Linear Scales & Counters
Accurate, yet Affordable,
DRO System from Mitutoyo
Mitutoyo's DRO (Digital Readout) system integrates the scale units with the dedicated digital counters, to offer
accurate detection and display of axial displacements of machine tools and measuring equipment. The DRO system
can be configured to best meet your specific application, such as turning, milling, or grinding. Choose a suitable
combination of scale unit and counter. Scale units have diverse measuring length ranges and counters feature remote
zero setting, switchable resolution, and multipurpose one-touch macro keys. The DRO system has superior ease-ofuse and is reliable, both of which dramatically improve machining accuracy and efficiency.
Mitutoyo strongly recommends implementation of the DRO system whatever possible.

Features
• Digital counter value display allows quick and correct readout
of displacement. Working efficiency thus greatly improved.
• Zero-setting or presetting possible at any position. Versatile
functions eliminate calculations or complicated key
operations for positioning.
• Various external output features allow output of current
display values or various data to external devices such as PCs
or sequencers. Easy data processing can be performed.
• Two types of display units (counters) available: highperformance type and limit signal type.
• Both linear scale and display units (counters) conform to CE
marking standards. They also comply with the hazardous
substances restriction in the RoHS directive (2006).

Mitutoyo Kiyohara Plant, which is a factory exclusively for the
production of Linear Scales and other precision scales, has a
complete system for producing master scales to be used in finished
products, such as CMM, vision measuring system, profile projectors,
and measuring microscopes. To improve the accuracy of scales and
quality control technologies, the integral laboratory of Kiyohara
Plant was constructed eleven meters underground. It provides
an optimum environment (cleanliness factor: 100) for the ultraprecision manufacture and evaluation of scales. Its unique design
and construction isolate the laboratory from external vibrations and
ensure minimal variations in temperature and humidity.

Scale Unit
Features of Scale Unit
Features in construction
Detecting principle (AT100 series)
Main scale
Joint Structure of Detector
The ball joint structure is employed at the joint of the detector head
and the slider (sensor unit) inside the scale. This structure prevents
the slider movement from deviating from the normal moving
Sensor
directions when the detector head
Joint bar
shifts to right and left, thus providing
a normal scale reading and increasing
Spring
flexibility in the scale installation.
In addition, this structure is highly
rigid and therefore has an excellent
durability.
Index scale
Phototransister
Phase A
20µm
Water-proof Connector
A waterproof/splash-proof connector is used to enable separation of
the signal cable. Thus, an installation and maintenance of the Linear
Scale can be easily performed. (The signal cable in AT115 cannot be
separated.)
Phase B
Phase difference of 90˚
20±10µm
Scale reference
point signal
Conduit armored type signal cable
The signal cable is protected by the conduit system. Its exterior is
made of stainless steel, which is free from rust and corrosion and
withstands sustained use for many hours.
The detector of each scale unit consists of a light source (LED) and
a photoelectric device (photo transistor) which face each other
with the main scale and index scale between them. When the main
scale moves, relative to the index scale, the quantity of light that is
transmitted through the gratings on the index scale varies with the
same period as the grating pitch. This variation of light intensity is
converted into electrical signals and output as two-phase (A and
B) waves with a phase difference of 90°. The display unit divides
these signals to determine the direction of the scale movement, and
digitally displays the displacement of the scale.
Unique rubber-lip openings
The rubber-lip openings are shaped like the
bottom of a ship that plows the water.
Excellent splash- and dust-proof rubber lip structure
The rubber lips are made of a strong, special urethane, and wires
are inserted in these lips to improve the splash-proofing and dustproofing of the scale (AT102 only).
Second exciting coil
Detecting principle (AT715)
Mitutoyo has implemented an absolute encoder by combining
incremental encoders with different scale intervals. Two incremental
encoders with scale intervals of λ1 (first scale) and λ2 (second scale)
are incorporated as shown in Fig.4. The relationship between slider
displacement and induced voltages in the individual encoders show
different periods, λ1 and λ2. Due to this difference the induced
voltages do not coincide throughout the entire travel length of the
slider.
As shown in the figure left, the voltages V2a and V2b of the second
scale are different at positions Xa and Xb where the first scale
voltage V1a is the same. In other words, when the first scale voltage
is V1a, the second scale voltage is V2a only at one position, Xa, over
the entire scale length. Therefore, a unique combination of voltages
enables the absolute position of the slider to be determined.

