Special points to be noted
• Three geometry axes are assigned to the channel axes in the MD.
• All channel axes that are not assigned to the three geometry axes are special axes.
• The channel axes are assigned to machine axes.
• The spindles are also assigned to machine axes.
Channel axis gaps
A machine axis (local axis or link axis) does not have to be assigned to every channel axis
according to
MD20080 AXCONF_CHANAX_NAME_TAB
via
MD20070 AXCONF_MACHAX_USED.
If the concrete machine has a machine axis, which has been specifically assigned to the
channel axis, references to the logical machine axis image
MD10002 AXCONF_LOGIC_MACHAX_TAB
are entered in the machine data
MD20070 AXCONF_MACHAX_USED,
otherwise the value is 0.
Application:
Consistent, semidefined channel axis names for various machine versions of a
manufacturer's machine series.
Advantages:
• Uniform basic configuration of various machines
• Simple reconfiguration on removal of a machine
• Portability of programs
Reliability of channel axis gaps
The machine data
MD11640 ENABLE_CHAN_AX_GAP
must be used to explicitly inform of channel axis gaps.
If this is not carried out, an entry of 0 in the machine data
MD20070 AXCONF_MACHAX_USED
prevents other machine axes being assigned to channel axes.
