FUNCTION PARAXMODE
Example
13 FUNCTION PARAXMODE X Y W
To activate the
PARAXMODE
function, you must always
define three axes.
If you combine the
PARAXMODE
and
PARAXCOMP
functions, the control will deactivate the
PARAXCOMP
function for an axis that was defined in both functions.
Once you deactivate
PARAXMODE
, the
PARAXCOMP
function becomes active again.
Use the
PARAXMODE
function to define the axes the control is
to use for machining. You program all traverse movements and
contour descriptions in the principal axes X, Y and Z, independent
of your machine.
Define 3 axes in the
PARAXMODE
function (e.g.
FUNCTION
PARAXMODE X Y W
) to be used by the control for programmed
traverse movements.
Proceed as follows for the definition:
Show the soft-key row with special functions
Press the
PROGRAM FUNCTIONS
soft key
Select
FUNCTION PARAX
Select
FUNCTION PARAXMODE
Select
FUNCTION PARAXMODE
Define the axes for machining
Move the principal axis and the parallel axis simultaneously
Example
13 FUNCTION PARAXMODE X Y W
14 L Z+100 &Z+150 R0 FMAX
If the
PARAXMODE
function is active, the control uses the axes
defined in the function to execute the programmed traverse
movements. If the control is to move a parallel axis simultaneously
with the associated principal axis, you can identify the respective
axis by additionally entering the
& character. The axis with the &
character then refers to the principal axis.
