When a corner is determined to be an inner corner, the feedrate is
overridden before and after the inner corner. The distances Ls and Le,
where the feedrate is overridden, are distances from points on the beam
center path to the corner (Fig. 5.4.2.1 (b), Fig. 5.4.2.1 (c), Fig. 5.4.2.1 (d)).
Ls and Le are set with parameter Nos. 1713 and 1714.

FIg. 5.4.2.1 (b) Override Range (Straight Line to Straight Line)
When a programmed path consists of two arcs, the feedrate is overridden
if the start and end points are in the same quadrant or in adjacent quadrants
(Fig. 5.4.2.1 (c)).

Regarding program (2) of an arc, the feedrate is overridden from point a
to point b and from point c to point d (Fig. 5.4.2.1 (d)).
