6 Starting and Operating
24 Version: 1.1.0 PZ266E P-88x.x5 Piezo Actuator
NOTICE
Damage due to steep edges in the control signal!
If the actuator does not have a preload, steep edges in the control signal can trigger strong
dynamic forces which damage the piezo actuator. Steep edges can occur, for example, when
digital wave generators are switched on.

Avoid steep edges in the control signal on actuators with low preload.
NOTICE
Damage after reconnecting due to a charged piezo actuator!
The piezo actuator can remain charged when the connecting cable of the piezo actuator is
pulled out of the electronics during operation. Reconnecting a charged piezo actuator to
electronics during operation can cause a mechanical impulse that will damage the piezo
actuator.

Do not pull the connecting cable of the piezo actuator out of the electronics during
operation.
If the connecting cable of the piezo actuator was accidentally pulled out of the electronics
during operation:

Discharge the piezo actuator accordingly before reconnecting (p. 30).

Switch off the electronics before you reconnect the piezo actuator.
NOTICE
Reduced lifetime of the piezo actuator due to permanently high voltage!
Applying a continuous high static voltage to piezo actuators reduces the lifetime of the piezo
ceramic.

When the P-88x.x5 is not in use but the electronics remain switched on to ensure
temperature stability, discharge the P-88x.x5 (p. 30).

If possible: Limit the maximum operating voltage during continuous operation.

Reduce offset voltages to a minimum.
NOTICE
Operating voltage excessively high or incorrectly connected!
Operating voltages that are too high or incorrectly connected can cause damage to the
P-88x.x5.

Do not exceed the operating voltage range (p. 40) for which the P-88x.x5 is specified.

Operate the P-88x.x5 only when the operating voltage is properly connected; see
"Connecting the P-88x.x5 to the Electronics" (p. 21).

If you have applied the operating voltage with the wrong polarity accidentally, contact our
customer service department (p. 37).
