Version: 1.2.0

PZ244E

P54x Nanopositioner

Problem

Possible causes

Solution

Axes were mixed up during

connection (only with LEMO

connectors)



Pay attention to the assignment of the

axes when connecting the positioner to

the controller. This assignment is

indicated by labels on the devices.

The positioner

starts oscillating

or positions

inaccurately

Servo control parameters

incorrectly set because for

example, the load was

changed

1.

Switch off the servo mode of the

corresponding motion axes immediately.

2.

Check the settings of the servo control

parameters on the controller.

3.

Adjust the servo control parameters on

the controller according to the load

change.

Open-loop operation near

the resonant frequency



In open-loop operation, operate the

positioner only with a frequency that is

below the resonant frequency.

If the problem with your system is not listed in the table above or cannot be solved as

described, contact our customer service department (p. 33).
