Digit 1 = 0: When momentary stop is detected, power failure (UV
fault) occurs and the inverter output is shut off.
Digit 1 = 1: If momentary stop time is within momentary assurance
time (see note), the operation continues after the momentary stop.
If the momentary assurance time is exceeded, the inverter output
is shut off.
