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.

tional description "Rexroth IndraDrive Firmware for Drive Control Devices
