type and have the same load, e.g. two identical
drives, which drive a common shaft from two sides.
V/f-rated frequency
To program the Io control, the Io setpoint and the correct V/f-rated
frequency must be set for the motor(s) (see page 70).
Io setpoint
You tan determine the Io setpoint using the cos<p , the rated motor
current and the following diagram.

Closed-loop speed control
For a number of applications, the accuracy which tan be obtained
with open-loop Speed control is often not sufficient. To avoid a
Speed reduction which occurs when an asynchronous motor is
loaded, you tan select a configuration with a Pl controller. The
appropriate configuration depends on the way of setpoint input and
the actual value input you want to use.

Frequency Pilot control
For applications where the act. value Signal is directly proportional
to the Speed of the drive (actual Speed) it is advantageous to pilotcontrol the output frequency with the setpoint or act. value. The
influence of the PI controller tan be limited such that only the
maximum machine Slip to be expected is controlled.
Setpoint Pilot control
A Pilot control of the output frequency with the setpoint offers the
advantage that the drive cannot accelerate unexpectedly if the act.
value Signal fails (tacho failure). The ramp generator for the
setpoint must be set correspondingly so that the drive is able to
follow setpoint changes.
(Tir-, Tit setting as for frequency control).
Actual value Pilot control
When the output frequency is pilot-controlled using the act. value,
the machine is supplied with the synchronous frequency which
corresponds to the actual Speed, without the influence of the Pl
controller (output Signal = 0). The Pl controller is only activated
effective if setpoint and act. value are not identical. When the Pl
controller increases or decreases the output frequency, a torque is
generated in the machine so that the drive accelerates in the
desired direction.
The advantage of act. value pilot control is that the setpoint slew
rate does not have to be limited (Tir, Tir = 0) and that the drive tan
run through a large Speed setting range with the set torque according to the set influence of the Pl controller.
A disadvantage is that the drive may accelerate unexpectedly in
the case of inadequate gain of the actual value.
If you want to use the act. value Pilot control, first adjust the act.
value gain with setpoint pilot control. After successful adjustment
you tan then Change to act. value Pilot control.

Adjustment of the act. value gain
If you use an incremental encoder for Speed control and you have
entered the encoder constant as described under 4.2. (see page
Fehler! Textmarke nicht definiert.) an adjustment of the act.
value gain is not necessary. For tacho act. value, a gain
adjustment is normally required.
4.4.1 Automatic adjustment
To adjust the act. value gain you tan activate an automatic
adjustment under C029. Proceed as follows:
Activate the closed-loop Speed control (COO5) with Pilot control
of the output frequency by the controller reference
(C238 = -l-).
Set the influence of the Pl controller to zero under C074.
Idle running. If this should not be possible, please note that the
Slip of the machine is added as gain error during the automatic
adjustment. If necessary, set manually.
If possible, enter 100% setpoint. If the setpoint is smaller than
10% an auto-adjustment is not possible.
Enable the controller and wait for the acceleration.
Activate the auto-adjustment via CO29 using SH + PRG.
If the auto-adjustment was successful, “--ok--” appears on the
display. If not, please check your settings. With the acceptance
of the auto-adjustment the act. value gain is set under C027.
Set under CO74 the influence of the PI controller such that the
Slip occuring during Operation tan be controlled.
To set the adjustment time and the gain of the Pl controller see
page Fehler! Textmarke nicht definiert..
4.4.2 Manual adjustment
If, for technical reasons, the above described automatic
adjustment in idle running is not possible or too inaccurate, you
tan measure the motor Speed by hand and calculate the required
act. value gain. Proceed as follows:

obtainable adjustment result is normally less precise.
Enable the controller and wait for the acceleration.

Additional functions
For special applications, you tan use a variety of additional
functions:
-
Input integral action component = 0
Using this function, the integral action component (I-component) of
the PI controller tan be reset to zero. You tan activate this
additional function via one of the freely assignable digital inputs.
Fur further information about programming of the freely assignable
inputs see page 81.
This function is e.g. useful for applications where a drive Comes to
standstill either after zero setpoint and remains in standstill without
the controller being inhibited. By resetting the
I-component, a motor drifting is avoided. If the drive is braked
mechanically with zero setpoint, a resetting of the 1-component
avoids the drive to jerk after releasing the brake.
Output act. value = setpoint
The digital function act. value = setpoint Shows that the controller
deviation (differente between setpoint and act. value) is within a
certain preset range. The thresholds are considered as a window
which you tan determine under C240. The value to be entered
refers to fdmax (CO1 1).

