[Servo board XX] DC power supply abnormality. (5V) (for E0x series controllers)

Error handling: Motor power OFF.
Error reset: Not possible.

Content: The 5V supply from the control power AVR to the servo board is outside the rated value.

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. The power module board is faulty.

5. A problem with the power supply unit (power supply unit control board).

6. The 5V power supply wiring has a ground fault or short circuit.

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 AVR.

3. Replace the faulty servo board.

4. Replace the servo amplifier unit.

5. Replace the power supply unit control board.
