Inspection, maintenance, disposal
Clean according to the degree of local contamination in order to ensure that the waste heat
is adequately dissipated.
As the operating conditions vary greatly, one can only cite general intervals for fault-free
operation.
Guidelines:
- Bearing service life 20,000 hours
- Radial shaft seals approx. 5,000 hours with oil lubrication.
Dispose of the motor in accordance with the national and local regulations in the standard
recycling process or return it to the manufacturer.
Dispose of the encoder electronics properly as electronic scrap.
Fault
Cause
Remedy
Irregular running
Inadequate screening of the

Check screening and grounding (see
Section 5.1)
Amplification of the drive control-
ler too high
Adjust controller (see converter operat-
ing manual)
Vibrations
Coupling elements or driven
machine are badly balanced
Rebalance
Inadequate alignment of the drive
train
Realign the machine set
Fixing screws are loose
Check and tighten screw connections
Running noises
Foreign bodies inside the motor
Repair by the manufacturer
Bearing damage
Repair by the manufacturer
Motor overheats
(surface temperature
> 140 °C (284 °F))
Temperature monitoring
responds
Drive overloaded
Check load (see type plate)
Heat dissipation impaired by
deposits
Clean surface of drives.
Ensure that the cooling air can flow
freely in and out
NOTICE
The encoder system must be readjusted each time after the motor has been
disassembled.
