Patent number: 7664769Abstract: 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.

Publication number: 20070291518Abstract: A converter (34) includes a control device (6) connected at its output to a pulse width modulator (8), which is connected on the output side to control inputs of a load-side inverter (10), and a current measuring device (4), which is connected on the input side to two terminals of the load-side inverter (10), and on the output side to two measurement inputs of the control device (6). Further provided is a two-channel damping control circuit (38), whose control-circuit channels (56, 58) are each connected on the input side to an output of the current measuring device (4), and on the output side to an inverting adder (54), and the outputs of the two control-circuit channels (56, 58) and the output of the inverting adder (54) are connected to inputs of the pulse width modulator (8). As a result, a converter (34) is realized that can actively dampen a connected undamped inverter output-filter (36) without causing an additional control dead time.Type: ApplicationFiled: May 30, 2007Publication date: December 20, 2007Applicant: Siemens AktiengesellschaftInventor: DIETER ECKARDT

Patent number: 6999326Abstract: 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.Type: GrantFiled: February 20, 2004Date of Patent: February 14, 2006Assignee: Siemens AktiengesellschaftInventors: Dieter Eckardt, Peter Jänicke, Günter Schwesig

Patent number: 6822408Abstract: 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.Type: GrantFiled: January 29, 2003Date of Patent: November 23, 2004Assignee: Siemens AktiengesellschaftInventors: Dieter Eckardt, Ronald Hauf

Patent number: 6745083Abstract: 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.Type: GrantFiled: April 17, 2002Date of Patent: June 1, 2004Assignee: Siemens AktiengesellschaftInventors: Dieter Eckardt, Carsten Rebbereh

Publication number: 20040093357Abstract: A method for parameterizing an apparatus is described. An dataset with a parameter is inputted and transmitted to the apparatus and acknowledged upon receipt. The identity of the acknowledged dataset is checked by comparison with the inputted dataset, and the received dataset is released if the two datasets agree. The proposed parameterization method can be used to read in parameters, in particular safety-related parameters, at a predetermined memory location of the apparatus without introducing changes or errors.Type: ApplicationFiled: October 15, 2003Publication date: May 13, 2004Applicant: SIEMENS AKTIENGESELLSCHAFTInventors: Dieter Eckardt, Carsten Rebbereh
