Note
Leading zeroes in user-defined axis identifiers are ignored.
Example:
MD10000 AXCONF_MACHAX_NAME_TAB[0] = X01 is equivalent to X1
The geometry axes must be assigned to the channel axes in ascending order leaving no
gaps.
Special features
• 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
Channel axes need not be defined contiguously in ascending order, in other words, not each
channel axis needs to have a machine axis assigned to it (local or link axis). The assignment
occurs as follows:
• MD20080 AXCONF_CHANAX_NAME_TAB
• MD20070 AXCONF_MACHAX_USED
Application:
Consistent, semidefined channel axes 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
Channel axis gaps must be disconnected via the machine data:
• MD11640 ENABLE_CHAN_AX_GAP = 1 (Channel axis gap allowed).
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.