You tan assign the function to one of the freely assignable digital
Outputs. Fur further information about programming of the freely
assignable Outputs see page 90.
Output act. value = 0
The function act. value = 0 Shows that there is no act. value or the
motor does not run. The range, where the function is active, is
fixed in the form of a window of + 0.5% related to fdmax.
You tan assign the function to one of the freely assignable digital
Outputs and use it for example to reset the I-component of the Pl
controller. Fur further information about programming of the freely
assignable Outputs see page 90.
Act. vaiue display
The Speed act. value is displayed under code CO51. According to the
display of the setpoint 1 (CO46), you tan select a relative or an
absolute display in Hertz. In open-loop control (without Speed feedback) “0” is shown under CO51, srnce the act. value input is not used.
Monitor Signals
You tan assign the input and output data of the Pl controller to the
freely assignable monitor Outputs, if necessary. For closed-loop
Speed control with frequency Pilot control, the controller output is
an approximate value for the motor torque.

under C036. The brake voltage also determines the brake current
and therefore the brake torque. If the current limitation is activated
by the brake current, reduce the brake voltage.
To limit the time of the DC-injection brake, you tan program a
holding time under C107. After the holding time has elapsed, the

Chopper frequency
The controllers of the 8600 series offer the feature to adapt the
chopper frequency of the controller to the noise and smooth
running requirements of the motor. By increasing the chopper
frequency you tan generally reduce the motor noises which are
generated by the pulsating output voltage.
By reducing the chopper frequency the smooth running in the low
frequency range is often improved. Under code CO18 you tan
select a variable or fixed chopper frequency.
Variable chopper frequency
With a chopper frequency, from 4 to 16 kHz variable, the set
chopper frequency is maintained us long as the switching losses in
the controller allow for this. If an overload is recognized, the
chopper frequency is reduced automatically to the extent as it is
necessary to continue Operation. If the motor current is reduced
again, the chopper frequency is increased.
-
Fixed chopper frequency
When a fixed chopper frequency is set, the chopper frequency is
not reduced in case of overload. A fixed chopper frequency is
useful only when the reduction of the motor noise is important in
every operating state or if motor noise filters are used. By reducing
the maximum current internally, the overload capacity is restricted.

If you want to operate the frequency controller with 4 kHz (Cl43 =

automatic chopper frequency reduction, restricted to this range. For
this, enter the output frequency under C143, below which the
chopper frequency is to be reduced automatically to 2 kHz.
When selecting the chopper frequencies “12kHz fixed”
(CO1 8 = -7-) and “16 kHz fixed” (CO18 = -8-), you must set Cl43
“Threshold for automatic chopper frequency reduction to 2 kHz” to
0.0 Hz. Otherwise the controller would reduce its chopper
frequency to 2 kHz below the set threshold. This may darnage or
destroy connected filters.

