Data type Meaning
1 RP <_RTP> REAL Retraction plane (abs)
2 Z0 <_RFP> REAL Reference point of tool axis (abs)
3 SC <_SDIS> REAL Safety clearance (to be added to reference point, enter without sign)
4 Z1 <_DP> REAL Final drilling depth (abs/inc), see <_AMODE>
5 <_ADPR> REAL Predrilling depth with reduced drilling feedrate (inc) effective
with <_VARI> TEN THOUSANDS
6 D <_FDPR> REAL Maximum depth infeed (inc)
D ≥ Z1 ⇒ One infeed to the final drilling depth
D < Z1 ⇒ Deep drilling cycle with multiple infeeds and chip removal
7 ZR <_LDPR> REAL Remaining drilling depth when through-drilling (inc) with FR feed
8 <_DIAM> REAL Nominal diameter of the thread
9 P <_PIT> REAL Pitch as a numerical value
10 <_PITA> INT Evaluation of thread pitch P
1 = Pitch in mm/rev
2 = Pitch in threads/inch
3 = Pitch in inch/rev
4 = Pitch as MODULE
11 DF <_DAM> REAL Absolute value / percentage for each additional infeed (degression),
see<_AMODE>
12 V1 <_MDEP> REAL Minimum infeed (inc), only active for degression
