TENSION SENSORLESS TORQUE CONTROL
5.5.4
Taper function
The taper function reduces the tension when the winding diameter increases in order to prevent the roll from getting too tight.
From a tension value commanded for taper control and the roll diameter determined by the winding diameter calculation, a
torque command value required for the tension control is calculated.