9.2.1 Diameter detection
The actual winding diameter is detected by a Sensor and provided
to terminals 1 and 2 of the controller as an analog Signal 0 - 1OV.
This Sensor tan either be used in non-contact Operation (e.g.
ultrasonic, Optical Sensors) or in sampling Operation (e.g. sampling
Potentiometer).
The non-contact Sensor detects the distance between the Sensor
and the circumference of the winder and transmits the Signal to the
controller. The internal program tan detect the actual winding
radius also in this case.
104
lmze
--
The controller divides the Speed setpoint by the actual winding
diameter. The Speed setpoint tan either be provided by a JOG
value, an analog input terminal X8, or by the digital frequency input
X5. When changing the operating mode, also the operating unit or
one of the LECOM interfaces are available.
This procedure allows a Pilot synchronization of the circumferential
Speed of the bale to the line Speed. That means that the field
frequency is high for small diameters and low for large diameters.
9.2.2 Dancer-Position controller
The dancer has the following tasks:
l
l
l
-
Generation of the tensile stress of the material by means of a
weight or pneumatic cylinder.
Gompensation of eccentricities in the bale caused by the
rnobility of the dancer.
l-he actual Position is detected via a Sensor (Potentiometer or
non-contact System).
The dancer-Position controller is a closed-loop control of the line
Speed. lt compensates all deviations of the Pilot control channel
and the motor Slip which depend on the load.
9.3
Loop or dancer-Position control for line drives
An example of loop or dancer-Position control is the drive of two
conveyor belts which transport material. The material forms a loop
between the two conveyor belts or Passes a dancer cylinder.
The dancer or the loop is controlled in that way that the Position of
the slack is kept constant and thus the Speeds of the two conveyor
belts are synchronized
For this purpose, the corrected dancer Signal is multiplied by the
value of the digital frequency. The product of this multiplication is
added to the value of the digital frequency. For further information
see chapter 9.14.
9.4
Grinding or cutting-off wheel drives
If the surface Speed of the wheel has to remain constant in spite
of lwear, the motor Speed has to be adjusted reciprocally to the
wheel diameter. Therefore, the actual wheel diameter has to be
detected by a Sensor. The generated Sensor value is transmitted
to the controller which adjusts the drive to a constant Speed. For
this purpose, the dancer-Position control has to be switched off
internally.

Adjustment of analog inputs
Offset adjustment of the analog input terminals 7/8 (setpoint
input 1) and terminals 1/2 (setpoint input 2):
- Adjustment only with activated controller inhibit
(e.g. via low Signal at terminal 28).
With the final configuration CO05 = -2Ol- or -202-, an
unwanted Operation of the drive may occur during
adjustment and activated controller enable. That
means, the drive could accelerate to fmax while
adjusting the inputs when the setting controller enable
is activated, although only a very small setpoint was
provided.
For more information about the procedure see chapter 3.6
l
Gain adjustment of the analog input, terminals 3, 4 (actual
dancer-Position value):
- The gain of the input voltage is adapted via a switch
combination of the DIO switch Sl.
Sl is located at the left-hand side of the control board
8602MP (board with control terminals). For this, remove the
cover of the controller.

Diameter and radius detection
The diameter is detected by means of ultrasonic Sensors, which
emit a distance Signal or a real radius Signal. Consequently, there
are different procedures to adapt the internal Signal processing.
The encoder Signal is always provided via the terminals 1 and 2.
This Signal is converted with a resolution of 12 bits plut sign bit
(this corresponds to a Signal resolution of +/- 4096; resulting in a
resolution of 1 OV/4096 = 2.44mV).
The input is equipped with a filter which largely suppresses
interference on the ultrasonic Signal when the field frequency is
calculated.
9.7.1 Signal of the ultrasonic Sensor: distance Signal
For the adjustment of the radius detection when using an ultrasonic
Sensor, which supplies a distance Signal, the sensor-axis distance
must be entered under code C180. This value must be entered in
Volts.
Calculation of the value for code Cl 80:
For the calculation the bale tan have any diameter. (lt does not
make any differente whether the minimum or the maximum
diameter is assumed.)
The value for code Cl80 is calculated from the distance Signal in Volts
- detected by the ultrasonic Sensor - and the measures distance as
weil as the bale radius.

9.7,.2 Signal of the ultrasonic Sensor: radius Signal
For setting the diameter detection by means of an ultrasonic
Sensor which detects the diameter Signal, zero has to be
programmed via code Cl 80.
9.7.3 Further information about the radius detection
The signs of the value set under Cl80 and the input Signal must
never be the same to ensure that the addition results in the
required radius Signal.
The percentage of the radius is displayed via code CO49 if Cl72 =
-0-. In this case 100% =l OV.
For diameter detection a ramp function generator is connected.
The acceleration time is entered via code C220 and the
deceleration time is entered via code C221. In Order to minimize
angular acceleration in case of wire breakage, it is recommended
thalt high values for acceleration and deceleration times are
programmed. The acceleration and deceleration times are to be
set such that the diameter changes tan be immediately detected
even at vmax and minimum diameter.
API absolute-value generator is connected in series to the ramp
function generator (only if CO5 = 201 or 202). As a result, an
unsigned number is generated if the result of the addition of the
Cl 80 value plus the input value is negative.

