Page: 30 / 44

9 Troubleshooting
The V-408 does not move, no operating noise can be heard
Defective electronics ►
Check the electronics.
Electronics not connected correctly ►
Check all connecting cables (p. 23) .
Excessive load ►
Reduce the acceleration and velocity.
►
Adapt the servo-control parameters, see the
user manual for the electronics.
►
Reduce the load, see "Specifications" (p. 33) .
Excessive counterforces in the direction of
motion ►
Reduce the counterforces in the direction of mo-
tion.
Transport safeguard has not been removed ►
Remove the transport safeguard (p. 13) .
When operating with the C-891 controller:
Overheating protection was activated ►
Wait a few minutes until the positioner has
cooled down.
►
Restore operational readiness of the system; see
documentation for the controller.
When operating with the C-891 controller:
Overcurrent protection was activated ►
Restore operational readiness of the system; see
documentation for the controller.
►
Reduce the acceleration and/or velocity in the
application; see documentation for the control-
ler.
Reduced positioning accuracy
Warped base body ►
Mount the V-408 onto a flat surface (p. 14) .
Lateral forces on motion platform too high ►
Avoid lateral forces on the V-408's motion plat-
form.
Target position is approached too slowly or
with overshoot ►
Check whether the servo control parameter set-
tings correspond to the selected closed-loop
control mode; see user manual for the controller.
►
If necessary, correct the settings of the servo
control parameters.
The target position is not kept stable due to
inappropriately set speed / acceleration ►
Correct the corresponding servo control parame-
ter settings (see the user manual for the control-
ler).
Uncontrolled oscillation
Large changes to the load or the alignment
of the V-408 ►
Switch off the servo control system or the con-
troller immediately.
►
Check whether the servo control parameter set-
tings correspond to the selected control mode;
refer to the user manual for the controller.
►
If necessary, correct the settings of the servo
control parameters.
Increased wear
Increased wear due to small motion over a
long period of time ►
Perform a maintenance run (p. 28) .
Traveling to the hard stop with maximum
force ►
Ensure that the end of the travel range is ap-
proached at low velocity and with low force.
