[Power sequence board] Power supply abnormality signal input from servo board XX. (for E0x series controllers)

Error handling: Motor power OFF.
Error reset: Possible.

Description: The DC supply voltage on the servo board has dropped.

Main causes:

1. Incorrect voltage adjustment of the control power AVR.

2. A problem with the control power AVR.

3. A problem with the servo board.

4. A problem with the power sequence board.

5. The harness between the servo board (X501) and the motherboard (X207) has an open circuit or poor connection.

6. A problem with the motherboard.

Countermeasures:

1. Check the 5V voltage between the test pins on the power sequence board and adjust it to within 5.05 to 5.15V.

2. Replace the control power AVR.

3. Replace the servo board.

4. Replace the power sequence board.

5. Check the harness between the servo board (X501) and motherboard (X207) for open circuits or poor connections.

6. Replace the motherboard.
