  • Patent number: 10974385
    Abstract: Movable elements of a machine are moved by a control device of the machine by controlling drives of the machine. To monitor the movement of the movable elements for collision with each other or with a stationary element, two monitoring devices check, independently from each other, using a computer program, whether there is a risk of collision in the working space. Depending on whether the monitoring devices detect a risk of collision or not, they intervene, independently from each other, in a corrective manner, in the control of the drives or not, and/or independently emit an alarm message or not. The two computer programs are designed in a diverse manner. The two monitoring devices differ from one another. One monitoring device is identical to the control device, while the other monitoring device is embodied as an industrial PC with a data link to the control device.

  • Patent number: 8239057
    Abstract: A method for controlling several master axes in a machine, for example a production machine includes the steps of defining profiles of desired values for a plurality of master axes, determining for each master axis a current desired value and also a current desired value for a slave axis using a logic combination rule, controlling a first drive in accordance with the current desired value of the slave axis, and if the dynamics controlling the first drive exceeds an upper dynamics limit, starting at the next clock pulse to modify determination of the current desired values for at least one of the master axes, and controlling the first drive with a reduced dynamics until the reduced dynamics falls below a lower dynamics limit.
