Data type Meaning
101 ZO calculation in hole with ZO compensation
102 ZO calculation on shaft with ZO compensation
103 ZO calculation in groove with ZO compensation
104 ZO calculation on web with ZO compensation
REAL, >0 Setpoint diameter, width (acc. to drawing)
REAL Center point of abscissa
(with reference to workpiece zero)
REAL Center point of ordinate
(with reference to workpiece zero)
-360 to Start angle
+360
degrees
REAL Incremental lifting of applicate with prefix
(only measure with web, lift for crossing)
-360 to Indexing angle (only for measuring hole or shaft)
+360 useful values for 3-point measurement: -120 ... + 120 degrees
degrees useful values for four-point measurement: -90 ... +90 degrees
REAL, >0 Feed for circular interpolation (mm/min)
(only measure for hole and/or shaft)
0, >0 0: without automatic ZO correction
>0: with automatic ZO correction
