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.
