Upon instantaneous power failure or sudden voltage dip, the DC bus voltage of the AC
drive reduces. This function enables the AC drive to compensate the DC bus voltage
reduction with the load feedback energy by reducing the output frequency so as to keep
the AC drive running continuously.
• 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 F9-61, 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.
