Data type Meaning
1 RP <RTP> REAL Retraction plane (abs)
2 Z0 <RFP> REAL Reference point (abs)
3 SC <SDIS> REAL Safety clearance (to be added to reference point, enter without sign)
4 Z1 <DP> REAL Drilling depth (abs), see <_AMODE>
5 Z1 <DPR> REAL Drilling depth (inc), see <_AMODE>
6 DT <DTB> REAL Dwell time in seconds at drilling depth / safety clearance after retraction,
see <ENC>
7 <SDR> INT Direction of rotation for retraction
8 SDE <SDAC> INT Direction of rotation after end of cycle
9 <ENC> INT Tapping with spindle mounted encoder (G33)/tapping without spindle
mounted encoder (G63)
0 = With spindle moun‐
ted encoder
- Pitch
from <MPIT>/
<PIT> - without
DT
20 = With spindle moun‐
ted encoder
- Pitch from
<MPIT>/<PIT> -
with DT after retrac‐
tion to safety clear‐
ance
11 = Without spindle
mounted encoder
- Pitch
from <MPIT>/
<PIT> - with DT
at drilling depth
1 = Without spindle
mounted encoder
- Pitch from pro‐
grammed feedrate
- with DT at drilling
depth (feedrate =
speed · pitch)
10 <MPIT> REAL Thread size for "ISO metric" only (pitch is calculated internally during run
time)
Range of values: 3 to 48 (for M3 to M48), alternative to <PIT>
11 <PIT> REAL Pitch as a value, for unit see <_PITA>
Range of values: > 0, alternative to MPIT
12 <_AXN> INT Drilling axis 0 = 3rd geometry axis
1 = 1st geometry axis
2 = 2nd geometry axis
≥ 3 = 3rd geometry axis
