3-PHASE FAILED

3-phase supply failure.
Cause:

  • Total failure of supply or missing phase.

  • Blown fuses (high-speed thyristor stack or power chassis coding).

  • Incorrect mains voltage for the controller.




Remedy:

  • Check supply to the controller.

  • Check protection fuses.

  • Verify mains voltage against Product Code.
PHASE LOCK

Supply frequency is outside the frequency band limits 45 – 65Hz.
Cause:

5703 RCV ERROR

Invalid data received via P3 port from another Drive.
Cause:

  • Communication error on P3 port.

  • (Alarm only operates when MODE parameter is set to 5703 SLAVE).




Remedy:

  • Check connections on P3 port.
STALL TRIP

Motor stationary with current exceeding STALL THRESHOLD for longer than delay.
Cause:

  • Motor is stalled while current is high.

  • (Alarm only operates when STALL TRIP parameter is enabled).




Remedy:

  • Remove mechanical blockage or adjust stall parameters.
OVER I TRIP

Current feedback value has exceeded 280% of rated current.
Cause:

  • Motor armature windings failure.

  • Badly tuned current loop.