9.7.4 Gain adjustment - radius Signal
When selecting the dancer-Position control with diameter
evaluation of the setpoint, the gain of the radius Signal must be set
such that an appropriate output frequency is generated when
having a fixed setpoint and a certain radius.
-
Coarse adjustment:
1. Before adjusting the radius Signal, the analog inputs must be
set.
2. Set CO25 = -l-.
3. Calculate correction factor C027:
- Determine minimum radius as a voltage value
Distance Signal [V]
rmin [VI = ren [mm] * Distance a [nun]
- Calculate CO27 (1.25 [V] is an internal calculation factor)
CO27 = 1v25[vl = 1.25[V]. Distance a [mm]
rti, [V] rmin[mm] . Distance Signal [V]
-
Example when using the values given in chapter 9.7.1:
rti, [V] = 150 mm .
8V
= 1.2v
1000 mm
CO27 = 1.25 = 1.042
1.2 v
4. Enter the calculated factor via C027.
In general, the gain of the radius Signal is set in such way that the
Speed setpoint is will not Change when having the minimum radius.
Precision adjustment:
1. Deactivate dancer-Position control Cl 92 = OHz
2. Install empty core (with minimum diameter) or enter minimum
radius as voltage [V] across terminals 112
3. Activate controller enable
4. Enter maximum setpoint of the line Speed
5. Select analog setpoint input 1/2 using CO25 = -l6. Change CO27 until the field frequency entered in CO46 is
displayed under CO50

9.7.6 Operation without diameter Sensor
If you do not connect an external Sensor to detect the radius, you
tan either use a fixed voltage connected to terminals 1,2 or a wire
brijdge with an internal setting of offset or C180. The gain
(C.O25/CO27) of the radius Signal should be adjusted in such way
th,at the required field frequency is reached under CO50.
This operating mode tan be switched with or with influence of the
diameter compensator (see 9.11.1). However, the best control
response is reached when using a radius Sensor.

Adjustment of the dancer-Position controller
9.8.1 Setpoint Provision
-
The act. value Signal of the dancer-Position controller is set via the
terminals 3 and 4.
The input Signal is displayed as percentage under code CO51 with
Cl72 = -O-. In this case IOV = 100%. The input Signal is resolved
with 12 bits (iOV/4096 = 2.44mV) plus sign.
For the input of the dancer-Position setpoint, the dancer must be
adjusted normally to the desired operating Position. The percentage
tan be read under CO51, this value must be changed into Volts
(1 OV=l 00%) and then entered under Cl 81.
Example:
CO51 = -48%
Cl 81 = -48% * 1 OV/i 00% = -4.8V
The differente between setpoint and act. value value of the dancer
is entered into the PID controller as input value. When changing the
direction of rotation _ calused by e-g. a reversing command via the
terminals 21 and 22 - the input Signal of the PID controller is also
inverted.
-
Caution!
DO not reverse the direction of transport (coupling in the dancerPosition control loop) by reversing the direction of rotation via the
digital inputs, terminals 21,22. For returning the material, inverl the
input Signal for the line Speed (main setpoint)

9.9.1 Overlay of Position controller
The function “overlay of position controller” is necessary for the
Start of the winding-up process with the dancer in an extreme
Position. The full effect of the dancer-Position controller could lead
to extreme operating conditions. Therefore the slow overlay of the
output Signal is necessary when starting the winding-up process.
The function “overlay of Position controller” tan be achieved via
freely assignable terminals, keypad, or the serial interface. The
“overlay of Position controller” is based on a ramp function
generator which controls the drive according to the acceleration
and deceleration time Cl 88 when activated. (The acceleration time
corresponds to the deceleration time).
The ramp function generator of the “overlay Position controller” is
reset after each controller inhibit. That means, when enabling the
controller again, the ramp function generator is accelerated
provided that the function “overlay Position controller” is activated.
For programming the freely assignable terminal, the terminal which
is to be assigned to the function “suppression of dancer-Position
controller” must be selected under code Cl 12. The function is set
under code Cl 13 and thus transmitted to the terminals selected
under Cl 12.

