Infeed: Defective Capacitor(S) In At Least One Phase Of Line Filter; Infeed: Temperature In The Line Filter Too High - Siemens Sinamics S120 Diagnostic Manual

206250 <location>Infeed: Defective capacitor(s) in at least one phase of line filter
Message value: %1
Drive object: AFE_SINUMERIK_828, SIC_COMBI, SIC_SINUMERIK_828
Reaction: NONE
Acknowledge: NONE
Cause: A change in the line filter capacitance was detected in at least one line phase.
The voltages and phase currents of the line filter, measured using a Voltage Sensing Module (VSM), indicate a devi-
ation of the filter capacitances from the value parameterized in p0221.
A change or a defect of the line filter capacitors results in a shift of the resonant frequencies and can result in severe
damage to the drive system.
Alarm value (r2124, floating point):
The calculated present capacitance in µF (rounded-off to an integer number).
The 1st decimal point specifies the number of the phase (1, 2, 3) where the capacitance deviates from the specified
value.
Remedy: - check the parameterized value of the filter capacitance (p0221).
- check the correct wiring of the Voltage Sensing Module (VSM):
Differential voltages u12 and u23 must be present at the 100 V/690 V inputs of the VSM; the phase currents of the line
filter must be connected to the 10 V inputs through a current - voltage converter.
- check the alarm limits for the permissible filter capacitance deviation (p3676).
- check the scaling of the line supply voltage measurement using the VSM (p3660).
- check the scaling of the filter current measurement using the VSM (p3670).
- check the line filter capacitors and if required, replace the line filter.

206260 <location>Infeed: Temperature in the line filter too high
Message value: -
Drive object: AFE_SINUMERIK_828, SIC_COMBI, SIC_SINUMERIK_828
Reaction: NONE
Acknowledge: NONE
Cause: The temperature monitoring in the line filter has responded.
If the temperature remains too high during the complete monitoring time, this results in fault F06261.
Note:
The temperature monitoring is only available for an Active Interface Module.
Remedy: - check whether the line filter type set in p0220[0] matches the line filter that is actually connected. Ensure that the line
filter specified for the infeed being used is connected or correct the setting of the line filter type in P0220[0].
- temperature monitoring is mandatory for AIM line filters (refer to P0220). Ensure that the line filter temperature switch
is correctly and reliably connected to input X21 of the infeed.
- reduce the ambient temperature of the line filter.
- reduce the load on the infeed and the filter module.
- check the magnitude of the line supply voltage.
- the internal fan of the filter module is defective. Replace the fan if necessary.
- defective temperature switch of the filter module. Replace the filter module if necessary.
