Lead link axes

Following axis movements
The configuration illustrated below shows how to traverse following axes on several NCUs
(NCU2 to NCU n in the diagram) in relation to the movement of the leading axis controlled by
another NCU (NCU 1 in the example).
Figure 2-10 NCU 2 moves the following axes via a coupling to a leading axis on NCU1
If the supplementary conditions described in the "Detailed description" are complied with, it is
possible for several NCUs in the whole NCU link group to traverse leading axes and for other
NCUs to derive following axis movements from them. The leading axes must only be
traversed by the NCUs to which they are physically connected (local NCUs). (Home NCUs).
