F23.00 defines the carrier frequency of PWM output wave.
• 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.
