Q-632 Miniature Rotation Stage MP129E Version: 1.1.2 33
Problem Possible causes Solution
Function impairment
after system
modification
 The electronics
were replaced
 The rotation
stage has been
replaced

Load the Q-632's parameter set from the
positioner database.

If necessary: Set the parameters for the
electronics in PIMikroMove so that they
correspond to the application (load,
orientation) of the Q-632 (see user manual
for the electronics).
No or limited motion The cable is not
connected correctly
or is defective

Check the connecting cable(s)
Excessive load

Reduce the load. Pay attention to the
information in the "Technical Data" section
(p. 37).

Take suitable measures to make sure that
the load exerts a torque that is lower than
the drive torque (p. 37) when the rotation
stage is mounted vertically, e.g., cables
connected to the load should have
sufficient strain relief.
Parameters of the
electronics
incorrectly set

See the "Function impairment after system
modification" problem in this table.
Operating voltage
too low

Provide an operating voltage of 48 V.
Unfavorable
operating frequency
for step mode

Depending on the electronics used: Adapt
the operating frequency for step mode or
the velocity in closed-loop operation (p. 28)
(For details, see the manual for the
electronics).
Warped base body

Mount the Q-632 on a flat surface. The
recommended flatness of the surface is
2 µm.
Unfavorable load
mounting

Pay attention to the maximum torque when
mounting the load (p. 19).

The gap between the center of gravity of
the load and the center of the motion
platform is as small as possible in all
directions.
