A06250 (F) Infeed: Defective capacitor(s) in at least one phase of line filter
Drive object: A_INF, B_INF, S_INF
Reaction: NONE
Acknowledge: NONE
Cause: A change in the line filter capacitance was detected in at least line phase.
The voltages and phase currents of the line filter, measured using a Voltage Sensing Module (VSM), indicated 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 actual 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 normalization of the line supply voltage measurement using the VSM (p3660).
- check the normalization of the filter current measurement using the VSM (p3670).
- check the line filter capacitors and if required, replace the line filter.

V input CT gain), p3676 (VSM line filter capacitance alarm threshold)
Reaction upon F: NONE (OFF1, OFF2)
Acknowl. upon F: IMMEDIATELY (POWER ON)
A06260 Infeed: Temperature in the line filter too high
Drive object: A_INF, S_INF
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: - ensure the correct and reliable connection of the line filter temperature switch with input X21 of the infeed.
- ensure the connection of the line filter specified for the infeed being used. Check the line filter type (p0220[0]).
- 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. If required, replace the fan.
- defective temperature switch of the filter module. If required, replace the filter module.
F06261 Infeed: Temperature in the line filter permanently too high
Drive object: A_INF, S_INF
Reaction: OFF2 (OFF1)
Acknowledge: IMMEDIATELY
Cause: After the temperature monitoring responded, the temperature in the line filter was permanently exceeded.
Note:
The temperature monitoring is only available for an active interface module.
Remedy: - ensure the correct and reliable connection of the line filter temperature switch with input X21 of the infeed.
- ensure the connection of the line filter specified for the infeed being used. Check the line filter type (p0220[0]).
- 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. If required, replace the fan.
- defective temperature switch of the filter module. If required, replace the filter module.
