In the no-load or light load process of the motor, detect the load current and properly adjust output
voltage to achieve energy-saving effect.
 Note
This function is especially suitable for the fan and pump load.

 Note
1. The carrier wave frequency can affect noise during the motor running, generally, it can be set as 3~5kHz.
For the occasion when the quiet running is required, the carrier wave frequency can be generally set as
6~8kHz.
2. When the drive is running with the carrier wave frequency above the leave-factory setting value, the drive
needs to derate 5% of the power to run for every increase of 1kHz.
3. In the vector control mode, the minimum for the setting range of the carrier wave frequency is 2kHz.
