2.11 Lead link axis
● The lead link axis must be configured in the logical machine axis image with machine
● The lead link axis must also be configured in the channel axes.
Note
For further information about link-specific machine data, please refer to the preceding
subsections and the configuration and programming example provided in Section
"Examples".
Schematic sequence
The diagram below shows the constellation used in the example with the main data flows.
NCU 1 provides:
Interpolation and position control for master value axis or supplies the lead link axis of NCU2
with setpoint and actual value.
NCU 2 provides:
Coupling between lead link axis and master value axis (of NCU1) and generation of a
dependent axis motion (following axis).

This allows a relation to be established with the NCU that is interpolating the lead link
axis.
