Troubleshooting
The positioner does not move
Cable not connected correctly
►
Check the cable connections.
The electronics or mechanics were replaced
►
Run the
once again.
Electronics not connected correctly
►
Check all connecting cables (p. 19)
.
Defective electronics
►
Check the electronics.
Excessive load
►
Reduce the acceleration and velocity.
►
Adapt the servo-control parameters, see the
user manual for the electronics.
►
.
Motion platform has triggered the limit
switch
►
If you are using a controller from PI: Switch on
the servo mode for the affected axis again in the
PC software.
►
Command the axis to move away from the limit
switch.
The positioner was connected to the switch-
ed-on electronics
►
Switch the electronics off and on again or restart
them with the
RBT
command or with the corre-
sponding PC software function.
Incorrect configuration
►
Check the V-412.xx6025E0's parameter settings
in the electronics connected and make the ap-
propriate corrections.
Incorrect command or incorrect syntax
►
Send the
ERR?
command in the PI electronics
and check the error code .
Incorrect axis or channel commanded
►
Make sure that the electronics use the correct
axis respectively channel identifier.
Reduced positioning accuracy
Warped base body
►
Mount the V-412.xx6025E0 onto an even sur-
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-412.xx6025E0
►
Switch off the servo control system or the con-
troller immediately.
►
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.
