Main causes:

1. An open or short circuit in the harness between the servo board and power regeneration control board.

2. The harness between the servo board and the power regeneration control board has a poor connection.

3. A problem with the servo board.

4. A problem with the power regeneration control board.

Countermeasures:

1. Check the harness between the servo board and power regeneration control board for an open circuit, short circuit, or connector connection problem.

2. Replace the servo board.

3. Replace the power regeneration unit.