Resolution setting
For each axis, the measured value can be obtained in
either absolute (ABS) or incremental (INC) coordinate
system. This function is useful, for example, if the
following operation is performed. Set the datum
point for a workpiece in the absolute mode. Then,
after performing zero setting, presetting, etc., in the
incremental mode, return to the absolute mode. In this
way the absolute distance from the datum point can be
easily displayed.

SPECIAL FUNCTIONS
Linearity error compensation

inaccurate table adjustment, etc., are linearly
compensated to reduce the positioning error.
e
Memory backup
The backup battery retains the most recent display value
even when the counter is off.

Smoothing
Smoothing makes the display value easier to read when
a minimum reading fluctuates due to machine vibration.
16
Expansion/contraction
coefficient setting
In the casting production, first a mold is fabricated
and then molten material is poured into the mold.
The material cools and shrinks while solidifying before
becoming a product. The mold must therefore be
fabricated larger by the amount of shrink. By using the
correction function of the counter, machining can be
performed with the finished product (molded product)
dimensions shown on the drawing. Bothersome work
can thus be reduced.
Display Unit
FOR MILLING MACHINES
Zero approach machining
[INC mode]
Zero approach machining can be repeated at a preset
interval without error. Since the counter keeps the total
displacement in the absolute coordinate system, the
error is automatically compensated for at each tool
position.
8
10
Pitch machining
Bores holes between two arbitrary points on the X-Y
plane at equal spaces. By inputting the number of holes
and positions of the start and end points, holes can
be bored easily at equal spacing. Errors due to table
positioning by the machine are automatically corrected
to the next target value.
Start point (x, y)
8
Scale reference point setting
The linear scale has scale reference points at 50mm
intervals. When one of the points is detected, the linear
scale issues a signal to hold/restart counting. If the
distance from a scale reference point to the machine
origin is registered as the offset value, it will be retained
even when the power is off (hold function). When the
power is turned on, the machine origin or machining
datum can be easily recalled (set function).

FOR LATHES
Diameter display
The doubled scale displacement can be displayed. This
convenient feature can be used to display the diameter
of a workpiece that results in a lathe cutting operation.
Addition of 2-scale data
The sum of the displayed values of two axes can be
displayed. If a machine has two feed components, fine
feed and coarse feed, each with its own scale, this
function can be used to sum the two feed values.
Cutting tool selection
Multiple absolute and incremental coordinates can be
set for an axis. If individual cutting tools installed on a
lathe are assigned dedicated coordinates, the tools can
be used whenever necessary by simply selecting the
tool, without resetting the machining datum point each
time.
Up to 5 tools can be registered on the KM/KC Counter.
Up to 10 tools can be registered on the KLL Counter.

Do not use the limit signal output through the relay of the KLD
Counter to directly control other devices such as motors. Always
route the relay output through another relay at the external device
side, as shown in the diagram above. Although the relay contact
circuit of the counter has varistors (threshold voltage: 300V), provide
a surge absorber on the external device to be connected, which may
generate surge current. For example, a varistor is recommended for
an AC circuit, and an appropriate diode is recommended for a DC
circuit.

Caution in mounting and handling Linear Scales
Selecting the scale unit mounting position
and mounting method
Checking parallelism
and adjustment of scale unit
Take note of the following four points when determining the scale
unit mounting position and orientation.
In order to get the most of the performance of the scale unit, the
scale unit must be mounted parallel to the machine guide (machining
axis). Take note that incorrect mounting may cause the scale unit to
bend or twist.
Ease of mounting
Mount the scale unit making sure that the unit including the detector
head and the cables does not interfere with any part of the machine.
To facilitate mounting, mount the scale unit and the brackets on
machined surfaces wherever possible.
Checking parallelism
Use a dial indicator as shown in the figure below. To adjust the
parallelism between the scale unit and the machine guide, check the
parallelism while manually moving the machine's movable part such
as the slide table, or measure the parallelism with reference to the
guide rail of the machine or equivalent reference surface.
Protection from machining fluids and swarf
(mounting orientation)
• Parallelism tolerance: Refer to each figure on dimensions.
• Checking direction: Back/forward direction on mounting
surface and directions
along mounting surface
Stroke
(up and down).
Dial indicator
• Checking position:

