It is known that the magnetic parameters of the permanent and hybrid magnet undulators may be improved by sorting on basis of the magnetic measurements of individual magnetic blocks and applying of the optimization criteria. The procedure of sorting for the electromagnetic undulators HU256 is described in the article. The magnetic calculations of the individual dipoles and dipoles in ''undulator environment'' executed by means of Mermaid 3D Code and the magnetic measurements of the representative dipoles confirmed these magnetic calculations, and it allows us to get the main dependencies of the magnetic parameters of all dipoles from the mechanical characteristics (pole gap, yoke width, coil position). The criteria of optimization were conditions of weak influence of the insertion device on electron beam in the Storage Ring and high quality of undulator radiation. The 1st integral of the magnetic field and phase error have been minimized for sorting of the dipoles in undulators. The limitation of sorting connected with accuracy of mechanical measurements of individual dipoles is discussed.
