Problem
Possible causes
Solution
P-753 or controller has been
replaced
When using positioners, whose ID chip
(p. 12) does not contain any calibration data,
or LEMO plug connectors, axis displacement
has to be recalibrated after the P-753 or the
controller has been replaced.
Perform a recalibration of the axis
displacement (see controller manual) or
contact our customer service
department (p. 33).
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 is not
connected to the
corresponding controller
(only with several systems)
Pay attention to the assignment of the
devices when several systems are
connected. The assignment is indicated
on the calibration label of the controller
(see rear panel or bottom side), which
contains the serial number of the
positioner to be connected.
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 that occurred with your system is not listed in the table above or cannot be
solved as described, contact our customer service department (p. 33).
