There are four commands to make point-to-point movement in robot groups. There are two
commands to interpolate the motion (
MOVE
and
MOVES
) and two commands to define the
target point (
JOINT
and
LOCATION
). The total combination of these gives four options.

ONTOURING
Contouring connects different motions by defining the final velocity for each movement. This
way, the motion does not stop at the segment. It is continued with the next motion. This
method is applicable in one-axis applications, but has several drawbacks that become more
prominent in multi-axis applications:
The angle between the movements' direction must be zero. Otherwise, a jump in
velocity occurs.
It is not possible to connect arc with linear segments without a jump in acceleration.
You must calculate the achievable final velocities on each segment to stop after the last
segment.
