output frequency due to the load inertia. At this time, the motor will feed the energy back
to the inverter, resulting in DC bus voltage rise. If no measures taken, the inverter will trip
due to over voltage.
During deceleration, the inverter detects DC bus voltage and compares it with
over-voltage stall protection point. If DC bus voltage exceeds PB.10, the inverter will stop
reducing its output frequency. When DC bus voltage become lower than PB.10, the
deceleration continues, as shown in following figure.
