Data type Meaning
105 Set up internal corner of a rectangle
(geometry known, 3 measuring points)
106 Set up external corner of a rectangle
(geometry known, 3 measuring points)
107 Set up internal corner (geometry unknown, 4 measuring points)
108 Set up external corner (geometry unknown, 4 measuring points)
REAL Measuring path, only included if _FA larger than internally calculated
0, >0 0: without automatic ZO correction
>0: with automatic ZO correction
(Individual values: see Parameter description section "Description of
the most important defining parameters"., Parameter _KNUM)
REAL Approx. angle of posit. direction of the abscissa with respect to
reference edge of the workpiece in MCS
Negative value in clockwise direction
•
Positive value in counterclockwise direction
•
REAL Approximate angle between reference edge and 2nd edge of
workpiece (precision: <10 degrees):
Negative value in clockwise direction
•
Positive value in counterclockwise direction
•
REAL Incremental retraction of applicate when measuring external corner,
used to travel around the corner, especially _ID=0: The corner is
traveled around – not passed over.
REAL, >0 Distance between starting point and measuring point 2 in direction
_STA1 (P1 is at _SETV[0] / 2)
REAL, >0 Distance between starting point and measuring point 4 in direction
STA1+ INCA (P3 is at _SETV[1] / 2)
REAL Offset of zero offset WCS (corrected) in abscissa
REAL Offset of zero offset WCS (corrected) in ordinate
REAL Selection of offset:
Values: 1: Measured corner entered as zero point
2: Measured corner is entered as zero point in abscissa
offset by _SETV[2]
3: Measured corner is entered as zero point in both axes
offset by _SETV[2] (abscissa) and _SETV[3] (ordinate) .
4: Measured corner is entered as zero point in ordinate
offset by _SETV[3].
