11 Disassembly and
exchange
11.1

Tools required

NOTICE
Motor damage due to strikes onto the motor shaft
−
Do not strike the shaft end and do not
exceed the allowed axial and radial forces
of the motor.
Use suitable tools when disassembling transmis-
sion elements.
Pulling off
Fig. 21: Remove transmission element
Use tools suitable for pulling off. Use a shim to
protect the shaft end when using pulling-off tools.
Heat the output element, if necessary.
11.2

Replace the motor

WARNING
Electric shock due to live parts with more than
50 V!
Replacement may only be performed by per-
sonnel trained and qualified to work on or with
electrical equipment.
Bosch Rexroth AG
MS2E Synchronous Servomotors
The motor should be replaced by a motor of
identical type. This is the only way to ensure that
all parameterizations can remain unchanged. :
1. If necessary, note the previous absolute
value
2. Open the main switch
3. Make sure the main switch cannot be
switched back on
4. Disconnection plug connections
When exchanging the motor, close open
plug sides of power connections with pro-
tection caps if moistening with coolant/
lubricant or soiling must be expected
(allowed soiling degree 2 according to EN
50178).:
5. Replace the motor
Observe the machine manufacturer's
instructions when exchanging the motor
mechanically.:
6. Re-establish the plug connections
7. Re-establish the dimensional reference
WARNING
due to unintentional axis movements! : If
servo axes are provided with an indirect
position measuring system via the motor
encoder, the dimensional reference is lost
after motor replacement!
Restore dimensional reference to the
machine coordinate system after replacing
the motor.
11.3 Preparing storage
Before storing motors, the protective covers
attached to the motor at the time of delivery must
be attached to connectors on the shaft.
