Features and functions
WARNING
Grievous bodily harm due to dangerous move-
ments from falling or dropping axes!
Secure vertical axes against dropping or sinking
after switching off by e.g.:
−
Mechanical locking of the vertical axis
−
External brake, arrestor, clamping device.
−
Weight compensation of the axes
The holding brake itself is not suitable for per-
sonal protection. Ensure protection of individuals
by superordinate protective measures such as
cordoning off of danger zones using protective
fences or grids.
For European countries, additionally comply with
the following standards and guidelines, e.g.
•
EN 954; ISO 13849-1 and ISO 13849-2
Safety-related parts of control units
•
Information sheet no. 005 Gravity-loaded
axes (vertical axes) published by: DGUV
Fachbereich Holz und Metall (German
Employer's Liability Insurance Association
Wood and Metal)
Determine the safety requirements valid for the
case of application and observe the safety
requirements during plant design. Comply with
national regulations at the installation site of the
system.
Holding brake - commissioning and mainte-
nance instructions
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)
Bosch Rexroth AG
The holding brake functionality can be checked
mechanically by hand (torque wrench) or auto-
matically by means of the software function.
Manually check holding torque (M4)
1. Disconnect the motor from the power
supply and secure it against being
switched on again.
2. Measure the transferable holding torque
(M4) of the holding brake with a torque
wrench.
Check holding torque (M4) automatically
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 ach-
ieved, the resurfacing routine can be
used to reconstitute the holding
torque.

Vibration behavior

The oscillation behavior corresponds to oscil-
lating quantity level A according to DIN EN
60034-14 up to the rated speed.

5.2.10 Bearing

The motors are equipped with a deep-groove ball
bearing with high-temperature grease for prelu-
brication.
