Note: 1. This function is invalid when the automatic restart after instantaneous power failure function is
activated.
2. If (output frequency at occurrence of undervoltage or power failure) minus (frequency set in
Pr. 263) is negative, the calculation result is regarded as 0Hz.
3. The power failure stop function is not activated during a stop or error.
4. If power is restored during deceleration, the inverter is kept decelerating to a stop.
To restart, switch off the start signal once, then switch it on again.
5. When the high power factor converter is used (Pr. 30 = 2), this function is made invalid.
CAUTION
If power-failure deceleration operation is set, some loads may cause the inverter to trip and
the motor to coast.
If enough regenerative energy is not given by the motor, the motor will coast.
