A automatic time: photoelectric detection signal - to be converted by level - to be emitted by PLC system - shear signal - to apply speed setting - to fly shear acceleration - from zero start - to shear point - to brake - to give the crawling command - to the swinging position - to give the backcrawling command - to give the backcrawling command until the cutting edge reaches zero - to send the stopping command by PLC.

　B manual time:

C breaking operation: that is, continuous ruler cutting in case of accident. After the operator station is given the breaking signal, the position of the photoelectric detection signal and the cutting edge is blocked through photoelectric isolation. At the same time, the signal is sent to PLC through the conversion of the level. The PLC sends the breaking command, and the breaking speed is given. After breaking, remove the lock on the position signal of the flying shear blade. The cutting blade is the same process when pressing the cutting head. After running an action cycle, it stops on the parking space。
