Functions
– Installation guide (DRO203, DRO300)
– Probing functions for presets (DRO300)
– Tool compensations (DRO203, DRO300)
Installation guide
At rst switch-on, an installation guide will
guide you step by step through the congu-
ration of the unit. During this procedure, you
can select the connected encoder directly
from a list and thereby adopt all of the encoder
parameters. It only takes a few moments to
congure the basic functions of the digital
readout.
You can then separately congure further
settings such as scaling factor, error
compensation, etc.
Easy setup with probing functions
A very useful accessory for datum setting is
the HEIDENHAIN KT edge nder: simply
move the edge nder toward a side of the
workpiece until the stylus deects. The
digital readout stores the exact position on
its own and automatically takes into account
the direction of approach and the radius of
the stylus or the tool. For this purpose, the
digital readout provides the following probing
functions:
• Workpiece edge as reference line
• Workpiece centerline as reference line
• Circle center as datum
Tool compensation for milling machines
The ACU-RITE digital readouts save tool data
in a tool table (i.e., diameter and length of the
tool used). The data can come from preset
tools or be measured on the machine.
When positioning in distance-to-go mode, the
readouts take the tool radius (R+ or R–) in
the machining plane into account and con-
sider the tool length (L) in the spindle axis.
Determining and storing tool
compensation values on lathes
You can store the data for the tools you insert
in the turret or quick-change holder in the
tool table:
• Enter the tool position directly when
turning the rst diameter, or
• “freeze” the current axis position value,
retract the tool, measure the turned
diameter and then enter that value.
Changing the datum
If you change the workpiece or a datum, then
you can set a new preset. The tool data are
then automatically referenced to the new
datum and do not need to be changed.
Compensation of tool radius and length
Convenient datum setting with an edge nder

– Distance-to-go display (DRO100, DRO203, DRO300)
– Dynamic zoom (DRO203, DRO300)
Distance-to-go display
for turning and milling
The distance-to-go display feature simplies
your work considerably: you enter the next
nominal position, and the display shows you
the distance remaining to the target position.
This means that you simply move to the
display value zero.
When you use the distance-to-go feature for
milling, the digital readout can compensate
for the milling radius. In this way you can
directly use the drawing dimensions without
having to do any conversions. You no longer
have to remember any complicated values.
Dynamic zoom
The dynamic zoom feature offers a signicant
improvement in position value readability.
Once activated, the display value for the axis
currently being moved is maximally enlarged.
This occurs in four steps depending on the
number of digits in the respective numerical
value. For small numbers (i.e., numbers close
to zero), the character height can be increased
from 17mm (standard height) to 25 mm. The
operator immediately sees which axis is
currently moving and can also easily read the
numerical value from a greater distance.
When the axis stops moving, the display
returns to its standard size after a second
has elapsed.
The distance-to-go display is enhanced by
a“near zero” message: as you traverse to
zero, a square cursor moves into a target
fork.The “near zero” message is
congurable for each axis.

8
Functions
– Hole patterns (DRO203, DRO300)
– Programming of machining steps (DRO300)
Automatic calculation of bolt hole
patterns for milling and drilling
In milling machine mode, you can machine
circular hole patterns (full circle or circle
segments) and linear hole patterns without
much calculation.
You simply enter the geometric dimensions
and the number of holes from the drawing.
The display calculates the coordinates of the
individual holes in the working plane.You
only need to traverse “to zero” and drill.The
display then shows the next position.The
graphic display is a particularly useful
feature: it lets you verify your input for the
programmed bolt-hole pattern before
machining.
Programming machining steps
The programming functions of the DRO300
allow you to save repetitive machining steps.
For example, you can save all of the
machining steps required for a small batch in
the form of a program. In the RUN mode of
operation, the distance-to-go display will
guide you step-by-step to the programmed
positions.
You create programs by typing in the
positions step by step.The xed cycles such
as Bolt Hole Circle, Linear Hole Pattern,
Incline Mill Form or Circular Arc keep your
programs short and save you programming
time. In the course of your work, the readout
presents each nominal position in the proper
sequence. You need only move from one
position to the next.

– Assistance for working with lathes (DRO203, DRO300, DRO303)
Radius/diameter display
In lathe mode, you can see the positions
ofthe transverse axis in either radius or
diameter values.You can switch at a
keystroke.
Sum display of longitudinal axes
In lathe mode, the positions of the saddle
and the top slide are displayed either
separately or as the sum of both values.
• If you select separate displays, the
position values are referenced to the
datum for each individual axis. If only the
saddle is moved, the displayed value for
the top-slide axis remains unchanged
• If sum display is selected, the counter
adds both values while taking the
algebraic sign into account. You can
thereby read the absolute position of the
tool in relation to the workpiece datum
without having to perform calculations.
•Vectoring (DRO203, DRO300)
The vectoring function breaks down a
movement into its longitudinal and
crossfeed axis components. If you are
turning threads, for example, vectoring lets
you see the diameter of the thread in the
X axis, even though you are moving the
compound axis handwheel
Taper turning made easy
(DRO203, DRO303)
If taper dimensions do not include the angle,
the integrated taper calculator will help you
with the calculation. Simply enter the taper
ratio or the two diameters and the length.
The correct angle for the top slide will be
displayed immediately.
Constant surface speed (DRO300)
Particularly in taper turning or parting, the
surface speed usually changes along with
the diameter. But a constant surface speed
is better for optimum machining results and
long tool life. In conjunction with the IOB 610
output module, the DRO 300 digital readout
therefore makes it possible to control a
constant surface speed contingent on the
current workpiece diameter.

Analog output
Constant surface cutting speed CSS
(only in turning applications)
CSS provides spindle speed control as the
diameter of the workpiece changes. A speed
command signal is sent to the inverter of the
spindle motor via the analog interface (DAC 0
V to 10 V) of the IOB 610. The maximum and
minimum permissible spindle speeds can be
specied. In addition, a maximum of three
operating gears can be taken into account.
The DRO300 recognizes the current gear
stage by means of the switching inputs of
the IOB 610. CSS control can also be started
remotely (via an input to the CSS board) with
an external switch.
Controlling the spindle speed
(only in milling applications)
With the analog outputs, the speed of the
spindle on milling machines can be controlled
in an open controlled loop. A spindle speed
can be assigned to each tool dened in the
tool table. The speed can be manually
adapted during machining.
Switching outputs
The IOB 610 features ten oating relay
outputs.
Standby
The standby output is at LOW level if the
DRO300 cannot operate the IOB (e.g., not
switched on, cable disconnected, etc.).
Switching functions
(for milling applications)
One or more switching ranges or switching
points can be dened for an axis.The
switch-off ranges are located symmetrically
around the display value 0. If switching
points are used, the relay activates when
the position display reaches a specic value.
The direction function switches when the
algebraic sign is changed.
You can set whether:
• the switching function should apply to the
actual value or distance-to-go mode,
• the relay will open or close when the
condition is met
• or the relay remains activated as long as
the switching condition is met (continuous
mode) or for a specied duration (pulsed
mode).
