Provided is a deployment platform for deployment of an industrial application on an edge computing device, ECD, connected to the controller of a machine tool, MT, the deployment platform including a model management component, MMC, adapted to instantiate a generic machine tool model, GMTM, stored in a memory to provide a machine instance model, MIM, of the respective machine tool, MT, on the basis of a machine tool data report, MTDR, received by the model management component, MMC, from the edge computing device, ECD, of the respective machine tool, MT, and further adapted to convert generic data requirements, gR, of a generic industrial application into machine tool specific requirements, mtsR, using the machine instance model, MIM, of the respective machine tool, MT, wherein an instantiated industrial application for the machine tool, MT, is provided by instantiating the generic industrial application by extending its configuration data with machine tool specific requirements.

Method and platform for deployment of an industrial application on an edge computing device of a machine tool

A method and edge device for controlling data exchange of an industrial edge device with an industrial automation arrangement and a data cloud, wherein the edge device includes a first communication connection to the industrial automation arrangement and a second communication connection to a network of the data cloud, where the edge device includes applications exchanging data, and where the edge device includes a control device to control the data to be exchanged, wherein whether data exchange of an application is controlled via the first communication connection and the data exchange is implemented directly via the second communication connection or vice versa is defined for each application, where a data flow control device ensures simultaneous direct data exchange by an application via both communication connections does not occur, such that rigorous checking of applications or containers within the applications with respect to data security is not required.

Method and arrangement for control data exchange of an industrial edge device

A compensation of cyclical interferences occurring during operation of motor controlled by an electrical motor drive comprising the controllable motor and a speed governor, wherein a position determiner is provided for continuously determining a position of said motor, responsive to a position signal indicative of said position of said motor and wherein a load observer responsive to a first output signal received from said position determiner and to a second output signal received from the speed governor is provided for generating a load signal indicative of an estimated load and continuously applying said load signal to an output of the speed governor.

Electrical motor drive and method for operating such electrical motor drive

A method and a device may be used for controlling the working points of a series-resonant-circuit inverter. The frequency of the inverter is controlled as a manipulated variable in dependence upon a defined phase-angle system deviation in such a way that a determined phase-angle actual value of a measurable state variable of the load circuit, whose phase-frequency characteristic has a monotonically falling curve, corresponds to a specifiable phase-angle setpoint value. Thus, a method and a device are implemented for controlling the working points of a series-resonant-circuit inverter, by which means the operating range prescribed for the series-resonant-circuit inverter is detected and kept stable independently of parameter fluctuations of the resonant circuit elements.

A method and a device for controlling a sensorless, field-oriented asynchronous machine, wherein a manipulated variable space vector and a stator frequency are calculated, by means of a two-component current control system, from which control signals are generated using a space vector modulation process. A PI controller of an EMF control system for the d-component of a calculated EMR space vector of the field-oriented control system is deactivated and its output signal set to zero at a stator frequency, determined as a function of a calculated d-component of a calculated EMF space vector and a calculated stator frequency, that is less than or equal to a first limit frequency. Thus, the method may be used for speed control of a sensorless, field-oriented asynchronous machine down to a full stop.
