Title: DEVICE AND METHOD FOR DETECTING ERRORS IN MACHINES
Abstract:
The invention relates to a method for detecting errors in a machine (1) comprising at least one electric device unit (3) for driving a machine assembly. The frequency spectrum of a measurement variable characterizing the electric power consumption of the drive unit (3) is determined and in an analyzing step, the frequency spectrum evaluates the measurement variable with respect to errors indicating abnormalities.
