INFORMATION
Systems are calibrated at the factory to achieve optimum performance. Replacing
the system components will cause a loss in performance when Z drives without
ID chip are used, or whose ID chip does not contain any calibration data, or when
Z drives with LEMO connectors or analog controllers are used.
Only P-725.xxD and P-725.xCA Z drives are equipped with an ID chip.
Note the assignment of the Z drive axis to the controller channel, which is given
by the calibration label of the piezo servo controller.
For systems without ID chip:
If the piezo servo controller or the Z drive has to be replaced, recalibrate the axis
displacement (see controller manual) or contact our customer service
department (p. 15).
Starting Up and Operating the P-725
Requirements
You have read and understood the safety precautions (p. 3).
You have read and understood the general notes on startup and operation (p. 13).
Starting up and operating the P-725
Follow the instructions in the user manual of the piezo controller used for startup and
operation of the P-725.
Discharging the P-725
The P-725 must be discharged before demounting. Demounting is necessary e.g., before cleaning or
transporting the P-725 as well as for modifications
Discharging a P-725 that is connected to the controller
In closed-loop operation:
1. Switch off the servo mode on the controller.
2. Set the piezo voltage to 0 V on the controller.
In open-loop operation:
Set the piezo voltage to 0 V on the controller.
Discharging a P-725 that is not connected to the controller
Connect the P-725 to the switched-off PI controller for 10 seconds.
