The values of the following variables are evaluated for measurement type 16:
Input variable Meaning
$AC_MEAS_VALID Validity bits for input variables
$AA_MEAS_POINT1[axis] Measuring point 1
$AA_MEAS_POINT2[axis] Measuring point 2
$AA_MEAS_SETANGLE Setpoint angle *
$AC_MEAS_ACT_PLANE Calculated as active plane unless otherwise specified *
$AC_MEAS_FINE_TRANS 0: Coarse offset, 1: Fine offset *
$AC_MEAS_FRAME_SELECT Calculated as additive frame unless otherwise specified *
$AC_MEAS_T_NUMBER Calculated as active T unless otherwise specified (T0) *
$AC_MEAS_D_NUMBER Calculated as active D unless otherwise specified (D0) *
$AC_MEAS_INPUT[0] Unless otherwise specified, the reference coordinate for the
alignment of the workpiece is always the abscissa of the
selected plane. *
=0: Reference coordinate is the abscissa
=1: Reference coordinate is the ordinate
$AC_MEAS_INPUT[1] Unless otherwise specified, the workpiece position angle is
entered in the frame as a rotation. Otherwise, a channel axis
index can be specified for a rotary axis whose translation is set
to the current rotary axis position plus the calculated rotation.
The workpiece is then aligned at rotary axis position = 0. The
current rotary axis value must be set in
$AA_MEAS_POINT[axis]. *
$AC_MEAS_TYPE 16
* optional
The following output variables are written for measurement type 16:
Output variable Meaning
$AC_MEAS_FRAME Result frame with rotation
$AC_MEAS_WP_ANGLE Calculated workpiece position angle
