Traversing command axes (POS)

Axes can be traversed as command axes via synchronized actions with the
Alternate traversing of the axis via the part program and the synchronized action is thus
possible. If a command axis traversed via synchronized actions is subsequently traversed
via the part program, a preprocessing stop with reorganization (
channel of the part program.
Examples:
Example 1: Alternate traversing via part program and synchronized action
Program code
N10 G01 X100 Y200 F1000
...
; Traversing via static synchronized action when input 1 is set
N20 ID=1 WHEN $A_IN[1]==1 DO POS[X]=150 FA[X]=200
...
CANCEL(1)
...
; Traversing again via part program => implicit preprocessing stop
; with reorganization, if the X axis in the meantime has been
; traversed via synchronized action
N100 G01 X240 Y200 F1000
Example 2: Alternate traversing of the X-axis via two synchronized actions
If the traversing motion of one synchronized action is still active when the traversing motion
of the other synchronized action is started, the second traversing motion replaces the first.
Program code
; 1st traversing motion
ID=1 EVERY $A_IN[1]>=1 DO POS[V]=100 FA[V]=560
; 2nd traversing motion
ID=2 EVERY $A_IN[2]>=1 DO POS[V]=$AA_IM[V] FA[V]=790
