Reliability of channel axis gaps
Channel axis gaps must be communicated explicitly through the following machine data:
MD11640 $MN_ENABLE_CHAN_AX_GAP (channel axis gaps are allowed in
AXCONF_MACHAX_USED)
If this is not carried out, an entry of 0 prevents other machine axes being assigned to
channel axes in the following machine data:
MD20070 $MC_AXCONF_MACHAX_USED (machine axis number valid in channel)

Decentralized Systems (B3)
Example
In the example below, a machine tool channel axis is specified without a real machine axis.
