 From the table, we see that the PWM carrier frequency has a significant influence on the

electromagnetic noise, AC motor drive heat dissipation, and motor acoustic noise. Therefore, if the

surrounding noise is greater than the motor noise, lower the carrier frequency is good to reduce the

temperature rise. Although it is quiet operation in the higher carrier frequency, the entire wiring and

interference resistance should be considerate.

 When the carrier frequency is higher than the factory setting, it needs to protect by decreasing the

carrier frequency. See Pr.06-55 for the related setting and details.
