The "Release holding brake" service function may only be used
while there is no communication with other drive components or
an engineering tool.
If there is executable communication, the holding system monitor‐
ing command can be used to release the brake (parameter
"P‑0‑0541, C2100 Holding system check command").
Saving Parameters
For servicing, the drive parameters must be saved and archived on initial
commissioning (e.g. with software Rexroth IndraWorks D) because it must be
expected that the parameters of the defective drive cannot be read any lon‐
ger.
Parameters can be managed in the control unit or saved and loaded with the
"Rexroth IndraWorks D" software.
Firmware Update

5.4.5 Maintenance
Maintenance of the Motor Component
General Information
The motors operate in a maintenance-free way within the given operating
conditions and service life. However, operation under unfavorable conditions
can lead to limitations in availability.
● Increase the availability with regular preventive maintenance measures.
Observe the information in the maintenance schedule of the machine
manufacturer and the maintenance measures described below.
Risk of burns by hot surfaces with tempera‐
tures of more than 100 °C!
Before beginning to work, let the motors cool down. The thermal time con‐
stant specified in the Technical Data is a measure for the time required for
cooling down. Cooling down can require up to 140 minutes!
Do not work at hot surfaces.
Wear safety gloves.
Cleaning
Excessive dirt, dust or shavings may affect the function of the motors ad‐
versely, may in extreme cases even cause a failure of the motors. For that
reason, you should clean the cooling ribs of the motors in regular intervals (at
the latest, after one year is over).
Bearings
The nominal service life of the bearings is L10h > 30000 h (according to
DIN ISO 281, ed. 1990), if the permissible radial and axial forces are not ex‐
ceeded.
The motor bearings should be replaced, if
● the nominal bearing service life has been reached
● running noise can be heard
