Abstract: In an exemplary method for condition monitoring of electric and mechanical drives, measurement data in a condition monitoring system of electric drives is collected at least from one electric drive. The measurement data is pre-treated, a frequency spectrum is created from the pre-treated measurement data with the Fast Fourier Transform transformation, and a detected vibration frequency and vibration amplitude are recorded from the frequency spectrum. The detected vibration frequency and vibration amplitude is compared to at least one detected vibration frequency and vibration amplitude successive in time. In the comparison, detrimental changes in vibration frequency and vibration amplitude are defined, and the detrimental changes are indicated.
