In course of the continuing trend towards lightweight construction of fast positioning systems, cable feeders, sensor connections, power supply, etc., may have noticeable influence on the system behavior. To study the effects of such additional masses a multi-body model of a positioning drive, serving as a reference model, is built and compared with measurements. Since it turns out that this multi body model is unsuitable for the development of systems identification methods we strive for finding a proper, concentrated parametric mean value model that takes into account the variable mass. Finally, this model is used to test and evaluate standard methods for parameter identification based on Poisson moment functions.
