Instructions in case of faults
In case of deviation from normal operation or faults, proceed first according to the following
list:
Contact the works, please also refer to the relevant section of the operating manual for the
components of the entire drive system.
Do not disable the protective devices, even in trial operation.
Consult the manufacturer or the SIEMENS service center when necessary.
For start up, system motor converter:
For motor / motor components:
Fault
Irregular running
Vibrations
Running noises
Motor overheats
(Surface temperature
>140 °C (284 °F))
Temperature monitoring

Inspection, Maintenance, Disposal
Clean wherever and whenever the degree of contamination makes it necessary 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.
When replacing the motor bearings because they have worn, encoders with intrinsic
bearings must also be replaced.
The encoder system must be readjusted each time after the motor has been
disassembled.
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.

Cause
Inadequate screening of the
motor or encoder cables.
Amplification of the drive control-
ler too high
Coupling elements or driven
machine are badly balanced
Inadequate alignment of the drive
train
Fixing screws are loose
Foreign bodies inside the motor
Bearing damage
Drive overloaded
Heat dissipation impaired by
deposits
