Single/dual safety circuit settings differ between the power sequence board and MCXX. (Servo board XX) (for E0x series controllers)

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

Content: The settings specifying the number of safety circuits do not match between the DIP switch (SW2-1) on the power sequence board and the jumper (JP2 or JP3) on the power supply unit control board (1VH).

Main causes:

1. The switch settings on the power sequence board or power supply unit control board are incorrect.

2. A problem with the power sequence board.

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

Countermeasures:

1. Check that the DIP switch (SW2-1) setting on the power sequence board matches the jumper (JP2 or JP3) setting on the power supply unit control board. With correct settings:

2. Replace the power sequence board.

3. Replace the power supply unit control board.
