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.
For more detailed information about software functions refer to the func‐
tional description "Rexroth IndraDrive Firmware for Drive Control Devices
MPx-xx, DOK-INDRV*-MP*-xxVRS**-FKxx-EN-P."
Maintenance of the Electronic System of the Drive
The electronic system of the drive (power section and control section) oper‐
ates without wear within the given operating conditions and service life. How‐
ever, operation under unfavorable conditions (e.g. increased ambient temper‐
ature) can lead to limitations in availability.
Risk of burns by hot surfaces with tempera‐
tures of more than 60 °C!
After switching the devices off, wait 15 minutes to allow them to cool down
before touching them. Do not work at hot surfaces.
In regular intervals (at the latest, after one year is over), check the heat sink
of the electronic system of the drive for accumulated dirt (e.g. dust deposits).
Remove accumulated dirt.
