Note
Avoidance of multiple selection for FXS
To avoid a multiple selection, we recommend that prior to activating FXS, query either the
$AA_FXS==0 system variable or a user-specific flag. See above, program example N10
Example 2: Traveling to fixed stop with block-related synchronized actions
"Travel to fixed stop" is activated from a specific position of the traversing motion of the
following block
Program code
N10 G0 G90 X0
N20 WHEN $AA_IW[X]>17 DO FXS[X]=1
N30 G1 F200 X100
Note
A block-related synchronized action is processed in the following main program block.
