NOTICE
Uncontrolled oscillation!
Your application and the N-565 can be damaged by uncontrolled oscillation. Uncontrolled
oscillation can be identified by the fact that the positioner approaches the target position too
slowly or too fast or does not keep it stable (servo jitter).
If uncontrolled oscillation occurs during operation of the N-565:

Switch the servo control system of the affected axis off immediately.

Check the settings of the servo control parameters.
INFORMATION
Impact forces can cause encoder malfunction.

Avoid impact force on the positioner.

Do a reference move (refer to the user manual for the controller).
INFORMATION
The positive direction of motion is in the opposite direction of the cable exit.
INFORMATION
The repeatability of the positioning is only ensured when the reference switch is always
approached from the same side. Recommended controllers from PI fulfill this requirement with
their automatic direction detection for reference moves to the reference switch.
6.2 Operating Parameters
If you use the software included in the scope of delivery of the E-861.1A1 controller, the
operating parameters can be loaded from the PIStages3.dat database.

Use the PIUpdateFinder to update the PIStages3.dat database on your PC. The
PIUpdateFinder is included in the software package for the E-861.1A1 controller.
Refer to the user manual for the E-861.1A1 controller for further information on positioner
databases.
