The main features of the control system:
1. Multiple speed DC motor, tension control, and necessary logic control.
2. The unwinding and winding tension is given with automatic deceleration flick. The unloading and transporting of the roll are under control. All products are equipped with diameter calculation, movable fill, static fill, tension control, and belt protection.
3. Cooperated with the pressure sensors and displacement sensors, the encoders can achieve automatic liter deceleration and braking functions. The unit is also equipped with the functions of calculation of coil diameter, turns, and belt length.
4. On the HMI operation screen, there is an input function of the rolling process table. During the automatic rolling process, according to the parameters established in the automatic rolling process, the system can set parameters according to each of these variables, thus achieving automatically completion of the production of the strip of each volume. The operator can adjust some of the rolling process parameters, such as front and back tension value.
5. Troubleshooting. The products have been equipped with specialized diagnostic procedures. The status of various important signal can be dynamically displayed in the HMI screen, which can greatly reducing the time of the maintenance personnel to determine the fault and to find the point of failure.
