7 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:
A&D Hot-line 0180 50 50 222
For motor / motor components: Contact in the works 0174-3110669
8 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.
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
motor or encoder cables. Check screening and grounding (see
chapter 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.
