Read reference radius
The value of the reference radius of a rotary axis can be read using system variables:
• For the display in the user interface, in synchronized actions or with a preprocessing stop in the part program
via the system variables:
• Without preprocessing stop in the part program via system variable:
If no values are programmed, the default 360mm/(2π)=57.296mm (corresponding to 1mm per degree) will be
read in both variables.
For linear axes, the value in both variables is always 1 mm.
$AA_FGREF[<axis>] Current main run value
$PA_FGREF[<axis>] Programmed value
