AMP-204C / AMP-208C
Bit 17: Blending movement - BLD
Continuous interpolation has several speed succession method.
The blending method has a transition region at the interconnection
points of two paths (as shown in figure below). The BLD signal
indicate that the axis is entering this area.

Bit 18 and 19: Pre- and post distance event
Every position movement command can set up pre-distance and
post-distance to trigger the controller to issue signals when
distance of movement meet given conditions.
The controller starts recording shift distance of movement when
point to point movement is started. When distance of movement is
greater than pre-distance, the pre-distance event occurs.
Similarly, when remining shift distance of the point to point
movement is less than the post-distance, then post-distance event
occurs. Relation between movement and signal shown in figure
below:
