Parameters
5.210.1 Selection of the characteristic
The part of the characteristic that depends on the diameter can be generated for a linear course of
the tensile force, a linear course of the torque, or on the basis of a specified characteristic. The cor-
responding selection is carried out via the input dwSelectCurve.
5.210.1.1 Characteristic for a linear course of the tensile force
[5-158] Characteristic for a linear course of the tensile force (dwSelectCurve = 0)
•Via dnD0_n you define the diameter at which the reduction of the tensile force is to start.
