Solution of ESTUN embedded CNC system in three-roll plate bending machine

The application of ESTUN embedded CNC system in the three-roll plate bending machine has been described in detail in the text. Based on DSP technology, the system has equipped with a variety of hardware port, built-in subsystem of HMI and real-time control subsystem. The two subsystems can realize the real-time communication via DPRAM technology, which can control the moving parts accurately. Specific applications are as follows： automatically controlling pre-bending length; automatically pre-bending; automatically round rolling; automatically saving and using of processing program; controlling frequency sensitive resistor; star triangle controlling of cylinder, back-up roller and electromotor; reverse delay controlling of motor; synchronous controlling of two cylinders of upper roller; manually and automatically resetting of encoder; security conflict controlling of operating buttons; encoder failure detection; condition monitoring; free configuration of ports, etc.
