Siemens SINUMERIK 840D sl Operating Manual page 269

If 3 or 6 positions are not sufficient for the approach/retraction, you can call the cycle several
times in succession to program further positions.
Risk of collision
Note that the tool will move from the last position programmed in the approach/retraction
cycle directly to the starting point for the next machining operation.
