The Items can be Confirmed in Sequence
No. of Objects
Number of the objects that were detected in each step.
Correlation Value*
Correlation value of the objects detected at each step. If multiple parts are detected in each step, the
lowest correlation value is displayed.
*Correlation Value for the Low Contrast Function
In the setting of "Low Contrast" for "Detect Mode", correlation may be different between the values displayed in
Sequence table and the values output as inspection results. This is because the PV corrects the decreased
correlation values that were affected by the distorted, chipped or overlapped parts of the object and output
them as inspection results. The correlation values in Sequence are the ones that have not been corrected and
the values in Result or output to the external devices are the ones that have been corrected. Therefore, the
former is lower than the latter. If there are many distorted or chipped parts over the whole object image, the
correlation values can be almost the same.
1.
Select "Sequence".
2.
Select "Recommendation Setting".
Regarding the current conditions, the recommendation values of sequence is set.
"Angle - Step" of "Inspection Condition" is also replaced to a recommendation value at the same time.
3.
Set "Square Correlation" to "Yes" as necessary.
4.
Select the table of sequence and change
Accuracy, Max. Count or Min. Correlation as
necessary.
The checker judges as "OK" when it detected the
number of "Max. Count" or more of objects.
How to Change Sequence
• To select the items, tilt the ENTER key left/right. To select the steps, tilt it up/down.
• To delete a step, select "0" for "Accuracy". All the steps after that are deleted.
• Maximum Count can be set per step, however, the value of later steps should be smaller than the value
of previous steps.
Example: If setting value of "3RD" is "5", the value of "4TH" cannot be set to "6" or more. If setting "4TH"
to "6", the values of "1ST" to "3RD" are automatically changed to "6".