9.9.2 Conversion of modulation of dancer-Position controller to field
frequency
Code Cl 91 is a calibration factor which is used to convert the
modulation of the dancer-Position controller into a frequency. The
unit of this code is mHz/%. That means that the user assigns the
corresponding field frequency with 1% modulation of the dancerPosition controller.
Example:
With Cl 91 = 290 mHz/%, 100% modulation of the dancer-Position
controller corresponds to a field frequency of 29 Hz.

Limitation of the modulation of the dancer-Position controller
The frequency which is determined by the modulation of the
dancer-Position controller and the factor programmed under Cl 91,
tan be limited to permissible values under code C192. For this, a
field frequency is entered under code Cl92 which limits the
calculated value to the “armsture setting range” (that is the
frequency range from OHz to the V/f-rated frequency C015)
In the “field weakening range” (frequency range from the V/f-rated
frequency CO1 5 t0 fmax CO1 1) the Slip of the machine is increased
and t he field frequency is increased by the same factor squared.
Therefore, the increase of the limitation depends on the field
frequency.

9.10 Diameter compensator
The diameter compensator compensates errors that occur slowly
(e.g. unlinerarity of the ultrasonic Sensor).
If the dancer-Position controller output exceeds the threshold set
under Cl 94 (trigger diameter compensator), a ramp generator is
activated and counts from zero on. This counter Signal is added to
the diameter Signal and thus, the value falls below the threshold set
und,er Cl 94. As a result, the diameter Signal increases when
exceeding the positive threshold and thus the field frequency CO50
decreases. The diameter Signal is increased if the value falls below
the negative threshold - which has the same magnitude as the
positive threshold.
115
To activate the diameter compensator the threshold which is to be
set under C94 must be decreased so that the dancer-Position
controller tan be activated. With the setting of Cl 94 = 100 %
(factory setting) the diameter compensator is disconnected from
the dancer-Position controller.
-
9.10.1 Reset of the diameter compensator
The diameter compensator tan be reset (e.g. after finishing the
winding process) via a freely assignable digital input, the operating
unit, or the LECOM interfaces.
Select the freely assignable terminal which is to be assigned to the
function “diameter compensator reset” via code Cl 12. This function
is assigned to the freely assignable terminal under code Cl 13. If
the diameter compensator is enabled via the freely assignable
terminal, the thresholds will be compared first. When activating the
“diameter compensator reset”, the counter value is set to Zero.
After each mains connection, the diameter compensator is set to
Zero.
-
Caution!
If the controller is enabled when the diameter compensator is reset,
then the counter value is set to zero immediately. Thus, with a high
diameter compensator percentage - when activating the “diameter
compensator reset” - the diameter value which is part of the
division changes abruptly and as a result the field frequency is also
changed. This may lead to high accelerations and the current
limiting function Imax may be activated.
The integration time tan be set under code Cl 95 (unit [s]), and the
decrement time tan be determined under Cl96 (unit [s]).
If the output of the dancer-Position controller falls below the
threshold set under Cl 94 after the diameter compensator has
already been activated, the correction value of the diameter
compensator will not be changed as long as
l
l
l
the diameter compensator is reset via a freely assignable
terminal or
the supply voltage of the frequency controller is switched off
(e.g. the controller is not connected to the mains) or
the diameter compensator has to be activated again because
the output of the dancer-Position controller exceeds the
threshold set under Cl 94.
The function Cl 94 is not reset by controller inhibit.
The threshold set under Cl 94 refers to 100% of the modulation of
the dancer-Position controller.

-.
The diameter compensator tan also be used for indirect diameter
detection where there is no diameter detection System. The
modulation of the dancer-Position controller enables a slow control
of the diameter compensator output, until the dancer-Position
controller returns to a modulation window (Cl 94) to be set. The
acceleration and deceleration times C 195/C196 must be set in
seconds so that an instability in the control caused by the dancer
modulation is avoided. The acceleration and deceleration times
should be set so that a diameter increase tan still be compensated.
9.11
Input of correction value
(only for asynchronous machines)
The correction value for the field frequency tan be set during
acc’eleration (see Signal flow Chart page 120). This value tan only
be entered as a bit value (+ 16383 to - 16383) via the serial
interface under code Cl 93 . lt tan be saved via CO03. The
resolution and the increment of the correction value is 0.03 Hz - as
the entered value 16383 equals 480 Hz.
Recommendation:
The entered correction value should not exceed the rated Slip
frequency.
Caution!
The entered value is immediately added to the calculated values
without being processed by the ramp function generator. That
means that high correction values may lead to high torques and the
current limiting function lmax tan be activated (see Signal flow Chart

