Droop control
This is a function to give droop characteristics to the speed by balancing the load in proportion with the load torque
during the Advanced magnetic flux vector control, Real sensorless vector control, vector control, and PM sensorless
vector control.
This is effective when balancing the load when using multiple inverters.
