In normal mode, a central unit of an electronic control device receives desired and actual values for determining desired current values which are transmitted to an electronic drive unit. The central unit of the electronic drive unit receives the desired current values for determining drive signals for circuit breakers. In monitoring mode, the central unit of the electronic control device checks whether an connected electric motor is in a safe state. If not, the control device transmits disconnection signals to a disconnection device and to the drive unit. The central unit of the electronic control device generates checking information for the drive unit. In the monitoring mode, the central unit of the drive unit checks whether a disconnection signal is transmitted to the central unit and whether the checking information is correct.

Electronic control device of an electrical drive system with redundant disconnection device

The invention relates to a system and a method for user-specific intuitive and secure control of operational inputs in software components with operational surfaces. Various operational elements on a surface can be reached with varying ease for the input of data, or for carrying out a confirmation action, for example, an OK click with the mouse. It is made easier or more difficult for an operator to carry out an input. The above is achieved, whereby input means, for example, a mouse are either drawn towards, or withdrawn away from the corresponding input regions. Erroneous inputs are thus avoided.
