A: The carrier frequency is an important parameter for the VFD operation. If increase it, the output waveform will be better and the electromagnetic noise will be smaller, but it will increase the inverter's operating temperature, poor heat dissipation, and greater leakage current. The factory default parameters have been reasonably set, and adjustments are not recommended. If it is adjusted larger, the inverter needs to be derated for use. For every additional 1k, derate by 10%.
