- TTyler RoseAug 5, 2025
If the YASKAWA Industrial Equipment indicates a Main Circuit Undervoltage, it could be due to several reasons: * An open-phase occurred with the input power supply. * A momentary power loss occurred. * The wiring terminals for the input power supply are loose. * The voltage fluctuations in the input power supply are too large. In each of these cases, reset the fault after correcting its cause.
