2-dimensional setpoint selection
Program code Comment
DEF INT RETVAL
DEF REAL _CORMW_XX,
_CORMW_YY,
_CORMW_ZZ
DEF AXIS _XX, _YY, _ZZ
T1 D1 ; Activate probe
G54 ; Activate all frames and G54
$AC_MEAS_VALID = 0 ; Set all input values to invalid
$AC_MEAS_TYPE = 20 ; Set measurement type for 2-dimensional
setpoint selection
$AC_MEAS_ACT_PLANE = 0 ; Measuring plane is G17
_XX=$P_AXN1 ; Define axes according to the plane
_YY=$P_AXN2
_ZZ=$P_AXN3
; Assign measured values
$AA_MEAS_POINT1[_xx] = $AA_MW[_xx] ; Assign measurement value to abscissa
$AA_MEAS_POINT1[_yy] = $AA_MW[_yy] ; Assign measurement value to ordinate
$AA_MEAS_POINT1[_zz] = $AA_MW[_zz] ; Assign measurement value to applicate
$AA_MEAS_SETPOINT[_xx] = 10 ; Define setpoint for abscissa and ordinate
$AA_MEAS_SETPOINT[_yy] = 10
$AC_MEAS_FRAME_SELECT = 102 ; Select target frame - G55
RETVAL = MEASURE() ; Start measurement calculation
if RETVAL <> 0
setal(61000 + RETVAL)
endif
$P_UIFR[2] = $AC_MEAS_FRAME ; Write measurement frame in data management
(G55)
G55 G0 AX[_xx]=10 AX[_yy]=10 ; Activate frame and traverse