9.12 Application: Tandem winder
9.13.1 Digital frequency output
The digital frequency output is required e.g. for a master Slave
coupling (two motors are connected by friction to one winder shaft).
For master-Slave couplings it is important that, in case of Speed
reduction of the master, e.g. due to the current limiting function
Imax,, the Slave Passes the same field frequency to the motor as the
master.
A frequency Signal which is proportional to the field frequency tan
be supplied to terminal X9. To activate this function the value 200
must be set under CO08. The corresponding setting of pulse/Hz
tan be calibrated under CO30 (see chapter 5.6).
9.12.2 Information about the Slave drive
The Slave drive tan either be equipped with the series Software or
the variant Software. Only the master drive must be equipped with
the variant Software VOO9 which is valid for the dancer-Position

Caution!
The acceleration and deceleration times (CO1 2EO13) of the Slave
must be 0 sec in the tandem winder application. Otherwise, the
shaft will undergo torsion when accelerating or decelerating the
drive.

Application: Loop control with Speed adaption
Among others, a loop control is required for the transport of
material by means of two conveyor belts. The slack which occurs
between the two conveyor belts is kept constant by the loop
control.
To ac:tivate the loop control the code Cl 89 must be set to -0- but
only with activated controller inhibit.
Usually the field frequency Pilot control is not used for the loop
control. Therefore e.g. 2V has to be entered under Cl80 as
diameter setpoint. Afterwards the Pilot control has to be set such
that the setpoint of the field frequency CO64 corresponds to the act.
value of the field frequency CO50.
The FYD controller must be set in the same way as the dancerPosition controller.
Caution!
-
The direction of rotation may be reversed if the loop controller is set
too high, the ouput is e.g. negative and the master frequency input
is positive.

10.1 Features
The torque control is used to supply a torque which is proportional
to the setpoint, depending on a torque reference at a connected AC
asynchronous machine. For this, the torque setpoint is entered via
an analog Signal input which is permanently compared with the
torque supplied to the motor shaft.
If the torque setpoint exceeds the act. value torque, the field
frequency and thus the output voltage is reduced until setpoint and
act. value are identical. If the act. value torque is reduced when the
load is removed from the drive, the field frequency is increased
again.
A motor without load and with a torque setpoint higher than OV will
accelerate to the field frequency setpoint, i.e. the drive operates as
torque Source.
-
The following torque characteristic Shows the behaviour of the
torque control.

The torque control tan only be used in the motor mode and in
the armature setting range (range of constant motor excitation
from 0 to V/f-rated frequency).
In this configuration, only one motor tan be connected.
The torque control has an Optimum effect only with activated
magnetization current control (CO06 = -1-) .

Setting of the torque controller
Activation of the torque control
The torque control is activated via CO05 = -2O- (analog setpoint) or
CO05 = -21- (digital setpoint).

Adjustment of analog inputs
Offset and gain of the analog inputs must be set according to
chapter 3.6.
In this configuration, terminals 3 and 4 act as input of the torque
setpoint. Depending on the maximum input voltage, a suitable
switch combination must be set on the switch group Sl. The switch
group Sl is set such that a maximum input voltage of 120V is
expected at terminals 3 and 4.
This switch group is located at the 1.h.s. of the 8602MP (board with
control terminals). For setting, remove the cover of the frequency
controller.

Adjustment of the Imax limit
The torque controller has the same functions as the Imax limit
controller. The Imax current entered under code CO22 corresponds
to the maximum torque which the motor is able to perform.
Example:
If Imax is set to the rated current of the connected motor, the motor
tan only be loaded with the rated torque.
If a voltage of 1 OV is applied across terminals 3 and 4, the torque
setpoint is the same as the torque which the motor is able to
provide with the set Imax current.

