Example of an axis replacement

Assumption
With 6 axes and 2 channels, the 1st, 2nd, 3rd and 4th axis in channel 1 and the 5th and 6th
axis in channel 2 shall be used. It shall be possible to replace the 2nd axis between the
channels and to allocate to channel 1 after power ON.
Exercise
The task is subdivided into the following areas:
● Machine data allocation so that the prerequisites for axis replacement are given.
● Programming of axis replacement between channel 1 and channel 2.
