Abstract:
1. A machine, comprising: at least two wheels arranged on a base body, with at least one of the wheels being driven; a revolving belt coupling the at least two wheels with one another; a transmitter arranged on the base body and transmitting contactless to the belt a transmitted signal having an oscillation frequency; a receiver arranged on the base body and receiving from the belt a reflected signal in response to the transmitted signal; and an evaluation device connected to the receiver and checking if the reflected signal received by the receiver satisfies an acquisition condition indicating that a speed of the belt is in a predetermined speed range, wherein the evaluation device determines, if the acquisition condition is satisfied, a frequency spectrum which is based on the oscillation frequency and the reflected signal in the predetermined speed range and indicative of a mechanical oscillation characteristic of the belt, and generates a control signal based on the determined frequency spectrum.
