Droop
For mechanically coupled drives, there is the risk that the drives oppose one another: Small
deviations in the speed setpoint or actual value of the coupled drives can mean that the
drives are operated with significantly different torques.
The droop function ensures even torque distribution between several mechanically coupled
drives.
The droop function reduces the speed setpoint as a function of the torque setpoint.
