Control for use in an automation system, including a processor having a communication port for a communication with a sensor and for a reception of sensor signals and a control port for providing control signals, a supply connected to the control port and adapted to provide a variable electrical supply voltage at a supply port in dependence on a control signal level of the control signal, wherein the communication port, the communication port and the supply port are connected to an interface adapted for electrical connection to a sensor, wherein the processor is adapted for providing at least two different communication protocols at the communication port and for providing at least two different control signal levels at the control port.

Control for use in an automation system

An input device including an input circuit with an input connection point for applying an input signal and with an input signal path which leads from the input connection point to an evaluation input and on which a conversion of the input signal into an evaluation signal is effected, an evaluation device which includes the evaluation input and which is designed to recognise an input signal level of the input signal on the basis of the evaluation signal, wherein the evaluation device is further designed to carry out a functionality test of the input device and within the framework of the functionality test by way of providing a test signal to effect a first change of the evaluation signal and to test the functionality of the input device on the basis of the effected first change of the evaluation signal, wherein the input circuit includes a transistor which is connected into the input signal path, and the input circuit is designed to control a control terminal of the transistor on the basis of the test signal, in order to effect the first change of the evaluation signal.

Input device, control apparatus and method for operation of an input device

A motor controller including a control unit designed for receiving and/or processing a movement signal and for outputting a control signal depending on the movement signal, and including a power stage which is designed for enabling an electric energy flow as a function of the control signal, and further including a sensor designed for detecting a movement of the electric motor and for providing a movement-dependent sensor signal to a sensor input of the control unit, wherein the control unit is designed for detecting a usage-dependent load value for a movement system driven by the electric motor and wherein the control unit includes a component memory for storing parameters of components of the movement system, a processing device for combining the parameters with incoming sensor signals to produce a load value and a load value memory for storing the established load value.

Motor controller and method for operating a motor controller

A method for operating a linear motor assembly includes: open-loop controlled introduction of electric energy to a first stator segment provided with solenoids for an open-loop controlled provision of a magnetic field for a permanent magnet arrangement of a conveying means for a generation of drive forces, and closed-loop controlled introduction of electric energy to a second stator segment provided with a measuring device for a detection of a position of a conveying means and with solenoids for a closed-loop controlled provision of a magnetic field acting on the conveying means, wherein a controlling device effects a temporary switch-over of the second stator segment from a closed-loop controlled state to an open-loop controlled state at a transition of the conveying means from the first stator segment to the second stator segment, and/or at a transition of the conveying means from the second stator segment to the first stator segment.
