5.16.15 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, vec-
tor control, and PM sensorless vector control.
This is effective when balancing the load when using multiple inverters.
