■
Remove extraneous objects
Pollution between rotary ring
and stationary plate
■
Dismount the stationary plate
and the rotary ring and clean
the plate and the ring
■
Perform a test run without
rotary ring and stationary plate
During initial commissioning:
The output flange/rotary ring is
subject to mechanical tension
■
Verify that the mounting site

mounting
■
Verify the installation
Output flange overtravels a po-
sition
■
The rotary switch (controller
board) is set to an
excessively high stop delay
time

If the position is overtraveled
from time to time (but at an
increasing frequency), this
may be caused by contact
erosion or wear of the holding
brake.
