官方故障排除步驟
Message value: Drive object: All objects Reaction: NONE (OFF1, OFF2) Acknowledge: IMMEDIATELY (POWER ON) SINAMICS-Alarms Cause: The bypass contactor of the infeed unit was dam aged by being opened (multiple number of times) while it was conducting current. Possible causes: - scheduled opening under load can be necessary, for example, to pr otect the drive converter group in the event of a ground fault in high frequency spindles. - incorrect operator control of the infeed can cause t he contactor to switch under load. If, in spite of a missing operating enable, the infeed unit draws active motoring power from the DC link. Remedy: In order to avoid critically damaging the comple te drive converter group, it is urgently recommended to replace the damaged infeed unit.
