Check/run in the holding brake
Occasional braking with a shifted load helps conserve the holding brake's holding torque. If the holding brake
produces no mechanical work over a prolonged period (braking with a shifted load), some parts of the
holding brake can corrode or other deposits can accumulate and thus reduce the holding torque.
The holding brake has been run in on leaving the factory. If the holding brake produces no mechanical work
over a prolonged period, some parts of the holding brake can corrode. If the holding brake should not
demonstrate the holding torque specified in the technical specifications, it would need to be run in again:
=> The motor is not mounted. The holding brake is engaged.
=> Measure the brake holding torque using a torque wrench.
=> Compare the value with the holding torque indicated on the technical data sheet.
=> If the holding torque is markedly different from the stated values, turn the motor shaft by hand 25 turns in
both directions.
=> Repeat the operation. If the holding torque has not been restored after 3 repeat operations, please
contact your vendor.
6.4.Replacing the Motor
