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. 12: 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.
Remark:
The motor must be replaced by a
motor of identical type. This is the only way to
ensure that all adjusted parameters 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.
Disconnect electrical connections
Remark:
Protect electrical connections
from pollution (allowed pollution severty
“2” according to EN 50178:1997).
5.
Replace the motor
Remark:
Observe the machine manu-
facturer's instructions when exchanging
the motor mechanically.
6.
Rebuilt electrical connections
7.
Re-establish the dimensional reference
WARNING
Risk of accidents
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.
