INFORMATION
Sound and vibration (e.g., footfall, knocks) can be transmitted to the P-62x and can affect its
performance with regard to position stability.
Avoid sound and vibration while the P-62x is being operated.
INFORMATION
The expansion of the piezo actuators depends on the ambient temperature and can vary by up
to 20 % in the given temperature ranges.
6.2
Operating the P-62x
Follow the instructions in the manual for the electronics (p. 15) used for startup and
operation of the P-62x.
6.3
Discharging the P-62x
The P-62x must be discharged in the following cases:
Before Installation
When the P-62x is not in use but the electronics remain switched on to ensure
temperature stability
Before demounting (e.g., before cleaning and transporting the P-62x and for
modifications)
The P-62x 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.
