NOTE
In the MDI mode, cutter compensation C (M series) or tool
nose radius compensation (T series) is not performed,
irrespective of the setting of this parameter.
QCR The travel distance of circular interpolation in cutter compensation C (M
series) or tool nose radius compensation (T series) is judged:
0 : In the FS16 format.
1 : In the FS15 format.
FS16 and FS15 determine the travel distance in different ways if the
radius of arc at the start point of circular interpolation is different from that
at the end point (if the end point is not on the arc). By this parameter, the
method of determining the travel distance of circular interpolation can be
selected.

If the end point viewed from the start point is
in the A region, the movement is made along
the shortcut. If the end point is in the B, C,
or D region, almost a single turn is made.

If the end point is in the A region separated
by the line L drawn between the start point
and the center, the movement is made along
the shortcut. If the end point is in the B re-
gion, almost a single turn is made.
