Move the principal axis and the parallel axis simultaneously
If the PARAXMODE function is active, the TNC uses the axes defined
in the function to execute the programmed traverse movements.
If the TNC is to traverse 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.
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 "actual value", this movement
will not be shown. If necessary, switch the position
display to "REF value".
