Problem
Possible Causes
Solution
Reduced positioning
accuracy
Mounting screw not tight
enough or overtightened
Tighten the mounting screw with a
maximum torque of 0.3 Nm.
Functional impairment
after system modification
Motor controller has been
replaced
Motor controller from PI:
Load the parameters from the stage
database that correspond to the
combination of motor controller and
M-232 model (p. 29).
Motor 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 connector cable.
Lateral forces are affecting
the pusher.
Lateral forces increase the friction on the
internal drive components.
Avoid lateral forces on the pusher of the
M-231.
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
Motor 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 motor
controller for the limit switch processing.
If the problem that occurred with your system is not listed in the table above or it
