MAF – Coolant Supply
It may become necessary to dismantle the coolant supply for
maintenance measure or troubleshooting.
⇒
This work must be carried out only by qualified personnel.
⇒
Do not carry out any maintenance measures when the machine is
running. Please observe the safety instructions.
⇒
Protect open supply cables and connections against penetration of
pollution.
Maintaining Holding Brakes
In order to ensure proper functioning of the holding brake, it must be
checked before the motor is installed.
Measure the holding torque of the brake, and burn-in the holding brake, if
necessary.
Proceed as follows:
1. De-energize the motor and secure it against re-energization.
2. Measure the transmittable holding torque of the holding brake using a
torque wrench. The holding torque of the brakes is specified in the
data sheets.
3. If the holding torque specified in the data sheets is attained, the
holding brake is ready for operation.
If the holding torque specified in the data sheets
is not attained
, the
holding brake must be burned-in as described in step 4.
4. Burn-in
process:
Recommendation for brake burn-in
Interval
1x
Burn-in speed and duration
100 rpm
/ 30s duration
Procedure
500ms, clocked
Ambient Temperature
–20 °C to +50 °C

If the holding torque specified in the data sheets is attained, the
holding brake is ready for operation.
If the holding torque specified in the data sheets
is not attained
,
repeat steps 4 and 5 of the burn-in process.
If the specified holding torque is not attained after the second burn-in
process, the holding brake is not operable. Notify Bosch Rexroth Service.
If holding brakes are required only sporadically (braking cycle >48 h)
during operation, a film of rust may develop on the brake friction surface.
To prevent the holding torque from dropping below the specified holding
torque, we recommend the burn-in procedure described below:
Recommendation for grinding in
Interval
Once in 48 h
burn-in speed and duration
100 rpm
Number of burn-in revolutions
1
Ambient Temperature
–20 °C to +50 °C
