Fault Reset (Setting: 14)

OFF
Normal operation
ON
Resets faults when input goes from OFF to ON. (Normal operation when no fault has occurred.)
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
D
of the fault, and restart the Inverter. It is possible to damage the Inverter by repeatedly resetting a fault
without correcting the cause.
To resume operation after a fault has occurred, turn the run command OFF, turn the fault reset input
D
from ON to OFF, and then turn the run command ON again. A fault cannot be reset while the run com-
mand is ON.
If a fault hasn't occurred, turning the fault reset ON and OFF will have no effect on operation.

The control method, V/f characteristics, and motor constants recorded in the Inverter can be
•
switched by setting "16" (motor switch command) for a constant from H1-01 to 06 (multi-function
inputs), and then inputting a signal while the motor is stopped.
