2-dimensional setpoint value ($AC_MEAS_TYPE = 20)
Setpoints for two dimensions can be defined using this measuring method. Any combination
of 2 out of 3 axes is permissible. If three setpoints are specified, only the values for the
abscissa and the ordinate are accepted. The tool is not taken into account.
This is a purely actual value memory preset.
The values of the following variables are evaluated for measurement type 20:
Input variable Meaning
$AC_MEAS_VALID Validity bits for input variables
$AA_MEAS_POINT1[axis] Measuring point 1 for the abscissa
$AA_MEAS_POINT1[axis] Measuring point 1 for the ordinate
$AA_MEAS_POINT1[axis] Measuring point 1 for the applicate
$AA_MEAS_SETPOINT[axis] Setpoint position for the 1st dimension
$AA_MEAS_SETPOINT[axis] Setpoint position for the 2nd dimension
$AC_MEAS_ACT_PLANE Calculated as active plane unless otherwise specified *
$AC_MEAS_FRAME_SELECT Calculated as additive frame unless otherwise specified *
$AC_MEAS_FINE_TRANS Unless otherwise specified, frame is written to coarse translation
*
$AC_MEAS_TYPE 20
* optional
