2.6 Link axes
This method of programming is permitted only if machine axis AX3 is known in the channel
at the time of scanning.
Note
System variables which can be used in conjunction with channel axis identifiers are specially
marked in the Job Planning Programming Manual (Appendix).

Flexible configuration

Introduction
Rotary indexing machines and multi-spindle machines have special requirements as regards
the flexible assignment of channel axes to machine axes.
Requirement profile
When advancing the table of the rotary indexing machine or the drum of the multi-spindle
machines, the axes/spindles are brought to a new station or position. The NCU which
controls the axes of a station as local axes must be able to address the newly changed
axes/spindles. The hitherto addressable axes/spindles can now be discarded for this
purpose.
Solution
A configuration of the relevant axes in an axis container specified in machine data enables
different machine axes to be located in succession behind a channel axis that remains
constant. Advancing the rotary table or drum is performed synchronously with the advancing
of the axes entered in the axis container.
Axes in an axis container can also be configured as geometry axes.
Note
The axis container has no mode group reference,
i.e. the workpiece-holding, traveling axis can change from one mode group to another at
different machining stations.
