This function is used to adjust the carrier wave frequency of the inverter. By
adjusting the carrier wave frequency, the motor noise can be reduced, the
resonance of the mechanical system can be avoided, so that the leakage
current to the ground and the interference of the inverter can be reduced.
When the carrier wave frequency is low, the output current higher harmonic
component will be increased, the motor loss will be increased, and the
motor temperature rise will also increase.
When the carrier wave frequency is high, the motor loss is reduced, and
the motor temperature is reduced also, but the inverter loss and inverter
temperature rise will be increased, and thus the interference will be
increased.
The adjustment of carrier frequency will have the following influences on
the performance:
