When fault occurs, the inverter displays A** and stops.
2: Continue running
When fault occurs, the inverter continues to run and displays A**. The running frequency is set
in P9-54.

Upon instantaneous power failure, the DC bus voltage of the inverter will reduce. The function
compensates the DC bus voltage reduction with the load feedback energy by reducing the
output frequency so as to keep the inverterrunning continuously.
If P9-59 = 1, upon instantaneous power failure, the inverter decelerates. Once the bus voltage
resumes to normal, the inverter 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, the inverter decelerates to stop.
