| 20080215164 | Method and Device for Controlling Movement of a Movable Machine Element of a Machine - The movement of a machine element associated with a machine axis of a machine is simulated with a model by inputting in the model a movement to be performed by the machine element, and determining with the model at least one of a position profile, a velocity profile and a torque profile suitable for optimized movement of the movable machine element, as well as a predetermined quality function and a limitation for the movement of the machine axis. The position profile, velocity profile or torque profile is then used as a reference or pilot control variable in a control loop to control the moving machine element. The predetermined quality function is an integral of the square of a torque or of a variable which is directly related to the torque. The method can be used to optimize the guided movement of the machine element. | 09-04-2008 |

| 20090302699 | METHOD FOR MOUNTING A BODY - In a magnetic bearing arrangement, support coils are connected in series and can be fed with a current. By coupling a point connecting the two support coils to a voltage source, the support coils can be used as actuating elements and, by feeding the support coils with voltage pulses, the inductance of the support coils can be inferred which is an indication of the position of the body to be mounted. This provides for a position control arrangement. Using one and the same support coils, both a stably controlled load-bearing capacity can thus be produced and at the same time a position sensor can be replaced. | 12-10-2009 |
| 20090309454 | PIEZOELECTRIC ACTUATOR - A piezo actuator includes an adaptation element, which is configured to adapt the piezo actuator to a controller for inductive loads, particularly to a converter for actuating inductive loads. The adaptation element allows use of controllers or converters of numerical control systems, which normally are used for actuating servo motors. Therefore it is no longer necessary to provide specially designed hardware for the actuation of piezo actuators, but instead the above-mentioned controllers can be used. Furthermore, as a result of the adaptation element, the piezo actuators can be integrated in the bus of the numerical control system. This allows communication in real time via the NC bus. | 12-17-2009 |
