1. An electric drive (10), comprising:

  • a drive controller (5);

    an electric motor (9); and

    a control device (3, 4, 7, 8) configured to register and monitor threshold values of axis-based, electrical/mechanical operating state variables,wherein 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, wherein the additional monitoring is active independently of the monitoring of the threshold values, such that said possible deviations from predefinitions and conditioning of the analytical result are detectable before the monitoring of the threshold values.
