Procedure
If there are deviations from normal operation or if faults occur, proceed as follows.
1. Identify the fault using the following table.
You should also take account of the messages of the converter.
2. Rectify the fault using the following table.
SINAMICS S200 PROFINET servo drive system with SIMOTICS S-1FL2
Operating Instructions, 11/2023, FW V6.3, A5E51646752B AB
Fault
Motor does not start
Motor starts slowly
Humming sound when starting
Humming sound in operation
High temperature rise under no-load op‐
eration
High temperature rise under load
High temperature rise of individual wind‐
ing sections
Uneven running
Grinding sound, running noise
Radial vibrations
Axial vibrations
No. Fault cause
A
Overload
B
Interrupted phase in the convert‐
er line supply cable or motor
winding
C
Interrupted phase in the convert‐
er line supply
cable after switching on
D
Converter output voltage too
high, frequency too low
F
Winding short-circuit or phase
short-circuit in stator winding
I
Heat dissipation impeded by de‐
posits
Cooling air inlet or outlet is
blocked by foreign bodies
J
Insufficient shielding for motor
and/or encoder cable
K
Excessive drive controller gain
L
Rotating parts are grinding
Foreign bodies inside the motor
Bearing damage
M
Rotor not balanced

Remedial measures
Reduce load
Check the converter and converter line supply cable, meas‐
ure the winding resistance and insulation resistance, repair
after consultation with manufacturer
Check the converter, converter line supply cable, and the
winding resistance
Check the settings on the converter, perform automatic
motor identification
Measure the winding resistances and insulation resistan‐
ces, repair after consultation with the manufacturer, re‐
place the motor if required
Clean the surface of the servo drive system and ensure that
the cooling air can flow in and out unimpeded
Remove the things that block the inlet or outlet and ensure
that the cooling
air can flow in and out unimpeded
Check the shielding and grounding
Adjust the controller
Determine cause and adjust parts
Replace the motor
For low or medium inertia motors, replace the motor; for
high inertia motors, replace the bearings
Replace the motor
Corrective maintenance
