Description

Carrier Freq
Adjusts 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 carrier frequency refers to 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