Adjustment of the torque controller
The torque controller must be set when the drive is under load,
provided that there is a rising torque characteristic of the load over
the Speed.
Set the field frequency setpoint for the torque setting.
When entering the torque setpoint, a torque reserve must be
provided which depends on the acceleration time and the inertia.
For this, a torque balance must be established.
After the drive has accelerated to the frequency setpoint the Speed
and thus the output torque tan be reduced until the desired
operating Point is reached. This is done by reducing the torque
setpoint at terminals 3 and 4.
126
The quality of the control behaviour is set via the Vp-gain factor
CO77 and the adjustment time Tn C078.
Therefore the field frequency is reduced with a reduction of the
torque setpoint, until the ratio between Speed and torque is stable.
If the ,torque setpoint is increased, the field frequency increases.
Here, the field frequency input via terminal 8 or via the digital
frequency input or via code CO46 is used to limit the maximum field
frequency.

12 Serial interfaces
-
The frequency controllers tan communicate with superimposed
hosts (PLC and PC) and the Lenze operating units 323 and 324 via
the serial interfaces LECOMl and LECOM2.
12.1 LECOMI interface X6
The LECOMl interface (X6 connector) tan be used to connect
devices to the RS232C Standard (LECOM-A) or to the RS485
Standard (LECOM-B). The interface is suitable for Parameter
setting, monitoring, diagnosis, and simple controls.
Using the very common RS232C interface, simple point-to-pointconnections with a cable length of a maximum of 15m are possible.
Almost every PC or other hosts have this interface.
Using the RS485 interface, several controllers tan be connected to
a superimposed host (multi-point connection). If you use the
2101 IP interface, cable lengths up to 1200m are possible.
The LECOM-NB protocol is based on the ISO Standard 1745 and
supports up to 90 drives. lt recognizes faults and therefore avoids
the transmission of incorrect data.

12.2 LECOM2 interface (Option)
For more sophisticated applications, you tan use a field bus
connecting interface. In the programming section, this interface is
called LECOM2. For the bus System Interbus-S the connecting
interfxe 2110 with the DRIVECOM Profile is available. For the bus
System PROFIBUS the connecting module 2130 is also available
with DRIVECOM Profile. The modules 2110 and 2130 are available
are Options and tan be integrated into the controller (See also page
52).
12.3 LECOM Codes
Some Codes have a special meaning for the serial communication.
The codes C043, C068, C069, Cl61 to Cl68 cannot be read on
the dispaly of the device.
12.3.1 Controller address

technical description LECOM-A/B, which we will be pleased to send
you on request.
12.3.8 Enable automation interface (LECOM2)
If you want to integrate the controller into complex automation
Systems, you tan connect an interface, e.g. Interbus-S or Profibus
or an automation module. Install the module and activate it under

Under Codes C380 to C382 you tan enter very precise setpoint and
act. value with a resolution of 14 bit plus sign.
Setpoint 1:
Setpoint scaled to the maximum frequency. The value of 214
corresponds to 100% of the maximum field frequency. The
inforrnation is identical with that under C046, with the differente
that you tan read the controller value directly thus excluding
conversion errors.
Total setpoint:
Total of main setpoint 1 and setpoint 2, each behind the ramp
generator, scaled to the maximum field frequency. The total
setpoint corresponds to the setpoint of the PI controller in closedloop control. The value of 214 corresponds to 100% of the
maximum field frequency.
-
Act. value for the Pl controller, scaled to the maximum field
frequency. The value of 214 corresponds to 100% of the maximum
field frequency. The information is identical with that under CO51,
with the differente that you tan read the controller value directly
thus excluding conversion errors.

Fault indication
When a fault occurs, the Operation of the frequency controller is
immediately interrupted and the Signal “ready” is removed. The
fault is displayed automatically under C067. The fault indication is
flashing as long as the fault has not been reset.
Fault reset:
Press SH + PRG
or
activate the input TRIP reset.
Reset fault indications are stored. They tan be displayed again by
selected code CO67 and pressing the DOWN-key in the Parameter
level. A maximum of eight faults tan be displayed: the most recent
fault is displayed first; then one preceeding this and so on.
Operation via LECOM interfaces
With Operation via LECOM interfaces, a fault is also displayed
under C067, but as number (see table). Reset fault indications are
stored under Cl 61 to Cl 68.
You tan reset the fault by selecting Parameter -0- under code
co43.
