Startup and operation
For startup and operation of the drive, follow the instructions in the manual of the
electronics used.
Discharging the N-331
The drive must be discharged in the following cases:
Before installation
If the drive is not used but the electronics remains switched on to ensure temperature
stability
Before demounting (e.g., before cleaning and transporting the drive and for
modifications)
The drive is discharged through the internal discharge resistor of the electronics from PI.
Discharging an N-331 that is connected to the electronics
In closed-loop operation:
1.
Switch off the servo mode on the electronics.
2.
Set the piezo voltage to 0 V on the electronics.
In open-loop operation:
Set the piezo voltage to 0 V on the electronics.
Discharging an N-331 that is not connected to the electronics
Connect the drive to the switched-off electronics from PI.
Maintenance
General Notes on Maintenance
NOTICE
Misalignment from loosening screws!
The drive is maintenance-free and achieves its positioning accuracy as a result of the optimum
alignment of mechanical components and piezo actuators. Loosened screws cause a loss in
positioning accuracy.
Only loosen screws according to the instructions in this document.
Do
not
open the drive.
