5.210.1.2 Characteristic for a linear course of the torque
[5-159] Characteristic for a linear course of the torque (dwSelectCurve = 1)
•Via dnD0_n you define the diameter at which the reduction of the tensile force is to start.
• Since this characteristic selection focuses on the linear course of the torque, in this case you de-
fine the steepness of the torque curve via dnCurveCtrl_n:
•At dnCurveCtrl_n = 100 % the tensile force remains unchanged.
•At dnCurveCtrl_n = 0 % the tensile force is reduced to D0/DMax.
