Imagine that you are drilling a hole, but in the middle of it all the power goes out and the drill breaks off. Regardless of which process you have just started, whether you are turning, milling or bending or in whatever form you are working on a workpiece: in the event of a power failure, the work step should be completed quickly and the tool moved out of the workpiece. This is usually achieved with an external uninterruptible power supply - or with a clever automation solution.
For this purpose, LTI Motion has developed the intelligent EtherCAT-based automation system SystemOne CM. It consists of the control MotionOne CM, the central rectifier unit and the attachable Mehrachsreglern ServoOne CM (CM = C ompact Multiaxis). The common DC bus serves as energy storage - even in the event of a power failure.
External capacitors can be connected here to increase the memory. However, the greatest amount of energy is undoubtedly achieved by regenerative braking of a rotating mass. The clever programming of the machine control allows the customer to keep the system alive in the event of a power failure or to shut it down in a controlled manner, for example by slowing down a rapidly rotating spindle.
This feature is particularly important in emerging markets where several power failures are commonplace in the seconds range. It is thanks to the special power supply unit that it is even possible to operate in the event of a power failure. The control voltage is obtained from a high voltage power supply, which is fed from the common DC bus.
This concept ensures that the control voltage for the controllers as well as for the central controller is available until the last drive is stopped.
Highest control performance, triple overload for high motor dynamics and compact dimensions characterise the automation system. The SystemOne CM also sets new standards in control technology: The integrated MotionOne CM control system is equipped with its scalable processor performance (Intel Atom with 1.3 GHz to Intel Core i3 with 2.2 GHz) for simple to highly demanding control tasks.
