官方故障排除步驟
Type: Resettable Fault Coast Y Y A current path to earth ground greater than 25 % of drive rating has occurred. • Perform a Megger or surge test on a disconnected motor. Replace the motor, if necessary. • Check the output phase current displayed in [In U Phase Curr], [In V Phase Curr], and [In W Phase Curr] (port 10) for an imbalance. [In Gnd Current] (port 10) is the calculated (not measured) ground current based on the phase currents. • If the ground fault happens immediately when the drive is started, view the values of the output phase current parameters (noted in the second bullet) when running the drive with a light load or perform a trending analysis. • Reseat the rating plug and current transducer wiring harness.
