6. INTERPOLATION FUNCTION
459
The distance between an arc and the center of a circle that contains the arc
can be specified using the radius, R, of the circle instead of I, J, and K.
In this case, one arc is less than 180_, and the other is more than 180_ are
considered.
For T series, an arc with a sector angle of 180_ or wider cannot be
specified (P/S alarm No. 023).
For M series, specify an arc more than 180_ with a negative radius value
commanded.
If Xp, Yp, and Zp are all omitted, if the end point is located at the same
position as the start point and when R is used, an arc of 0
is programmed.
