1. Mark Type
Select the mark type from the dropdown list.
The item selected here will be displayed on the Mark Type column in the upper grid.
2. Database Number
Shows the database number when the parameter values were copied from the database.
When you want to copy the parameter values from the database, press the [Database] button to open the database list.
Then select the copy source data and press the [Set] button to make a copy.
3. Badmark Mark Rev
Select “Normal” or “Reverse”. When “Normal” is selected, the machine continues operation as long as no badmark is
detected. When “Reverse” is selected, the machine performs work when a badmark is detected.
4. Temperature, +Pressure, -Pressure
Use these fields to make a note.
5. Upper Limit, Lower Limit
Set the upper and lower limits of the range in which the measurement result is effective. Enter these limits in millimeters.
The downward direction is positive (+) and the upward direction is negative (-), just as with the head coordinate system.

Setting Description Example
Circle
Square
Triangle
Sp. Shape

TIP
If you use a special mark composed of two or more objects, set the Algorithm Type parameter (described later) to
“Pattern”. In this case, the “Shape” parameter is ignored during recognition, so you can set this parameter to any
type. (For more details, see “6.6 Pattern matching” in this chapter.)

A, B: Mark Out Size
Referring to the table below, enter the correct value in the mark size. This parameter is not displayed when "Mark Type"
of the Basic parameters is set to "Badmark". The Search Area parameters appear instead.

D: Outline (mm)
This parameter is displayed only when the Shape Type parameter is set to “Sp. Shape”. Enter the perimeter of the mark in
mm.

NOTE
A recognition error may occur due to environmental conditions such as illumination. In such cases, enter a larger
value than previously used for “Tolerance” of the Vision parameters, or set the tolerance to 100%, then perform the
vision test in the Mark Adjust mode and enter the obtained data on the area and perimeter. (The mark area and
perimeter values are displayed after the vision test is complete.) Return the tolerance to the original value after the
data is obtained.
