Starting Up And Operating The P-725; Discharging The P-725 - PI PIFOC P-725 series User Manual

Page 14 / 25
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.
