Figure 2-24 NCU2 to NCUn use a lead link axis to enable coupling to the machine axis on NCU1 (NCU1-AX3).
The following example refers to the axis coupling section between Y(LAX2, AX2) as
following axis on NCU2 and Z(LAX3, NC1_AX3) as lead link axis.
Machine data
● The machine data of a leading value axis may only be loaded on the home NCU. From
this NCU, the relevant machine data are distributed to the other NCUs where a lead link
axis has been defined.
● Each lead link axis reduces the maximum number of axes that can be traversed on this
NCU by one axis.
