Du/dt filtering suppresses inverter output voltage spikes and rapid voltage changes that stress motor insulation. the motor does not fulfil the following requirements, the lifetime the motor might shorten.e.3. As with all frequency converters employing the most modern IGBT inverter technology, the ACS800 output comprises regardless output frequency pulses of approximately 1. 500 600 Standard insulation system conjunction with du/dt filtering reinforced insulation.
