Significance
The PTP and CP commands act in a modal manner. CP is the default setting.
If modal applies when programming the STAT value, TU programming is = <...> non-modal.
Another difference is that programming a STAT value only has an effect during vector
interpolation, while programming TU is also evaluated during active rotary axis interpolation.

point to point (point to point motion)
The movement is executed as a synchronized axis movement; the slowest axis
involved in the movement is the dominating axis for the velocity.
continuous path (path motion)
The movement is executed as Cartesian path motion.
Position of the articulated joints; this value is dependent on the transformation.
TURN information acts blockwise. This makes it possible to clearly approach axis
angles between -360 degrees and +360 degrees.
