dependent on
inverter model
F23.00 defines the carrier frequency of PWM output wave.
Inverter power Setting range Factory setting
0.2－22kW 1k－16kHz 8kHz
30kW－45kW 1k－12kHz 6kHz
45kW 1k－6kHz 4kHz
55kW and above 1k－4kHz 2kHz
• The carrier frequency will affect the operating noise of the motor. The higher the carrier frequency,
the lower the noise made by the motor. Please properly set the carrier frequency.
• When the value is higher than the factory setting, the inverter should be derated by 5% when per
1kHz is increased compared to the factory setting.
