  • Method for operating a system with drives, which are mechanically coupled together, and with a higher-level computer, and system
    Patent number: 10797621
    Abstract: In a method for operating a system with drives, which are mechanically coupled to one another, and with a higher-level computer, which is connected to the drives with the aid of a data-bus connection, and a system, a respective actual torque value is determined in each drive and transmitted to the higher-level computer, in particular using a data-bus connection. The higher-level computer determines for each drive a setpoint torque value allocated to this drive, the higher-level computer has controllers, and one of the controllers is allocated, in particular biuniquely, to each drive. The controller allocated to the respective drive controls the actual torque value of the respective drive to the setpoint torque value of the respective drive by determining a setpoint speed value allocated to the respective drive as the control value and transmits it to the respective drive, in particular with the aid of a data-bus connection.
