Detailed description
2.1 Axes
Note
Leading zeroes in user-defined axis identifiers are ignored.
Example:
MD10000 `$MN_AXCONF_MACHAX_NAME_TAB[0] = X01 corresponds to X1
The geometry axes must be assigned to the channel axes in ascending order leaving no
gaps.
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 or link axis) need not be assigned to every channel axis according to:
MD20080 $MC_AXCONF_CHANAX_NAME_TAB (channel axis name in the channel)
through:
MD20070 $MC_AXCONF_MACHAX_USED (machine axis number valid in channel)
.
If the existing concrete machine has a machine axis, which has been specifically assigned to
a certain channel axis, then references to the logical machine axis image:
MD10002 $MN_AXCONF_LOGIC_MACHAX_TAB(logical NCK machine axis image)
are entered in the machine data:
MD20070 $MC_AXCONF_MACHAX_USED (machine axis number valid in the channel)
, 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
