P54x Nanopositioner
b)
Change the output voltage on channel 2 and channel 3 inversely to the output
voltage on channel 1. The voltage change on channel 2 and channel 3 may only be
half as large as the voltage change on channel 1.
Example:
If you increase the voltage on channel 2 and channel 3 from 50 V DC to 70 V
DC, the voltage on channel 1 must be decreased from 50 V DC to 10 V DC at the same
time.

Discharging the P54x
The P-54x must be discharged in the following cases:
Before Installation
When the P-54x is not in use but the electronics remain switched on to ensure
temperature stability
Before demounting (e.g., before cleaning and transporting the P-54x and for
modifications)
The P-54x is discharged via the discharge resistor inside the electronics from PI.
Discharging a positioner connected to the electronics
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 electronics.
Discharging a positioner not connected to the electronics
Connect the positioner to the switched-off electronics from PI.
