Encoder internal fault

What does 7380 mean?

An internal fault occurred within the encoder system of the ACS880 drive. This suggests a problem with the encoder interface module or the drive's internal processing of encoder signals.

• Faulty encoder interface module (FEN-xx) itself.
• Internal communication error or data corruption within the encoder module or between the module and the drive's main control unit.
• Corrupted encoder data processing firmware.
• Transient internal hardware issue on the encoder interface board.

Click steps to track your progress.

1. 1

   Perform a power cycle of the drive and the associated encoder system.

2. 2

   Check the event log for any auxiliary codes that might provide more specific details about the internal fault.

3. 3

   Verify the encoder interface module (FEN-xx) is correctly seated in its slot and its firmware is up to date.

4. 4

   If the fault persists, document all event log details and contact ABB technical support, quoting the auxiliary code.
