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.
