If a fault occurs during the running of the inverter and the manner of solving the fault is set
to "Continue to run", the inverter displays alarm code and continues to run at the
frequency set in P9.54. The value in P9.55 is the percentage of the maximum frequency.

In case of a sudden power failure or a sudden drop in voltage, the DC bus voltage is
reduced. This feature allows the inverter to compensate for decreasing the DC bus voltage
by energy of feedback reducing the output frequency to maintain the continuous
operation of the AC motor.
If P9.59 = 1 in case of a sudden power outage or a sudden drop in voltage, the inverter will
decelerate.
After recovering the normal bus voltage, the inverter accelerate to the set frequency. If
the bus voltage remains normal for a time exceeding the value set in P9.61, the bus
voltage is normal.
