(1) Outline

The positional deviation measurement (one point search) in measurement 0 allows the degree of

match and coordinates to be measured, and the result, OK or NG, is output.

Coordinate (model 0-X): 200.0 to 250.0

Coordinate (model 0-Y): 150.0 to 200.0

Degree of match (model 0): +09500 to +10000

(3) Final output conditions and ladder circuit
