No under-voltage avoidance (If under-voltage or power fail,
the motor decelerates to stop. Motor re-accelerates if power
restores during the deceleration to stop.)

Power failure stop function
When 10-33(P.273) is set to 1 or 11, (and 10-09(P.57)=99999), inverter decelerates to a stop when input power fail;
When 10-33(P.273) is set to 2 or 12, inverter decelerates to a stop when input power fail, and if during deceleration
power comes back ON, inverter accelerates again.
Set 10-34(P.274) according to the value of load inertia. If load inertia is larger, then 10-34(P.274) should be set
to a smaller value to produce enough regenerative power, usually 3.00Hz is enough.
Motor decelerates for the time set in 10-36(P.276).( deceleration time is set to the time from 01-09(P.20)
acceleration / deceleration reference frequency to stop.)
