摘要： In order to enable a moveable part of an adjusting device of the wind power plant to be held securely on a wind power plant, drive axles are tensioned against each other prior to the holding action, by at least one drive axle being rotated relative to the other drive axles, and by maintaining a tension of the drive axles achieved at the beginning of the holding action by control of the drive axles and by implementing a position control of the drive axles, which controls the drive axles to the respective starting positions of the drive motors of the drive axles at the beginning of the holding action.

摘要： A method for inductive energy transmission between a primary part and a secondary part, wherein a primary current is introduced into a transmitting coil arranged on the primary part in order to create a first magnetic field which induces an electrical AC voltage in a receiving coil arranged on the secondary part, which electrical AC voltage causes an electrical secondary current at the secondary part and thus a power flow to at least one load connected to the receiving coil, which power flow comprises an uncompensated active power, it is provided that a compensation unit introduces a compensation current into a secondary-side coil, which compensation current generates a second magnetic field which is superimposed on the first magnetic field and induces a compensation voltage in the transmitting coil. The compensation voltage changes the phase shift between the primary voltage that drops across the transmitting coil and the primary current flowing through the transmitting coil in such a way that the transmitted active power is increased.

摘要： For determination of the position of a movable component with a plurality of position magnets relative to a stationary component with a plurality of position sensors, it is provided that the sensor responses are detected for a group of position sensors in the region of the movable component, sensor model responses of the group of position sensors are determined from a sensor model for a plurality of assumed different relative positions of the movable component relative to the stationary component, the sensor model responses are compared with the sensor responses and the assumed relative position with the smallest deviation between the sensor model responses and the sensor responses is used as the relative position of the movable component.

摘要： Hot foil stamping machine stamping a foil onto a substrate, which improves stamping quality under changing conditions, includes a control unit for controlling the temperature of the stamping interface surface to a predefined desired temperature. The control unit receives at least an actual temperature of the heating plate from the at least one temperature sensor and provides a manipulated variable to the at least one heating device. Further, the stamping machine includes a state observer for estimating an actual temperature of the stamping interface surface of the at least one stamping plate based on a physics-based analytical model of the heat transfer between the heating plate and the stamping plate. The control unit also includes a feedback controller for calculating the manipulated variable for a heating device based on the predefined desired temperature and the estimated actual temperature of the stamping interface surface provided by the state observer.

摘要： In order to implement a method for data flow control in a network with reduced overhead, a first subscriber transmits data symbols in data frames to a second subscriber. The second subscriber forwards and/or processes the data frame. If there is a delay in forwarding and/or processing the data frame, the second subscriber instructs the first subscriber to pause the transmission of the data frames with a granularity of one data symbol. After the pause, the first subscriber continues to transmit the data frames with a granularity of one data symbol.

摘要： In order to at least temporarily increase the throughput of transported objects in a transport device in the form of a planar motor, without negatively influencing the movement of the transport units, at least one engagement portion is provided on each of the at least two transport units, it being possible for the at least two transport units to be moved in succession in the transport plane in a direction of movement into an engagement position in which the engagement portions of the transport units are at least partially engaged. The engagement portions are designed to overlap with one another in the engagement position at least in the direction of movement such that a total extent of the transport units in the direction of movement is smaller than a sum of the individual transport-unit extents of the transport in the direction of movement.

摘要： In order to ensure particularly good protection of individuals in an electromagnetic transport system, a safety area is provided in a transport area. Furthermore, a safety function is provided which, in accordance with a predetermined safety requirement level, ensures that the transport unit reaches the safety area at a speed less than or equal to a safety speed and/or with a transport unit force less than or equal to a safety force and/or a transport unit energy less than or equal to a safety energy, or prevents the transport unit from reaching the safety area.

摘要： In order to specify a flexible transport arrangement for a long stator linear motor which can be used more flexibly for the transport of products, a transport arrangement includes a transport unit and a product carrier. The transport unit and the product carrier each have at least one guide element arranged in the direction of movement and transport unit has drive magnets arranged in a direction of movement for driving the transport unit. The product carrier has no drive and is couplable to the transport unit via a coupling point and is drivable by the transport unit via the coupling point.

摘要： Method for time synchronization in a network comprising masters and at least one slave. The slave receives synchronization messages from the masters via the network for time synchronization of a first clock and a second clock of the slave. A first master sends a first synchronization message having a first time stamp to the slave for time synchronization of the first clock. The slave calculates a clock rate and a time difference between the first clock and the first master and aligns the first clock with a synchronized time. A second master sends a second synchronization message having a second time stamp to the slave for the time synchronization of the second clock. The clock rate of the second clock is set to the first clock rate. A time difference between the second clock and the second master is calculated and the second clock is aligned with the synchronized time.

摘要： For a kinematic modelled in a kinematics coordinate system by hingedly interconnected single axles, a method calculates a braking region possibly covered by at least one of the single axles connected to an origin of the kinematics coordinate system and at least one of the single axles moving relative to the origin. In the event of a braking process, for a point that is coupled to a single axle, at least one virtual end position of the point is determined from an initial position of the point, a vectorial speed of at least one single axle, and a minimum deceleration of at least one single axle. The braking region of the point is determined using an envelope of the initial position and the at least one virtual end position, the extent of the envelope being calculated from the initial position and the at least one virtual end position.
