In a method for operating an automation device having an internal finite state machine, a mapping unit, an internal data interface operatively connected for flow of information between the internal finite state machine and the mapping unit, and the mapping unit operatively connected for flow of the same information between the internal data interface and an external data interface of a communication module, state information of the internal finite state machine is routed to the mapping unit via the internal data interface, separate state information is derived from the state information received by the mapping unit, and the mapping unit then provides the separate state information to a communication unit of the communication module.

A drive control device having an inverter with semiconductor switches controlled by control signals is operated by calculating with a control logic a control signal time instant for each control signal, transmitting during operation the control signal time instants with the control logic during switching pauses of the semiconductor switches from a low-voltage side of the drive control device to a high-voltage side of the drive control device having the inverter, and generating the control signals for controlling the semiconductor switches on the high-voltage side based on the transmitted control signal time instants.

An automation system includes at least one automation object, with a directory for storing object names of the at least one automation object. An object name is assigned a directory entry which includes first information data as a reference to the automation object; second information data as a description of technological functionality; and third information data as a description of interfaces of the automation object. This results in immediate and permanent access to currently created (partial) solutions, so that parallel and/or distributed working on automation objects is possible.

The invention relates to a method for the automatic retrieval of engineering data from installations. The engineering and runtime objects are described by a uniform object model. This allows the correspondence between engineering objects and runtime objects to be determined at object level and no information is lost as a result of the mapping. In addition, a direct communication between engineering and runtime objects can take place, which can be utilized when the method is carried out.

An electronic power circuit includes at least one power semiconductor whose control inputs are connected to a trigger device and a power supply which, on the output side, is connected to terminals of the trigger device and, on the input side, is connected to an accessory device to which a supply voltage is applied. The power semiconductor is implemented as a self-conducting power semiconductor, which economically reduces the forward power losses and switching losses of an electronic power circuit.

Electronic power circuit

A drive system includes a central power supply with a line-commutated converter and a DC/DC converter connected downstream of the line-commutated converter, and a plurality of inverters, each inverter having an output connected a load, for example a motor, and a DC input connected to a regulated DC voltage output of the central power supply. Buffer capacitors are connected across the respective input and output of the DC/DC converter. The drive system further includes an energy recovery device with an input connected to the controlled voltage output of the central power supply and an output connected to at least two input terminals of the line-commutated converter. This type of drive system eliminates a bulky brake circuit.

Drive system

A drive controller for a self-commutated converter is described. The converter has two half-bridges, and the drive controller includes a corresponding control circuit for the converter valves of each half-bridge. Each control circuit can be connected via first switches to an external voltage. Each first switch is connected in parallel with a second switch, wherein the second switches are decoupled by way of decoupling diodes. The first and second switches can be alternatingly switched on and off. The switches can therefore be cyclically tested without interrupting service.

In a method of holding a machine element, whose position is directly or indirectly controlled by an electromotive drive in the absence of a self-locking mechanism, the drive is halted and a brake is activated to maintain the machine element in a holding position, without shutting down the drive which remain active. The drive is thus a safe drive constructed to securely prevent a re-starting although an inadvertent shutdown is not preventable.

Method of securing a machine element and/or a load connected to the machine element in a fixed position

In a method and device for monitoring speed, in particular for monitoring the rotation speed of an electric machine, two processors are employed which monitor the speed using different checking modes and cross-compare results. The first processor executes a conventional control algorithm and checks on the basis of an estimated or measured value of the speed whether a speed limit has been exceeded. The second processor determines the actual output frequency, which is also indicative of the speed, of a converter either from actual current values, which are measured anyway, or by reconstructing the voltage from control signals of transistors. Both processors thus monitor if a rotation speed limit has been exceeded and/or execute corresponding response actions. The method also recognizes faults in the power section based on the evaluation of the phase current. The system can also be designed to manage pulling loads.

The present invention relates to an automation system with at least one automation module (1), which has at least one automation object (A -An), and with function modules (F F ), which contain means for central management and maintenance of the automation objects (A An). As a result, a manufacturer-independent definition of new automation objects, possibly using already existing automation objects, becomes possible, costly separate programming of new automation solutions is no longer necessary at all or is at least significantly simplified.

The invention relates to a method and an apparatus ( ) for determining an operating state of a motor ( ) which is connected to a rigid network ( ) and has a rotation speed sensor. According to the invention, phase voltages (u , u , u ) of the rigid network ( ) which are applied to the connecting terminals (L , L , L ) of the motor ( ) are used to determine its frequency (f ) and amplitude (U ), a measured shaft rotation speed (n) and a number of pole pairs (p) of the motor ( ) are used to determine the slip (s) of the motor ( ) as a function of the determined network frequency (fn), and the mechanical shaft power (P ) is calculated as a function of this slip (s), of the determined amplitude (U ), of an internal voltage (U ) in the motor ( ) and of motor-specific parameters (X , X , X , R , R , R , &sgr;). A method which is independent of power is thus obtained for determining an operating state of a motor ( ), without any need to detect the actual current value.

Re-use and platform independence of application software is achieved by using component types comprising an interface and a body. This is followed by automatically generating components based on the developed component types. The development process steps are preceded by an adaptation process step, during which the functionality of all component types is defined for all the platforms.
