4.1.2.5  Electronic control system
：Kunlun Kuntai 7inches touch screen, Siemens PLC，Yaskawa frequency converter, Schneider low-voltage apparatus.
a. The whole line uses PLC control, Liquid crystal touch screen, human-computer interface to realize the interaction between the PLC and human. Operator via the setting procedure to automatic operation and monitor the control process to realize that the operator control the whole line and change the control parameter, and monitor the running status, parameter and failure indication of the equipment. Length of the work piece is set by digital, the length of the work piece can be adjusted.  
b. Operating mode is including manual/automatic. The machine has manual and automatic switch function. The machine is stand-alone run within the manual status, it is easy to maintain. Within the automatic status to proceed the whole line running, sequence start-up. The whole has jerk button in order to handle the emergency episode, which can guarantee the machine and operator safe.
