Examples
Program code Comment
POS[B]=CAC(20) ; Indexing axis B approaches the coded position (indexing)
20 in absolute mode. The direction of traversing depends
on the current actual position.
Program code Comment
POS[B]=CACP(10) ; Indexing axis B approaches the coded position (index
position ) 10 in absolute mode with positive direction of
rotation (possible only for rotary axes).
Program code Comment
POS[B]=CACN(10) ; Indexing axis B approaches the coded position (index
position ) 10 in absolute mode with negative direction of
rotation (possible only for rotary axes).
Program code Comment
POS[B]=CDC(50) ; Indexing axis B approaches indexing position 50 directly
along the shortest path (possible only for rotary axes).
Program code Comment
POS[B]=CIC(-4) ; Indexing axis B traverses four indexing positions
incrementally from its current position. in a negative
direction.
Program code Comment
POS[B]=CIC(35) ; Indexing axis B traverses 35 indexing positions
incrementally from its present position in a positive
direction.
Special features
● Modulo rotary axis as indexing axis
On modulo rotary axes, the indexing positions are divided in factors of 360° and
approached directly.
● Indexing axis is between two indexing positions
The specified position instructions have the following effect in the AUTOMATIC mode.
POS[B]=CIC(1)
The next higher indexing position is approached.
POS[B]=CIC(-1)
The next lower indexing position is approached.
POS[B]=CIC(0)
The indexing axis is not traversed.
