Parameter Description
V2 Retraction distance after each machining step – (for chip breaking only).
Distance by which the drill is retracted for chip breaking.
V2 = 0: The tool is not retracted but is left in place for one revolution.

● Automatic
The clearance distance is calculated by the cycle.
V3 Clearance distance – (for swarf removal only and manual limit distance)
Distance to the last infeed depth that the drill approaches in rapid traverse after swarf
removal.

Note:
DT > 0: The programmed value is effective
DT = 0: The same value is effective as programmed under DTB (DT = DTB)
