Reposition the tool at any point on the arc between the start and the end
point 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 tool position (see documentation prepared by the
system installer).
After the axes have been positioned at a point on the arc press the
{RECORD MID PT} softkey. The control will store the current tool
position as the second point on the arc.
Important: If an axes is moved that is not in the currently defined plane
(G17, G18, or G19) the control will interpret the move as a helical move and
generate the block accordingly. (see helical interpolation in chapter 14).
