Data type Meaning
INT Evaluation of thread pitch
STRING[15] String as marker for pitch input (for the interface only)
STRING[20] String for thread table ("", "ISO", "BSW", "BSP", "UNC") (for the interface
only)
STRING[20] String for selection from thread table (e.g. "M 10", "M 12", ...) (for the
interface only)
INT Geometrical mode (evaluation of programmed geometrical data)
UNITS:
TENS:
HUNDREDS:
INT Display mode
UNITS:
INT Alternative mode
UNITS:
0 = Compatibility mode
1 = Pitch in mm
2 = Pitch in threads per inch (TPI)
3 = Pitch in inches
4 = Pitch as MODULE
Reserved

Machining/calculation of start point
0 = Compatibility mode
1 = Normal machining
Machining plane G17/G18/G19
0 = Compatibility, the plane effective
before the cycle call remains ac‐
tive
1 = G17 (only active in the cycle)
2 = G18 (only active in the cycle)
3 = G19 (only active in the cycle)
Thread length (<_DP>)
0 = Absolute
1 = Incremental
