valid for the specific case of application and
observe them during plant design. Comply with
all applicable national regulations!

WARNING
Danger of explosion at maintenance work and
check operation
Do maintenance work only outside of hazardous
areas.
Ensure that no hazardous gas or dust atmos-
phere exists during grind in procedures.
That is why the function and the holding brakes
have to be checked in regular intervals and mal-
functions must be removed in an appropriate
period.
The braking effect can be reduced by:
•
Corrosion on friction surfaces, vapor and
sediment
•
Over voltages and too high temperatures
•
Wear (increasing the air gap between arma-
ture and pole)
The holding brake functionality can be checked
mechanically by hand or automatically by means
of the software function.
Manually check holding torque (M4)
1.
De-energize the motor and ensure it
cannot be restarted.
R911414374, Edition 01
2.
Measure the transferable holding torque
(M4) of the holding brake with a torque
wrench.
Check holding torque (M4) using the soft-
ware function
For Bosch Rexroth drive controller
Start the P-0-0541, C2100 Command
Holding system check in drive controller.
The efficiency of the holding brake and the
opened state are checked by starting the
routine.
�� If the holding torque (M4) is not
achieved, the resurfacing routine can
be used to reconstitute the holding
torque. If you have any questions about
grind in parameters, contact Bosch
Rexroth service.
6.2.9
Vibration behavior
The oscillation behavior corresponds to oscil-
lating quantity level A according to EN IEC
60034-14:2018 up to the rated speed.
6.2.10 Bearing
The motors are equipped with a deep-groove ball
bearing with high-temperature grease for prelu-
brication.
Bearing service life
The bearing lifetime is an important criterion for
the availability of motors. The operating condi-
tions influence the bearing service life L
siderably.
