[Servo board XX] IO24V drop. (for E0x series controllers)

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

Content: A decrease in the I/O 24V supply voltage generated by the servo board has been detected.

Main causes:

1. The input/output 24V wiring has a ground fault or short circuit.

2. The 24V supply voltage of the control power AVR has decreased.

3. An open circuit in the 24V wiring.

4. A problem with the servo board.

Countermeasures:

1. Check the input/output 24V wiring (such as the machine harness, X3 signal harness, and harness connected to connector X9 on the power sequence board) for ground faults or short circuits.

2. Check the AVR 24V power supply and replace the AVR if necessary.

3. Check the 24V power wiring.

4. Replace the faulty servo board.
