If P9-59 = 1, upon instantaneous power failure or sudden voltage dip, the AC drive decelerates.
Once the bus voltage resumes to normal, the AC drive accelerates to the set frequency. If the bus
voltage remains normal for the time exceeding the value set in P9-61, it is considered that the bus
voltage resumes to normal.
•
If P9-59 = 2, upon instantaneous power failure or sudden voltage dip, the AC drive decelerates
to stop.
