A Path object manages coordinated multi-axis motion profiles.
It is used when the motion profiles in an N-Dimensional space are
required to follow a specific coordinated trajectory. Motion paths
are constructed with high level linear and arc segments and downloaded
to the controller. The controller calculates the real-time individual
axis profiles.
Generally, Path motion is used when the trajectory through space
is more important than the final target position. Several different
algorithms can be applied to convert the linear and arc segment
path into an interpolated trajectory.
Path trajectory generation is now supported by PT, PVT, SPLINE,
BESSEL, BSPLINE, and BSPLINE2 algorithms. Blending of the corners
is only available for the 2 bspline algorithms. Blending of a corner
is when the path does not hit the corner but goes through a smooth
arc.
