* Resizing the provisional positioning windows
By modifying the second digit of [Prov. Position], you can resize the provisional positioning
windows.

* Provisional positioning windows referenced from Component center
So far, the provisional positioning windows were always referenced from the nozzle center.
Thus, sometimes that caused recognition errors because the windows were put far from the

referenced from the component center, not the nozzle center, no matter of the pickup offset.
Action: [Prov.Position] = 1**
Example: When [Prov.Position] is “100”, the Provisional positioning windows are put as below:

Note: The “Prov.Position=40~49” is not below, but see the “Prov.Position=30~39” as reference.
The former shows almost half size of window than the latter.
