Operation selection at power failure Parameter
6 - 166
Power failure stop mode (Pr. 261 = 1)
If power is restored during power failure deceleration, deceleration to a stop is continued and the in-
verter remains stopped. To restart, turn off the start signal once, then turn it on again.

NOTES When automatic restart after instantaneous power failure is selected (Pr. 57 9999), power failure
stop function is made invalid and automatic restart operation after instantaneous power failure is
made valid.
When the power failure deceleration stop function is active (Pr. 261 = "1"), the inverter will not start
even if the power is turned ON with the start signal (STF/STR) ON. After switching on the power,
turn off the start signal once and then on again to make a start.
