Description
Cn.04 Carrier
Freq
Adjust motor operational noise by changing carrier frequency settings.
Power transistors (IGBT) in the inverter generate and supply high
frequency switching voltage to the motor. The switching speed in this
process refers to the carrier frequency. If the carrier frequency is set
high, it reduces operational noise from the motor, and if the carrier
frequency is set low, it increases operational noise from the motor.
