PZ247E
P-63x Nanopositioner
The P-63x is driven by piezo actuators. Temperature changes and compressive stress can induce
charges in piezo actuators. Piezo actuators can remain charged for several hours after
disconnecting the electronics. Touching or short-circuiting the contacts in the P-63x's connector
can lead to minor injuries from electric shock. The piezo actuators can be destroyed by an
abrupt contraction.
Do
not
open the P-63x.
Discharge the positioner's piezo actuators before installing:
Connect the positioner to the switched-off PI electronics equipped with an internal
discharge resistor.
Do
not
pull the plug connector out of the electronics during operation.
Touching the contacts in the plug connector can lead to an electric shock (max. 130 V DC) and
minor injuries.
Do
not
touch the contacts in the plug connector.
Use screws to secure the positioner's connector against being pulled out of the
electronics.
If a protective earth conductor is not or not properly connected, dangerous touch voltages can
occur on the P-63x in the case of malfunction or failure of the system. If there are touch
voltages, touching the P-63x can result in minor injuries from electric shock.
Connect the P-63x to a protective earth conductor (p. 16) before starting.
Do
not
remove the protective earth conductor during operation.
If the protective earth conductor has to be removed temporarily (e.g., in the case of
modifications), reconnect the P-63x to the protective earth conductor before restarting.
Mechanical forces can damage or misalign the P-63x.
Avoid impacts that affect the P-63x.
Do
not
drop the P-63x.
Do
not
exceed the maximum permissible stress and load capacities according to the
specifications (p. 33).
Do
not
touch any sensitive parts (e.g., motion platform) when handling the P-63x.
The P-63x is maintenance-free and achieves its positioning accuracy as a result of the optimal
alignment of mechanical components and piezo actuators. Loosened screws cause a loss in
positioning accuracy.
Loosen screws only when instructed in this manual.
Do
not
open the P-63x.
