15.1.8 Axis swapping
Initially, each channel has some axes assigned to it as set by the
machine parameters. While executing a program, a channel may
release its axes or request new axes. This possibility is determined by
machine parameter
AXISEXCH
, which establishes whether an axis
can change channels or whether this change is permanent or not.
A permanent change is maintained after the end of the program, after
a reset and on power-up. The original configuration may be restored
either by validating the general parameters and restarting or by a part-
program that undoes the changes.
Knowing if an axis can change channels
Machine parameter
AXISEXCH
may be consulted using the following
variable.
V.MPA.AXISEXCH.Xn
Replace "Xn" with the name or logic number of the axis.
Knowing in which channel the axis is
It is possible to know in which channel the axis is by using the following
variable.
V.[n].A.ACTCH.Xn
Replace "Xn" with the name or logic number of the axis.
Replace the "n" letter with the channel number.
Commands for modifying the axis configuration via program
The following instructions are used to modify the configuration of the
axes. It is possible to add or remove axes, change their names and
even redefine the main axes of the channel by swapping their names.
Changing the configuration of the axes cancels the active polar origin,
the pattern rotation, the mirror image and the scaling factor.
In the configuration of the axes (if G17 is active), the axis that occupies
the first position must be the abscissa axis, the second will be the
ordinate axis, the third will be the axis perpendicular to the work plane,
the forth will be the first auxiliary axis and so on.
It also restore the machine parameter settings if a checksum error
occurs when powering up the CNC. .
