The article includes a description of the validation used for an assessment of accuracy of measured symptoms in case of distributed drives connected via the ProfiBus DP network. Particular attention has been given to acquiring the diagnostic data especially in case of currents intensities in the start-up and braking phases. The authors also raise a problem of the usefulness and precision of measured data obtained with usage of recording methods by means of dedicated system in comparison with the solutions delivered by the manufacturer of examined drives. Presented results of practical measurements contain values based on the registration of output currents of frequency converters and the measured values of current intensities in the motor windings. The described parameters are significant for the evaluation of electrical damages, caused by various factors (including excessive loads, improper selection, etc.). [ABSTRACT FROM AUTHOR] |
