6.2.16 F18: PWM Parameters
Ref. Code Function Description Setting Range [Default]
F18.00 Carrier frequency 1 - 16kHz [Depend on HD3L]
Defines the carrier frequency of PWM output wave.
Controller power Setting range Factory setting
2.2 - 22kW 1 - 16kHz 8kHz
30 - 45kW 1 - 12kHz 6kHz
• 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, HD3L should be derated by 5% when per 1kHz is
increased compared to the factory setting.
