1. A system for identifying abnormal operation of a packaging machine, the system comprising:

  • a sampling entity arranged to sample a signal issued, when in use, to a servo-motor, the signal corresponding to torque values of the servo-motor;

    a spectrum analyzer for generating a spectral analysis of the sampled signal;

    a processing unit coupled to a storage device for storing a characterization of a mechanical element coupled to the servo-motor and corresponding to a state of operation, the characterization corresponding to at least one predetermined value for each of at least one frequency of the signal;

    wherein the processing unit is arranged to determine, when in use, abnormal operation of the mechanical element using the spectral analysis of the sampled signal and the characterization of the mechanical element.
