A method for the diagnosis of natural vibrations in a mechatronic system, includes at least one rigid body (WT 1 , WT 2 ), which is moved relative to another rigid body (S) by means of at least one numerically-controlled drive, whereby the natural vibrations are caused by the drive (A 1 , A 2 ) and are detected by sensors (WM 1 , WM 2 , N 1 , N 2 , BA 1 , BA 2 ,) internal or external to the system. The drives (A 1 , A 2 ) can be used as a system-internal, vibration-generator, so-called rotatory shakers, by superimposing white noise on a constant speed for the drive, or by wobbling the frequencies.
