7.5.3.11 Measurement of a 1-, 2- and 3-dimensional setpoint selection (measurement type 19,
20, 21)
1-di
mensional 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 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 of abscissa or ordinate or applicate
$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 19
* optional
The following output variables are written for measurement type 19:
Output variable Meaning
$AC_MEAS_FRAME Result frame with rotations and translation
Example
1-dimensional setpoint selection
