Holding brake
The brakes need to be checked on a regular basis to ensure safe and trouble−free operation.
The necessary maintenance intervals primarily depend on the stress to which the brake is
subjected in an application. When a maintenance interval is being calculated, all causes of
wear must be taken into account (see notes "Wear on spring−applied brakes"). In the case
of brakes which are subjected to low levels of stress, e.g. holding brakes with emergency
stop function, regular inspections at a fixed time interval are recommended. In order to
reduce the amount of work involved in maintenance, perform the inspection at the same
time as other maintenance work carried out cyclically on the machine if possible.
If the brakes are not properly serviced, operating faults, production outages or damage to
machinery can occur. A maintenance concept adapted to the operating conditions and the
stresses to which the brakes are subjected must therefore be drawn up for every
application. For brakes, the maintenance intervals and servicing work listed in the
following table are necessary.
Maintenance interval for holding brake with
emergency stop Maintenance work
At least every 2 years Inspection of the brake integrated in the motor:

Shorter intervals in the case of frequent emergency
stops!
