What to do if Mitsubishi Electric MELSEC FX Controller shows set value backup error flag?
- GGloria WarrenAug 2, 2025
If the Mitsubishi Electric Controller displays a set value backup error flag, try turning the power off and then on again to see if the issue resolves. This error may be caused by noise or a failure in the 4LC. If the problem persists, it is recommended to consult a Mitsubishi Electric distributor.
