6.3 Discharging the P-56x
The P-56x must be discharged in the following cases:
Before installation
If the P-56x is not used but the controller remains switched on to ensure
temperature stability
Before demounting (e.g. before cleaning and transporting the P-56x and for
modifications)
The P-56x is discharged through the internal discharge resistor of the controller from
PI.
Discharging a P-56x 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-56x that is not connected to the controller
Connect the stage to the switched-off controller from PI.
