Coupling module

With the aid of a coupling module, the motion of one axis, (→ following axis), can be interpolated
depending on other (→ leading) axes.
Coupling rule
The relationships between leading axis/values and a following axis are defined by a coupling
rule (coupling factor or curve table). The individual motion components from the individual
leading axes/values have an additive effect.
The relationship is demonstrated by the following example (following axis with two leading
axes):
