Detailed description
2.7 Actions in synchronized actions
Dimensions: Absolute/incremental
The commands
programmed in synchronized actions. Therefore by default, the dimensions that were active
in the part program at the time of execution of the synchronized action is also effective in the
synchronized action.
The following commands can be programmed in the action part to specify the dimensions
within a synchronized action:
Command
IC(...)
AC(...)
DC(...)
ACN(...)
ACP(...)
CAC(...)
CIC(...)
CDC(...)
CACN(...)
CACP(...)
Examples:
Program code
; Incremental traversing by 10 mm
ID=1 EVERY G710 $AA_IM[B]>75 DO POS[X]=IC(10)
...
; Absolute traversing
ID=1 EVERY G710 $AA_IM[B]>75 DO POS[X]=AC($AA_MW[V]-$AA_IM[W]+13.5)
Behavior with active axial frames
If programmable and settable frames and tool length compensations are not explicitly
deactivated for inclusion in the calculation for synchronized actions via the following machine
data, the frame and/or tool length compensation active in the part program at the time the
synchronized action is executed in parallel, takes effect:
MD32074 $MA_FRAME_OR_CORRPOS_NOTALLOWED, bit 9 = 1

G90 G91
Meaning
Incremental
Absolute
Direct, i.e. position rotary axis via shortest route
Position modulo rotary axis absolutely in negative direction of motion
Position modulo rotary axis absolutely in positive direction of motion
Traverse axis to coded position absolutely
Traverse axis to coded position incrementally
Traverse rotary axis to coded position via shortest route
Traverse modulo rotary axis to coded position in negative direction
Traverse modulo rotary axis to coded position in positive direction
