Parameters
Parameter Data type Description
RTP REAL Retraction plane (absolute)
RFP REAL Reference plane (absolute)
SDIS REAL Safety clearance (enter without sign)
DP REAL Final drilling depth (absolute)
DPR REAL Final drilling depth relative to the reference plane (enter without
sign)
DTB REAL Dwell time at thread depth (chip breakage)
SDAC INT Direction of rotation after end of cycle
Values: 3, 4 or 5 (for M3, M4 or M5)
MPIT REAL Thread lead as a thread size (signed):
Range of values 3 (for M3) to 48 (for M48); the sign determines
the direction of rotation in the thread
PIT REAL Thread lead as a value (signed)
Range of values: 0.001 ... 2000.000 mm); the sign determines
the direction of rotation in the thread
POSS REAL Spindle position for oriented spindle stop in the cycle (in
degrees)
SST REAL Speed for tapping
SST1 REAL Speed for retraction
Tool axis AXN INT
Values: 1: 1st geometrical axis
2: 2nd geometrical axis
3: 3rd geometrical axis
PSYS INT Internal parameter; only the default value 0 is possible
PSYS INT Internal parameter; only the default value 0 is possible
Machining type VARI INT
Values: 0: Tapping in one pass
1: Deep-hole tapping with chip breakage
2: Deep-hole tapping with chip removal
DAM REAL Incremental drilling depth
value range: 0 <= Max. value
VRT REAL Variable retraction value for chip breakage
value range: 0 <= Max. value
