Read measurement result
The measurement result is available for the axes acquired with probes in the following
variables:
• Under $AA_MM[axis] in the machine coordinate system
• Under $AA_MW[axis] in the workpiece coordinate system
No internal preprocessing stop is generated when these variables are read.
A preprocessing stop must be programmed with STOPRE at the appropriate position in the
program. The system will otherwise read false values.

Programming measuring blocks, MEAS, MEAW
When command MEAS is programmed in conjunction with an interpolation mode, actual
positions on the workpiece are approached and measured values recorded simultaneously.
The distance-to-go between the actual and setpoint positions is deleted.
The MEAW function is employed in the case of special measuring tasks where a programmed
position must always be approached. MEAS and MEAW are non-modal commands.
