官方故障排除步驟
Type: Resettable Fault Coast Y Y The converter input ground current (peak) has exceeded the threshold set P16 [Gnd Cur Flt Lvl] (port 11) for 5 line cycles. A possible internal short in the drive between a phase, ground, or the DC bus can have occurred. • Verify that the current transducer wiring harness is connected to the converter gate firing board and that they are functioning properly. If necessary, replace all three current transducers (CTs). • If the current transducer wiring harness is connected and the CTs are functioning properly, replace the converter gate firing board. • To determine if there is an imbalance between the phases, view the input phase current values in [Cn L1 Phase Curr], [Cn L2 Phase Curr], and [Cn L3 Phase Curr] (port 11). [Cn Gnd Current] (port 11) is the calculated (not measured) ground current based on the phase currents. If necessary, use trending when the ground fault occurs upon drive power-up.
