Holding Brake – Commissioning and Maintenance Instructions
Checking and resurfacing of hold‐
ing brakes by hand
Checking and resurfacing of hold‐
ing brakes by means of the soft‐
ware function

In order to ensure proper functioning of the holding brake, it must be checked
before the motors are commissioned. The test as well as the resurfacing may
be carried out "mechanically by hand" or "automatically by means of the soft‐
ware function".
Measure the holding torque (M4) of the holding brake. If necessary, resurface
the holding brake.
Measuring the Holding Torque (M4) of the Holding Brake
1.
De-energize the motor and secure it against re-energization.
2.
Measure the transferable holding torque of the holding brake with a tor‐
que wrench. For holding torque (M4) refer to the technical data.
If the holding torque (M4) is achieved, the motor is ready for assembly.
If the holding torque (M4) is not achieved, the subsequent resurfacing-
process can be used to reconstitute the holding torque.
Resurfacing the Holding Brake
1.
At closed holding brake, turn the output shaft by hand, e.g. with the help
of a torque wrench, by about 5 revolutions.
2.
Measure the holding torque (M4).
If the holding torque (M4) is achieved, the motor is ready for assembly.
If the specified holding torque (M4) is not attained after several grinding-
in processes, the holding brake is not operable. Please, contact the
Rexroth Service.
Checking the Holding Torque (M4) via P-0-0541, C2100 Command
Holding system check
1.
The efficiency of the holding brake and the opened state are checked by
the control device by starting the routine "P-0-0541, C2100 Command
Holding system check".
If the holding brake is operational, the drive is in an operational state af‐
ter the routine was run through. If the braking torque is too low, the con‐
trol device outputs a corresponding message.
The brake test can also be carried out cyclically in the framework
of a preventive maintenance.
Restoring the Holding Torque (M4) by means of the Software Function
The following possibilities are available:
1.
Realization of the resurfacing routine IndraDrive "Restoring the holding
torque "(see"P-0-0544, C3900 Command Resurfacing of motor holding
brake"). A repeated realization of the resurfacing routine is possible.
Upon the execution of the command C3900 it is not checked whether
the resurfacing of the holding brake was successful. It is recommended
to execute the command C2100 (Command Holding system check)
once again.
2.
Resurfacing routine by superior control. Here, special control programs
adapted to the machine and system concepts are required. If necessary,
please contact your Bosch Rexroth distribution partner and discuss the
resurfacing routine parameters for your application.
