Moving the principal axis and the parallel axis
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 the principal axis deselected by
PARAXMODE, you can identify this axis by additionally entering the
character &. The & character then refers to the principal axis.
Proceed as follows:
Press the L key
The control opens a linear block.
Define coordinates
Define radius compensation
Press the left arrow key
The control shows the & character.
If applicable, use the axis-direction keys to select
the axis
Define coordinate
Press the ENT key
Example
13 FUNCTION PARAXMODE X Y W
14 L Z+100 &Z+150 R0 FMAX
The & syntax element is only permitted in L blocks.
Additional positioning of a principal axis with the &
command is done in the REF system. If you have set
the position display to display ACTUAL values, this
movement will not be shown. If necessary, switch the
position display to REF values.
Your machine tool builder will define the calculation of
possible offset values (X_OFFS, Y_OFFS and Z_OFFS
from the preset table) for the axes positioned with the &
operator in the presetToAlignAxis machine parameter
(no. 300203).
