8.4.3.11 Measurement of a 1-, 2- and 3-dimensional setpoint selection (measurement type 19, 20, 21)
1-dimensional setpoint value ($AC_MEAS_TYPE = 19)
With this measurement method, it is possible to define exactly one setpoint for the abscissa,
the ordinate and the applicate. If two or three setpoints are defined, only the first is accepted
in the sequence abscissa, ordinate and applicate. The tool is not taken into account.
It is purely an actual value memory preset for the abscissa, the ordinate or the applicate.
The values of the following variables are evaluated for measurement type 19:
Input variable
$AC_MEAS_VALID
$AA_MEAS_POINT1[axis]
$AA_MEAS_POINT1[axis]
$AA_MEAS_POINT1[axis]
$AA_MEAS_SETPOINT[axis]
$AC_MEAS_ACT_PLANE
$AC_MEAS_FRAME_SELECT
$AC_MEAS_FINE_TRANS
$AC_MEAS_TYPE
