Arc interpolation commanding method
a) Commanding with a radius
CW <End point[P variable 1]> <radius[P variable 2]>
CCW <End point[P variable 1]> <radius[P variable 2]>
The start point is the current position, so the end point and the radius are commanded
in the above type, and only the P variable can be commanded. The P variable can be
indirectly designated as a L variable.
Disable the“
basic
parameter P61 I, J arc commanding method”. The X-axis value of the P
variable 2 is regarded as a radius. The Y value at this time has nothing to do with the
command.
If there is a start point, an end point and a radius, 2 circles are possible.
There are 4 arcs going from the start point to the end point like Fig.2.27. If a
direction is given here, then they reduces to 2 arcs such as a 180 or more degree arc
and a 180 or less degree arc going from the start point to the end point. The radius is
commanded as a negative number when commanding a 180 or more degree arc, and as a
positive number when commanding a 180 or less arc.
