Resumo
A new family of products especially designed for automation and electrical drive control is here introduced. By means of a single hardware platform and real time IEC 61131-3 PLC programming it’s now possible to integrate the control for both AC and DC motors with complex and demanding process control functions, e.g. flying shears, mill references cascade, loop and tension controls, impact drop compensation and so on. New generation processors and reconfigurable FPGA are the essential elements of such powerful and compact solution, able to satisfy custom plant necessities. By means of real-time drive interfaces based on Ethernet, or more traditional fieldbuses, it’s possible to distribute in the plant technological functions at lower costs, minimizing the cabling and reducing at the same time the complexity of any external automation controller. Designed adopting all last technological standards, the new control system integrates advanced functions for motor speed and torque regulation together with dedicated software libraries for process control, particularly useful in Rolling Mills. Its modularity and openness allow providing solutions from the stand- alone application (motor drive and machine control) to the overall management of a plant (distributed process control), with easy integration with the pre-existing automation. Some application examples will be explained.
