Search Patterns With
Origin Proximity Signal
There are basically three possible search patterns when an origin proximity
signal is present (i.e., when DIP switch no. 3 is ON). The pattern executed
depends on the position of the origin with respect to the starting position and
search direction. N.O. inputs are used in the following example diagrams.
Example 1
The first diagram illustrates the simplest search pattern, i.e., that in which
both the origin proximity and origin signal activation points are in the search
direction from the initial position.
