Possible Causes and Remedies
Problem
Possible causes
Solution
Reduced positioning
accuracy
Warped base body
Mount the L-738 / V-738 onto an even
surface. The recommended flatness of the
surface is
≤
5 µm.
Increased wear due to small
motions over a long period of
time
Carry out a maintenance run over the
entire travel range.
Functional impairment
after system
modification
Controller was replaced.
V-738 was replaced by
another model.
Load the parameters from the stage
database that correspond to the
combination of controller and the L-738 /
V-738 model.
Mechanical system
does not move; no
operating noise can be
heard.
Controller not correctly
connected or defective.
Check all connecting cables.
Check the controller.
If necessary, check the power supply of the
stage.
For L-738.0511xx
models: Actual position
deviates from the
displayed position.
The motor is overloaded by an
external load torque or the mass
to be driven in the case of strong
acceleration or deceleration.
The motor skips steps. The information on the
current position is lost without the controller
detecting the state.
Determine the maximum velocity for a
stage with a stepper motor in the
application.
Start a new reference move.
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. 35).
