7.16 F23: PWM Controlling Parameter
Ref. Code Function Description Setting Range [Default]
F23.00 Carrier frequency setting 1 - 16 [4kHz]
Define carrier frequency of converter output PWM wave.
• Carrier frequency will affect motor running noise. Higher the carrier frequency, less noise. Please set it
reasonably.
• If F23.00 > 4kHz, each1kHz added, converter should be derated by 5%.
