34 Version: 1.0.0 PZ103E P-73x Nanopositioners
Problem Possible Causes Solution
P-73x or controller
has been replaced When stages, whose ID chip (p. 13)
does not contain any calibration data, or
analog controllers are used, the axis
displacement has to be recalibrated after
the P-73x or the controller has been
replaced.

Perform a recalibration of the axis
displacement (see controller
manual) or contact our customer
service department (p. 35).
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 is
positioned
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 it
