Today, editors summarize some of the photoelectric correction system some of the problems, I hope these can be helpful to users.

　1, photoelectric automatic correction system did not respond to how to do?
　Should be the electric eye is broken, you have spare no, there is a try.

　2, photoelectric correction, pneumatic correction, ultrasonic correction of three correction system works? What are their strengths and weaknesses?
　Photoelectric correction with more, relatively large temperature and humidity did not play the role of ultrasonic than the photoelectric point, but more expensive. Ultrasonic can be detected when the back then plc can know the specific value.

　3, in the photoelectric corrective control system, the role of a single electric eye and double-eye What is the difference?
　Electric eye correction is to improve the accuracy of electric eye, but also to a certain extent, make up for single-eye switch correction control system, the lack of precision, because single-eye correction switch large swing, and double the electric eye put his swing control in a smaller Of the range within the deviation when it does not slip to the side.

　4, optoelectronic corrective device components? Using photoelectric correction device can prevent the film to walk it, optoelectronic devices which have corrective components?
　Optoelectronic correcting device includes: a correction controller, a pusher, a sensor, works: the sensor detects material deviation, and then the signal to the controller, the controller to guide the work of the pusher, the pusher in the By adjusting the material rack, to solve the material offset. General reel feeding frame of the total weight of less than three tons can be used photoelectric correction, more than three tons of the general will recommend using photoelectric hydraulic correction.

　5, photoelectric corrective controller principle is what?
　During the material winding process, the position of the edge or line is detected by the photoelectric sensor to pick up the edge or line position deviation signal. And then the position deviation signal is transmitted to the photoelectricity correction controller to carry out the logical operation, and sends the control signal to the mechanical executing agency, drives the mechanical executing agency, corrects the serpentine deviation when the material runs, guarantees the material straight motion. Optional left and right limit switch to prevent system out of control.

　6, photoelectric correction controller epcsm-600msa how to debug?
　Rectification Controller GD-4A Photoelectricity Correction Controller is an edge position detection device (EPC), which is a system for controlling the position deviation of the thin soft material in the horizontal direction during transmission. It has the functions of automatic detection, automatic tracking, ...

　7, what is the EPC / CPC correction system?
　EPC correction is on the side, to correct the side, CPC is on the corrective, and this is the middle of the baseline correction materials, CPC with very little, only the overall width of the material is not the case back to the use of that volume Materials in some places wide, in some places very narrow, will be used, most of them are using EPC correction system

　8, the work of the optical corrector
　Deviation control system is generally by the controller, sensors and drivers of three units. Optical correction is no exception. The photoelectric sensor detects the displacement of the material and converts it into an electric signal to the controller. The internal PID of the controller is calculated. And then the signal to the drive, the drive signal is driven according to the correction roller.
