Main causes:

1. The harness between the servo board and the power regeneration control board has an open circuit or short circuit.

2. A faulty connector between the servo board and power regeneration control board.

3. A problem with the servo board.

4. A problem with the power supply unit power 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.
