NOTICE
Destruction of the piezo actuator due to rapid cooling or heating!
Cooling down or heating up too quickly leads to a thermomechanical overload that can destroy
the piezo actuator.
Allow the piezo actuator to cool down or warm up slowly.
NOTICE
Uncontrolled oscillation!
Oscillation can cause irreparable damage to the piezo actuator. Oscillation is indicated by a
humming and can be caused by the following:
A change in the load and/or dynamics requires the servo-control parameters to be
adjusted.
The piezo actuator is operated near to its resonant frequency.
If you notice oscillation:
In closed-loop operation, immediately switch off the servo mode.
In open-loop operation, immediately stop the piezo actuator.
INFORMATION
The positive direction of motion (p. 10) corresponds to the expansion direction of the piezo
actuator when a positive voltage is applied.
6.2
Determining the Operating Parameters
INFORMATION
For determination of the the operating parameters, it is assumed that the piezo actuator is
clamped on one side.
If you require operating parameters for unclamped operation of the piezo actuator,
contact our customer service department (p. 47).
