M-235 Linear Actuators MP106E Version: 1.2 33
Problem Possible Causes Solution
Reduced positioning
accuracy Mounting nut is fastened too
tight

Tighten the mounting nut to a
maximum torque of 1 Nm.
Drive damaged due to torque
on pusher

Contact our customer service
department
Functional impairment
after system modification

Controller has been
replaced

M-235 has been replaced
with another model
Controller from PI:

Load the parameters from the stage
database that correspond to the
combination of controller and M-235
model (p. 29).
Controller from a third-party supplier:

Check the operating parameters
The mechanical system
does not move The cable is not connected
correctly or is faulty

Check the connecting cable.
Lateral forces are affecting the
pusher Lateral forces increase the friction on
the internal drive components.

Avoid lateral forces on the tip and
on the pusher of the M-235.
The mechanical system
does not move, but
generates operating
noise Values for the velocity,
acceleration and/or load are too
high

Reduce the velocity.

Reduce the acceleration.

Reduce the load on the mechanical
system.
The mechanical system
did not stop in time and
ran into the hard stop

Velocity is too high (see
chapter Limit Switches
p. 12)

Limit switch is defective

Controller ignores the limit
switch signal
1. Stop the motor.
2. Command the mechanical system
away from the hard stop.
3. Check the settings of the controller
for the limit switch processing.
If the problem that occurred with your system is not listed in the table above or it
cannot be solved as described, contact our customer service department (p. 35).
