Note
If the program is deflected in the program, the variable is set to 1. At the start of a
measurement block, the variable is automatically set to the initial state of the probe.
Reading measured values
The positions of all traversing path and positioning axes of the block are acquired (maximum
number of axes depending on the control configuration). In the case of
decelerated in a defined fashion following the triggering of the probe.
Note
If a geometry axis is programmed in a measuring block, the measured values are stored for
all current geometry 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.
Reading measurement results
The measurement results for the axes measured with probes can be read via the following
system variables:
● $AA_MM[<axis>]
● $AA_MW[<axis>]
No internal preprocessing stop is generated when these variables are read.
Note
A preprocessing stop must be programmed with
program. The system will otherwise read false values.
