Instructions for Use
Checking and resurfacing of hold‐
ing brakes by hand
Checking and resurfacing of hold‐
ing brakes by means of the soft‐
ware function
We recommend that you have the bearings replaced by Rexroth.
Connection Cables
Check connection cables for damage in regular intervals and replace them, if
necessary.
Check any optionally present flexible cable tracks for damage and replace
them, if necessary.
WARNING
Do not repair any connection cables provisionally. If the slightest damage is
detected in the cable sheath, you must immediately put the installation out of
operation and replace the connection cable.
Check the equipment grounding conductor for proper connection and tight fit
in regular intervals.
Holding Brake–Commissioning and Maintenance Instructions
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.
