3-dimensional setpoint value ($AC_MEAS_TYPE = 21)
Using this measurement method, it is possible to define a setpoint for the abscissa, the
ordinate and the applicate. The tool is not taken into account.
It is purely an actual value memory preset for the abscissa, ordinate and applicate.
The values of the following variables are evaluated for measurement type 21:
Input variable
$AC_MEAS_VALID
$AA_MEAS_POINT1[axis]
$AA_MEAS_POINT1[axis]
$AA_MEAS_POINT1[axis]
$AA_MEAS_SETPOINT[axis]
$AA_MEAS_SETPOINT[axis]
$AA_MEAS_SETPOINT[axis]
$AC_MEAS_ACT_PLANE
$AC_MEAS_FRAME_SELECT
$AC_MEAS_FINE_TRANS
$AC_MEAS_TYPE
* optional
The following output variables are written for measurement type 21:
Output variable
$AC_MEAS_FRAME
