Problem
Possible Causes
Solution
P-56x, controller,
extension cable or
adapter cable has
been replaced
When stages, whose ID chip (p. 14) does not
contain any calibration data, or LEMO
connectors (no ID chip lines present) are
used, the axis displacement has to be
recalibrated after the P-56x, the controller, an
extension cable or an adapter cable has been
replaced.
Perform a recalibration of the axis
displacement (see controller manual) or
contact our customer service department
(p. 37).
Axes were mixed up
during connection
(only with LEMO
connectors)
Observe the assignment of the axes when
connecting the stage to the controller.
This assignment is indicated by labels on
the devices.
The stage
starts
oscillating or
positions
inaccurately
Servo-control
parameters incorrectly
set because e. g. the
load was changed
1. Immediately switch off the servo mode of
the corresponding stage axes.
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, only operate the
stage with a frequency that is below the
resonant frequency.
If the problem that occurred with your system is not listed in the table above or cannot
be solved as described, contact our customer service department (p. 37).
