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
