[MCXX] MC control board Motor ON output error. [Output current and current feedback do not match] (Servo board XX) (Code: XX) (for E0x series controllers)

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

Description: A mismatch between the output current state and current feedback was detected at the motor ON output section on the power supply unit control board (1VH).

Main causes:

1. The power supply unit control board is faulty.

2. The wiring between the X320 connectors (24V brake power supply system) on the power supply unit control board has a poor connector connection, open circuit, or similar fault.

3. A problem with the power supply unit power board.

4. A problem with the Motor ON output system (X313 connector section) from the power supply unit. (Note: A jumper is connected between A1-B1 by default.)

Countermeasures:

1. Replace the power supply unit.

2. Check the wiring connected to X320.

3. Replace the motherboard.

4. Check the motor ON output system (X313 connector section) from the power supply unit for short circuits, open circuits, etc.
