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 ISO 13849-1:2015 "Safety of machi-
nery - Safety-related parts of control sys-
tems - Part 1: General principles for
design (ISO 13849-1:2015)" and EN ISO
13849-2:2012 "Safety of machinery. Safety-
related parts of control systems. General
principles for design"

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.
Commissioning and maintenance instruc-
tions
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 (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
achieved, the resurfacing routine can
be used to reconstitute the holding
torque. Contact the Rexroth service
department.
5.2.9
Vibration behavior
The oscillation behavior corresponds to oscil-
lating quantity level A according to EN IEC
60034-14:2018 up to the rated speed.
5.2.10 Bearing
The motors are equipped with a deep-groove ball
bearing with high-temperature grease for prelu-
brication.
