Maintenance Intervals For The Brake; Adjusting The Air Gap - Siemens SINAMICS G115D Operating Instructions Manual

11.2.20.2

Maintenance intervals for the brake

For safe and trouble-free operation, check and maintain the spring-operated brake at regular
intervals.
For operational braking, the maintenance intervals depend on the loading on the brake in the
application. Take all causes of wear into account when calculating the maintenance intervals.
Siemens AG recommends a regular inspection at fixed time intervals for low loaded brakes,
e.g. holding brakes with an emergency stop.
Failure to maintain the brake can lead to operating faults, production outage or damage to
the plant. Specify a maintenance plan for each application that is appropriate to the
operating conditions and loading of the brake. The maintenance intervals and maintenance
work for the pneumatic brake are listed in the table.
