8 Troubleshooting

P-88x/P-08x Piezo Actuator

PZ259E

Version: 1.1.0

43

Problem

Possible causes

Solution

No or limited motion

Cable not connected correctly



Check the cable connections.

Excessive load



Do not exceed the maximum

compressive/tensile stress

capacity (p. 51).

Piezo actuator is depolarized due

to overheating or reverse

polarity



Contact our customer

service department (p. 45).

Piezo actuator moves in

the opposite direction to

that specified when

voltage increases

Reverse polarity of the piezo

actuator



Contact our customer

service department (p. 45).

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. 45).
