Issue:
Meaning of error code MOFF on the ATV212.
Product Line:
Altivar 21, Altivar 212
Environment:
All serial numbers
Cause:
Drive faulting on under voltage
Resolution:
Code MOFF indicates that the phase-to-phase input voltage is too low. Measure the main circuit supply voltage. If the voltage is normal for the VFD, check the connection of the factory jumper on PO and PA+ terminals. MOFF is an alarm condition and does not put the VFD into a faulted state.
