Notice:
1: In the normal V/F control mode, the automatic torque boost mode is invalid.
2: Automatic torque boost is only valid in advanced V/F control mode.

This function code is used to set the carrier frequency of the PWM wave output by the inverter. The carrier frequency will affect the noise when the motor is running.
For occasions that require silent operation, the carrier frequency can be appropriately increased to meet the requirements. However, increasing the carrier frequency
will increase the heat generation of the inverter and at the same time increase the electromagnetic interference to the outside world.
When the carrier frequency exceeds the factory setting value, the inverter needs to be derated for use. Generally, the inverter current needs to be derated by about
5% for every 1KHz increase in the download wave.
