Note
If an axis is situated between two positions, it does not traverse in response to an
incremental position command with CIC (...). It is always advisable to program the first travel
command with an absolute position value.
Example 2
N10 FA[B]= 300 ;Feed for positioning axis B
N20 POS[B]= CAC (10) ;Approach coded position 10 (absolutely)
N30 POS[B]= CIC (-4) ;Travel 4 spaces back from the current position
