Abstract
The invention relates to an electric drive (19) provided with a drive regulator (5), an electromotor (9) and a control device (3, 4, 7, 8) which is used to detect and monitor the threshold value of axis-relevant, electrical/mechanical operational state variables, and preventative error diagnosis. The control device (3, 4, 7, 8) comprises an additional monitoring device (6) which can analyse the operational state variables in order to recognise, at an earlier stage, possible deviations from tolerance ranges and to process the analysis results
Claims12
Electric drive (10) having a drive controller (5), an electric motor (9) and a control device (3, 4, 7, 8) with registration and monitoring of the threshold values of axis-relevant, electrical/mechanical operating state variables, characterized in that the control device (3, 4, 7, 8) comprises additional monitoring (6) with analysis of the operating state variables for the early detection of possible deviations from predefinitions and conditioning of the analytical result.
