3 Assembly and commissioning
The digital position display DPA 2000S is preassembled.
INFORMATION
If you want to use the digital position display you need at least one measuring gauge. Measuring
gauges are not part of the delivery volume of the digital position display.
The position display DPA 2000S offers you the option to connect absolutely measuring as well
as incrementally measuring position sensors.
Only use original OPTIMUM path-measuring systems, since the position display is only adjusted to such path-measuring system and this way will guarantee a safe functioning.
3.1 Delivery volume
Upon delivery immediately check if the device had been damaged during transport. Compare
the delivery volume with the data on the delivery note.
3.2 Storage
CAUTION!
In case of improper storage it is possible that important components are being damaged
and destroyed.
Store the packed or a lready unpacked device only at dry environmental conditions at a
temperature from 0 °C to 40 °C.
If you need to store the device or any accessory parts for more than three months and under
other environmental conditions than those prescribed by this manual, contact the company
Optimum Maschinen Germany GmbH.
3.3 Adding the device
3.3.1 Requirements for the installation site
CAUTION!
When choosing the installation site , please take into account the length of t he connect ion
lines for the measuring gauges.
The installation site needs to be dry and vibration-free and comply with the ergonomic requirements of a working place. Observe the safety instructions for working nearby machine tools.
The working area for the operation, maintenance and repair works must not be hindered by
adding the position display.
3.3.2 Installing the device
The device needs to be positioned freely at an appropriate place or be mounted to a horizontal
subsurface or to a wall using the attached fixing material.
3.3.3 Assembling the measuring gauges
Measuring gauges are linear measuring systems which collect the position of mobile machine
parts via a sensor and forward them coded to the position display.

GB
CAUTION!
Only use path-measuring systems recommended by OPTIMUM. When assembling the
path-measuring systems imperatively follow the instructions of the manufacturer.
Before mounting it on the machine, check the operability of the measuring gauges. To do so,
use the digital position display DPA 2000S or a similar device.
Install the measuring gauge in a way that it will not be damaged by cutting tools or coolants.
If required, mount a cover.
If possible, mount the enclosed measuring gauges with the sealing lips showing downward.
If possible, place the reading head stationary in order to avoid damages of the connection
lines by its movements.
CAUTION!
The path-measuring system and its add-on pieces can cover important components on the machine tool (e.g. lubricating nipples).
Before mounting the path-measuring systems, please note such limitations in functions and
make arrangements accordingly.
3.3.4 Assembly of the reading head
Mount a fixture for the reading head.
Fix the reading head to the fixture.
Remove possibly existing assembly aids from the reading head.
Check the orientation of the reading head using a dial gauge
(refer to the tolerances for the assembly given by the manufacturer).
Check if all components are moving freely.
3.4 Linking the position display to a frequency converter
The position display DPA 2000S is equipped with the function „cutting constant“ which allows to
influence the spindle speed of a lathe in a way that the same cutting speed will result at the working point of the tool independent from the workpiece radius.
To do so, the control of the DPA 2000S will directly influence the frequency converter (FC).
We mainly use frequency converters of the manufacturer LENZE for OPTIMUM lathes.
Therefore, we will explain the linking of the DPA 2000S to this frequecy converter in detail below.
3.4.1 System requirements:
To operate only using the function „cutting constant“ a frequency converter (FC) having an
analog input 0 V - 10 V DC is required.
For an operation using the function „cutting constant“ for remaining options of the manual speed
regulation, a frequency converter with two analog inputs is required:
0 V - 10 V DC for speed control via DPA 2000S (cutting constant control)
0 V - 05 V DC for speed control via the potentiometer
The following items are required in addition:
ON/OFF switch to switch over between the manual speed setting and the cutting constant
control

GB
ON/OFF switch to switch over between the working ranges 1 and 2 for cutting consta nt opera-
tion (refer to commissioning)
Potentiometer for the manual speed setting (e.g. 1kΩ for frequency converters made by the
manufacturer LENZE)
Application module made by LENZE (type E 82 ZAFAC 001)
Perforated disk for the speed recording (with 8 holes for small and 16 holes for large lathe
chuck seats)
Fork light barrier for speed recording
Please refer to the current OPTIMUM main catalog for optional accessories.
3.4.2 Electrical connection:
The connection to the DPA 2000S is performed via the cable included in the delivery volume
using SubD plugs - 15 pins (refer to page 11 paragraph 2.5)
1. Connect the grey cable (1) from the SubD plug to the black cable of the fork light barrier.
2. Connect the brown cable (2) to the brown cable of the fork light barrier.
3. Connect the blue cable (6) to the blue cable of the fork light barrier.
4. Bridge over the green (3) and the blue cable (6).
5. Connect the red cable (5) to the frequency converter at the input for the control voltage
(0 V - 10 V)
6. Connect the yellow cable (7) via the switch (NO switch) to the blue cable (6).
7. Connect the white cable (9) for analog grounding GND to GND at the frequency converter
(for LENZE FU terminal 7).
Wiring diagram to connect the DPA 2000S on the following page
You need to set the maximum admissible speed of the lathe using the FC.
Danger!
Do not exceed the maximum speed of the clamping devices. You can only make sure the
limitation of the maximum speed by using the FC.
Set the frequency converter in a way that the maximum admissible speed of the clamping
device will not be exceeded for both working ranges of the DPA 2000S.
In order to achieve the maximum possible speeds for the „cutting constant control“ which is
resulting of the combination of your lathe with the position display it might be necessary to use
clamping devices of a higher maximum speed.
If it is required to change over to manual speed setting an allpication module with two analog
inputs will be additionally required. For programming data please refer to the attached manual.

3.4.3 Programming the DPA 2000S
When using the function „cutting constant“ th e following settings of the parameters need to be
programmed:
(
„Internal parameter setting“ on page 5-36)
P19: Please enter the number of switchings on the fork light barrier per revolution (e. g.
perforated disk with 8 holes = 8 switchings)
P20: Enter the value „1“ (recommended)
NOTE:
The DPA 2000S supports two gear levels. Determine the two gear levels of your lathe in which
you want to use the cutting constant functions. All control values which you have set on the DPA
2000S are this way only referring to this gear level. For another gear level the modified transformation will lead to deviations between the target value and the actual value, in particular for
spindle speeds.
DANGER!
If the lathe is operated in another gear level, the admissible maximum speed can be
exceeded. This way, the retention force of the clamping devices will be reduced when the
centrifugal force is increasing. In doing so, the workpiece might get loose and fly off the
machine.
For your own safety use the cutting constant function only for the two selected gear
levels for which you have specified and entered the parameters.
To do so, determine the minimum and maximum speed of the selected gear levels.
Example:
Nominal speed of the gear level: 900 1/min
Set frequency range on the FC from 10 Hz to 50 Hz
Minimum speed for 10 Hz 180 1/min
Maximum speed for 50 Hz 900 1/min
P21: Enter the value of the maximum speed for the selected gear level 1.
P22: Enter the value of the minimum speed for the selected gear level 1.
P23: Enter the value of the maximum speed for the selected gear level 2.
P24: Enter the value of the minimum speed for the selected gear level 2.
When you have executed the above steps the commissioning of the DPA 2000S is terminated.
Switch over between the manual speed setting and the cutting constant control using the corresponding ON/OFF switch. The two switch settings need to be marked by the function markings
which are being switched.
