Fault Reset (Setting: 14)
OFF Normal operation
ON Resets faults when input goes from OFF to ON. (Normal operation when no fault has occurred.)
D With this setting, the multi-function input resets faults that have occurred.
D When a fault has occurred, be sure to find out what kind of fault occurred, take steps to correct the cause
of the fault, and restart the Inverter. It is possible to damage the Inverter by repeatedly resetting a fault
without correcting the cause.
D To resume operation after a fault has occurred, turn the run command OFF, turn the fault reset input
from ON to OFF, and then turn the run command ON again. A fault cannot be reset while the run com-
mand is ON.
D If a fault hasn’t occurred, turning the fault reset ON and OFF will have no effect on operation.
