Reading measurement results
The measurement results for the axes acquired with probes are available in the following
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 STOPRE at the appropriate position in the
program. The system will otherwise read false values.
