6.16.2 Saving a Base Position
The procedures for saving the current object position as a base position are described below. Before saving a
base position, set inspection conditions first and check to make sure that the edges were detected after testing.
When a live image is displayed, a base position is saved after capturing a new image. When a memory image is
displayed, the current memory image is saved as a base position without capturing any image.
Registration Procedure
1.
Select the "Base Position" tab.
The cursor moves to "Base Setting".
2.
Press the ENTER key.
When the dialog message appears, choose "YES" to continue.
If the edges were correctly detected and the base position was saved, the
following data appears.
Under the Base Position tab
Corr.: Correlation value of the first sorted image
Adj. X: 0.0
Adj. Y: 0.0
Base Pos. X: Coordinate X of correlation value of the first
sorted image
Base Pos. Y: Coordinate Y of correlation value of the first
sorted image
In the Message area
Judgment: OK
Corr.: Correlation value of the first sorted image
Adj. X: 0.0
Adj. Y: 0.0
If the PV310 failed to detect object, the following message appears. Check the template image, size of
search area, etc.
E0042 Base position cannot be detected.
6.16.3 What To Do If You Faced a Trouble
Judgment result is always NG.
This is attributed to the following causes.
The object could not be detected
Recheck and reconsider the template image, the settings of search area size and the setting value for
sequence.
No base position is saved.
The error code "E0049" may be displayed. Since any base position is not saved, the PV310 cannot work
properly. Note that if you change the template and the position and size of the search area after saving a
base position, you need to save the base position again.
Position Adjustment checker that refers to adjustment amount cannot detect the object.
If Position Adjustment is saved as any number except "0", the adjustment amount of Position Adjustment
or Rotation Adjustment that is saved as the number is referred. If the Position Adjustment or Rotation
Adjustment checker failed to refer to the adjustment amount, it cannot detect the object. The PV310 does
not function properly and outputs "NG" result.
