Main circuit voltage fault
drive
Meaning: The main circuit DC voltage fluctuates abnormally outside regeneration. This fault is detected when the load is at least 80% of the maximum applicable motor capacity of the drive; (detection occurs when L8-05 is set to valid); loose input power supply wiring terminals; input power supply phase loss; momentary power failure; excessive input power supply voltage fluctuations; unbalanced input phase-to-phase voltages.
