Carrier Frequency
You can change the PWM waveform carrier frequency output from the Inverter.
•With the carrier frequency set high, you can reduce metallic noise from the motor. However, this
may increase electrical noise or leakage current from the Inverter.
•Carrier frequency adjustment also helps avoid mechanical or motor resonance.
•To raise the carrier frequency, reduce the output current (or derate the rated current) as shown in
the graph below.