Up/down
blocks.
The scale unit is constructed in such a way that machining fluids
and swarf cannot easily enter into the interior of the unit. However,
since the openings are protected from entry of foreign material with
rubber lips only, avoid directly exposing the scale unit to machining
fluids and swarf. Select the mounting orientation of the scale unit
after carefully considering the direction in which machining fluids
and swarf are sprayed and scattered.
Accuracy consideration
The total system accuracy of the machine on which the scale unit is
mounted is not only determined by the scale unit accuracy but by
the machine accuracy as well. Particularly for machines with side
tables, geometrical errors may occur, depending on the straightness
of moving parts; Thus, the scale unit must be mounted in a way that
these errors are minimized. If the slide table moves not linearly but
curvilinearly, errors occur in proportion to the distance "L" between
the scale unit and the machining point (cutter position). Thus, mount
the scale unit in a position that minimizes "L".

Other considerations
Layouting signal cable
• If the detector head moves, the signal cables also move with the
slide table. Thus, take note of this when laying out the signal
cables. It is therefore recommended to mount the scale unit on the
moving part of the machine.
• Mount the scale unit in place where it is not directly subjected to
the airflow. When removing swarf using an air gun, be careful of
flying swarf.
• The scale unit must be mounted in a place where maintenance can
be easily performed in case unit trouble occurs.
Take note of the following points when layouting signal cables.
When the cable is fixed
The radius of curvature of the signal cable must be larger than
50mm.

Technical Information
When the cable is movable
Resonance point of Linear Scale
When the detector head is movable, it carries the signal cable
with it during operation. Take care, in such a case, that the radius
of curvature of the signal cable is not smaller than 100mm and
excessive force is not applied to the cable. It is a good idea to protect
the cable with a flexible support cover.
Each object has a natural frequency, depending on its shape, length,
and the type of material. The Linear Scale frame is not an exception.
It has its natural frequency and thereby resonates at a certain
frequency. In general, this will not cause a problem, since a machine
tool and the Linear Scale frame have different natural frequencies
under normal machining conditions. However, when the natural
frequency of the machine tool body and the Linear Scale coincide
due to a special processing condition, the following countermeasures can be taken:
[What to do when the machine and the Linear Scale have
the same natural frequency]
1. Increase rigidity of the mounting bracket for the scale.
2. Add a mid-support to the middle of the scale to shift its resonance
point.
3. Mount the Linear Scale at a place where the frequency of the
machine tool cannot be easily transmitted.
4. Limit the machine process conditions to be within a specific range
in which the natural frequencies of the machine tool and the scale
do not coincide.

head
Radius: 100mm or larger
Note: Take care that the signal cables does not interfere or are not rubbed with any part of the machine.
Other considerations
The signal cable is durable enough to withstand repeated bending
up to approximately 2 million times (when the bending radius is
100mm). When repeated bending exceeding 2 million times is
expected, the signal cable should be considered as a consumable
part. Have an extension cable ready in such a case so that the slider
unit can be replaced to facilitate maintenance.
Maintenance of Dust-proof rubber lips
In order to maintain and extend the life of the dust-proof rubber lips,
it is recommended that a small amount of silicon lubricant be applied
to the joint of the rubber and the detector head once a year.
Improving the dust- and splash-proofing
On the assembly type Linear Scale AT102 the dust-proofing and
splash-proofing can be improved by supplying dry and clean air into
the spar. Pipe to either of the screw holes (M5) located on the both
ends of the main scale for the air supply.

Traceability System
Mitutoyo has a traceability system made possible through
an in-house calibration organization certified by the ISO/IEC
17025 international standard, with length standards directly
related to the national standards (stabilized He-Ne laser) at the
highest level. The stabilized He-Ne laser assures a performance
equivalent to that of this national standard.
Further, the national standard is mutually recognized
by CIPM, and the certified calibration organization is
mutually recognized by ILAC, so that the establishment and
maintenance of traceability for Mitutoyo products is achieved
both in Japan and overseas.
