Parameter
Power failure stop mode (Pr. 261 = 1)
If power is restored during power failure deceleration, deceleration to a stop is continued and the
inverter remains stopped. To restart, turn off the start signal once, then turn it on again.

NOTES
failure stop function is made invalid and automatic restart operation after instantaneous
power failure is made valid.
After a power failure stop, the inverter will not start even if the power is restored with the start
signal (STF/STR) input. After switching on the power, turn off the start signal once and then
on again to make a start.
