4.5.2 MK_APPLACHSIDX
This MC has 18 parameters, one for each of the 18 possible axis letters. The
order of the letters assigned to the parameters is fixed. Only the assignment
of the application axis numbers can be freely selected. The order of the
letters is as follows
X Y Z C U V W A B u v w a b c x y z
Exactly one application axis can be assigned to each letter. For the letters
that are not used, enter −1 or any non−configured application axis number.
The control only searches the axes that are configured in MK_CANDRIVES
and assigns the first axis letters it finds to the axes. Therefore, if you specify
one application axis number more than once in this MC, the first letter is
used and the others are ignored.
The assignment of axis letter is completely optional. However, you should
observe the following rules which make it easier for others to understand
your machine.
Identify the linear principle axes of the machine with X, Y, Z and the rotative
principle axes with A, B, C. Define X, Y, Z in such a way that you specify a
clockwise workpiece coordinate system and that the rotation axis A rotates
around the X, rotation axis B around the Y and C around the Z axis. The axes
U, V, W should be used for linear auxiliary axes with U moving parallel to X,
V parallel to Y and W parallel to Z.
In MK_APPLACHSIDX the application−related order of axis letters is defined
by means of numerical assignment. This order of axes is valid for all
axis−related machine constants!
