Detailed description
2.4 Actions in synchronized actions
Examples:
ID=1 EVERY $AC_TIMER[1] >= 5 DO POS[V]=100 FA[V]=560
ID=2 EVERY $AC_TIMER[1] >= 7 DO POS[V]=$AA_IM[V] + 2 FA[V]=790
; Owing to the programming with $AC_TIMER[1] the synchronization with ID=2 is the most
recently activated, its specifications become effective and release the specifications of ID=1
... .
The end position and feedrate for a command axis can therefore be adjusted while the axis
is in motion.
Example Activation by signal
ID=1 EVERY $A_IN[1]==1 DO POS[U]=$AA_IM[U]+$AA_IM[V]*.5
