PIA Series Inertial Piezo Motor Actuators
4.2 Maintenance
Periodically, the manual knob should be used to move the drive screw from one end
of travel to the other, in order to redistribute the grease. The periodicity will depend on
usage. In applications involving continuous use or where a small travel range is used
at high duty cycle, the grease should be redistributed often to ensure optimal
performance of the actuator.
Due to frictional-inertia nature of the mechanism, wear of the screw coating occurs
during its lifetime. Periodic maintenance helps to increase the optimum stepping
performance during its lifetime.
4.3 Transportation
Caution
When packing the unit for shipping, use the original packing. If this is not
available, use a strong box and surround the unit with at least 20 mm of
shock absorbent material.
