If sabnzbd download something like 2mins with 0kb/s speed is it possible that cancel and delete it automatically? With some script or something?

That usually means that the post is not present on the server.
Use the option Config->Switches->"Abort when download cannot be completed".

What that actually do if i enable it?

It's explained in the wiki. Just click the Help link on the option page.
