Backup frequency upon abnormality
Default
100.0%
Setting Range
60.0%-100.0%
If a fault occurs during the running of the AC drive and the handling of fault is set to "Continue to run", the AC drive displays alarm
code and continues to run at the frequency set in P9.54.
The setting of P9.55 is a percentage relative to the maximum frequency.

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
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.
