If the load drop protection function is active, when the inverter output current is less
than the load drop detection level (F8.31)and the duration is longer than the load drop
detection time(F8.32), the inverter output frequency is automatically reduced to 7% of the
rated frequency. During the load drop protection, if the load recovers, the inverter
automatically resumes to the set frequency to run.

action way.
When the motor temperature exceeds motor overheating if forecasting warning
threshold F8.35 ,inverter multifunction DO early warning ON signal output motor
overheating. The motor temperature in d0.41 display.
