necessary to describe an arc) of a circular move.
The screen changes to display the current wheel location in large
display characters:

end point by using any of the following methods:
Jog the Axes in manual mode
Automatically move the axes by executing a part program or MDI
program
Manually move the axes using any means as long as the encoder is
still actively recording the wheel position (see documentation
prepared by your system installer)
3. After storing the second point on the arc, reposition the axes at the
end point of the arc.
