Measuring mode

Measuring commands MEAS and MEAW
The measuring operation is activated from the part program. A trigger event and a
measuring mode are programmed.
A distinction is made between two measuring modes:
● MEAS: Measurement with deletion of distance-to-go
● MEAW: Measurement without deletion of distance-to-go
The measuring job is aborted with RESET or when the program advances to a new block.
Note
If a GEO axis is programmed in a measuring block, then the measured values are stored for
all current GEO axes.
If an axis participating in a transformation is programmed in a measurement block, the
measured values for all axes participating in this transformation are recorded.
Probe status
It is possible to scan the probe status directly in the part program and in synchronized
actions.
$A_PROBE[n] where n=probe
$A_PROBE[n]==1: Probe deflected
$A_PROBE[n]==0: Probe not deflected
600
Example:
N10 G01 F300 X300 Z200 MEAS=-2
Trigger event is the falling edge (-) of the second probe (2).
Example:
N20 G01 F300 X300 Y100 MEAW=1
Trigger event is the rising edge of the first probe (1).
