Problem
Possible causes
Solution
Axes were mixed up during
connection (LEMO
connectors only)
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.
