MEAW=1 G1 X... Y... Z... F... ; Measuring with rising edge of the probe, without
clearing the distance to go
MEAW=-1 G1 X... Y... Z... F... ; Measuring with falling edge of the probe, without
clearing the distance to go
CAUTION
For MEAW: Measuring probe travels to the programmed position even after is has
triggered. Risk of destruction!
Measuring job status
If the probe has switched, the variable $AC_MEA[1] after the measuring block has the value
=1; otherwise, value = 0.
At the start of a measuring block, the variable is set to the value=0.
Measuring result
When the probe is successfully activated, the result of the measurement is available for the
axes traversed in the measuring block with the following variables after the measuring block:
in the machine coordinate system: $AA_MM[
axis
]
in the workpiece coordinate system: $AA_MW[
axis
]
Programming example
N10 MEAS=1 G1 X300 Z-40 F4000 ; Measurement with deletion of distance-
to-go,
; Probe with rising edge
N20 IF $AC_MEA[1]==0 GOTOF MEASERR ; Measuring error?
N30 R5=$AA_MW[X] R6=$AA_MW[Z] ; Processing of the measured values
..
N100 MEASERR: M0 ; Measuring error
