Operation selection at power failure
Power failure stop mode (Pr. 261 = 1 or 11)
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
eration to stop function is invalid and the restart after instantaneous power failure operation
is performed.
After a power failure stop, the inverter will not start if the power supply is switched on with
the start signal (STF/STR) input. After switching on the power supply, turn off the start signal
once and then on again to make a start.
