This parameter determines the PWM carrier frequency of the GS4 drive.
• When carrier frequency is higher than the factory setting, reference parameter P6�33 Drive
Derating Method for frequency derating of the GS4 drive�
• When P6�34 (VT/CT Duty Selection) is set, it can change this parameter (P2�10)�
• P6�00/P6�02 (Electronic Thermal O/L Relay) must be set independently�
As shown in the diagram below, the PWM carrier frequency has a significant influence on
electromagnetic noise, GS4 drive heat dissipation, and motor acoustic noise. Therefore, if
surrounding ambient noise is greater than motor noise, then lowering the carrier frequency will
help to reduce temperature rise in the motor. Although motor noise is reduced at the higher
carrier frequencies, the entire wiring and interference resistance should be considered before
choosing a higher frequency.
