Configuration

Figure 2-52 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.
Loading the machine data
1. The machine data/setting data of a master value axis may only be loaded on the home
NCU. The machine data are distributed internally to the other NCUs where a lead link
axis has been defined.
2. The lead link axis must be taken into account when configuring the NCU that is traversing
the following axes (NCU2). The lead link axis occupies one location in the logical machine
axis image (LAI) of the (NCU2). This reduces the maximum number of axes to be
interpolated by this NCU by 1 for the lead link axis.
250
In addition to the LAI axis location definition, the lead link axis must also be defined as
channel axis ($MC_AXCONF_MACHAX_USED) in every channel where it will be used
together with the following axis; this also reduces the maximum number of possible
channel axes.
