Function description
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.

When droop is active, the ramp-function generators of all of the coupled drives must be set to
have identical ramp-up and ramp-down times as well as rounding-off.
After selecting application class "Dynamic Drive Control", droop is no longer possible.
