The area output ranges preset in the controller are compared with the table position, and the AREA
output signals are activated by the controller when the table is within the preset range. Based on these
output signals the dimension of the workpiece can be judged to be good or bad, and workpieces of
different size can be differentiated.
It is possible to output up to 31 preset positions using the CEU5 Multi-counter.
