 From the table, you see that the PWM carrier frequency has significant influences on the
electromagnetic noise, the AC motor drive heat dissipation, and the 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.
