Power failure-time deceleration-to-stop function (Pr. 261)
When a power failure or under voltage occurs, the inverter can be decelerated to a stop or can be de-
celerated and re-accelerated to the set frequency.
The above parameter can be set when Pr. 160 "User group read selection" = 0.
Parameter setting
When Pr. 261 is set to "1" or "2", the inverter decelerates to a stop if an undervoltage or power failure
occurs.
Operation outline of deceleration to stop at power failure
When undervoltage or power failure has occurred, the output frequency is decreased and controlled
so that the converter circuit (DC bus) voltage is constant and decreased to 0 Hz to stop.

When under voltage or a power failure occurs, the
inverter can be decelerated to a stop.
2
When under voltage or a power failure occurs, the
inverter can be decelerated to a stop.
If power is restored during a power failure, the
inverter accelerates again.
