Adjust motor operational noise by changing the carrier frequency settings. Power transistors (IGBT)
in the Inverter generate and supply high frequency switching voltage to the motor. Carrier
frequency is the switching speed in this process. If the carrier frequency is set high, it reduces
operational noise from the motor. If the carrier frequency is set low, it increases operational noise
from the motor.
Below demonstrates the advantages and disadvantages according to the sound of the Inverter
during operation.
