Data type Meaning
REAL Retraction plane (abs)
REAL Reference point (abs)
REAL Safety clearance (to be added to reference point, enter without sign)
REAL Drilling depth (abs), see <_AMODE>
REAL Drilling depth (inc), see <_AMODE>
REAL Dwell time in seconds at drilling depth / safety clearance after retraction,
see <ENC>
INT Direction of rotation for retraction
INT Direction of rotation after end of cycle
INT Tapping with spindle mounted encoder (G33)/tapping without spindle
mounted encoder (G63)
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>
REAL Pitch as a value, for unit see <_PITA>
Range of values: > 0, alternative to MPIT
INT Drilling axis
3.25 Programming cycles externally
0 = With spindle moun‐
ted encoder
20 = With spindle moun‐
ted encoder
11 = Without spindle
mounted encoder
1 = Without spindle
mounted encoder
0 = 3rd geometry axis
1 = 1st geometry axis
2 = 2nd geometry axis
≥ 3 = 3rd geometry axis
