Examples
Example 1:
Program code
ID=1 EVERY $AA_IM[B]>75 DO POS[U]=100
ID=1 EVERY $AA_IM[B]>75 DO POS[U]=$AA_MW[V]-$AA_IM[W]+13.5
Example 2:
Program environment influences the positioning travel of the positioning axis
(no G function in the action component of the synchronized action):
Program code
N100 R1=0
N110 G0 X0 Z0
N120 WAITP(X)
N130 ID=1 WHENEVER $R==1 DO POS[X]=10
N140 R1=1
N150 G71 Z10 F10
N160 G70 Z10 F10
N170 G71 Z10 F10
N180 M30
G71
of the positioning axis (metric) independent of the program environment:
Program code
N100 R1=0
N110 G0 X0 Z0
N120 WAITP(X)
N130 ID=1 WHENEVER $R==1 DO G71 POS[X]=10
N140 R1=1
N150 G71 Z10 F10
N160 G70 Z10 F10
N170 G71 Z10 F10
N180 M30

in the action component of the synchronized action clearly defines the positioning travel
Comments
; Axis U traverses, dependent on the traversing mode,
incrementally through 100 (inch/mm) or to position
100 (inch/mm) from the control zero.
; Traverse axis U by the distance calculated from the
main run variables:
Comments
; Z=10mm X=10mm
; Z=254mm X=254mm
; Z=10mm X=10mm
Comments
; Z=10mm X=10mm
; Z=254mm X=10mm (X always positions to 10mm)
; Z=10mm X=10mm
