PZ245E
P-2x5 Piezo Actuator
Problem
Possible causes
Solution
Reduced
accuracy
P-2x5 or controller has
been replaced
Recalibrate the axis displacement (see
controller manual) or contact our customer
service department (p. 39).
Axes were mixed up
during connection
With calibrated systems:
Pay attention to the assignment of the axes
when connecting several piezo actuators to a
multi-channel controller. This assignment is
indicated by labels on the devices.
The piezo
actuator starts
oscillating or
positions
inaccurately
Servo control parameters
wrongly set because for
example, the load was
changed
1.
Switch off the servo mode of the
corresponding axes immediately.
2.
Check the servo control parameter settings on
the controller.
3.
Adjust the servo control parameters on the
controller according to the load change.
Operating with an
excessively high frequency
Operate the piezo actuator at a maximum of
one third of the resonant frequency.
- Maximum operating frequency of the
unloaded piezo actuator: Refer to "Maximum
Ratings" (p. 43).
- Maximum operating frequency of the loaded
piezo actuator: Refer to "Calculating the
Maximum Operating Frequency of the Loaded
Piezo Actuator" (p. 31).
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. 39).
