Maintenance
NOTICE
Brakes with defective armature plates, socket head cap screws, springs or counter friction
faces must always be replaced completely. Observe the following for inspections and mainte-
nance works:
❚ Contamination by oils and greases should be removed using brake cleaner, or the brake
❚ After replacing the rotor, the original braking torque will not be reached until the run-in oper-

Check the rotor thickness
1. Stop the motor and control system!
2. Remove the motor cover and remove the cover ring, if present.
3. Measure the rotor thickness using a caliper gauge.
4. Compare the measured rotor thickness with the minimally permissible rotor thickness,
5. If required, replace the rotor completely (
