代码 206250: <location>Infeed: Defective capacitor(s) in at least one phase of line filter

Message value: %1 Drive object: A_INF, S_INF Reaction: NONE Acknowledge: NONE Cause: A change in the line filter capacitanc e 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 deviation of the filter capacit ances 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 permissib le 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.
