Abstract: PROBLEM TO BE SOLVED: To accurately diagnose abnormality in machine installation by performing the spectral analysis of the load current signal of an electronic motor, and comparing a calculated diagnosis parameter with a criterion value being set to each machine installation to be diagnosed in advance. SOLUTION: A load current I of an electric motor 14 is detected by a current detector 18, and a load current signal (I) is converted to a voltage signal V by a current-voltage converter 19 and is converted to a digital signal VD by an A/D converter 20. Based on the signal Vd , the frequency spectrum of the load current I is obtained by fast Fourier Transform at a spectrum analysis part 22 of a comparator 21. Then, an average order nave or a dispersion order nvar of the power supply frequency of the electric motor is calculated as a diagnosis parameter based on a current spectrum SP at a diagnosis parameter calculation part 23. Then, the ratio of the value itself of the diagnosis parameter being calculated at a failure judgment part 24 to the diagnosis parameter when the same facility is normal is compared with a criterion value C.  When the value is larger than the criterion value C, it is judged that a machine facility 11 is abnormal.
