An Bangxin A11 and E11 transducer cut the application on machine in cent

E11 of article introduction An Bangxin is based on the summary the applied program that the transducer of vector frequency conversion that does not have speed sensor cuts aircraft equipment to go up in cent and the problem that the attention answers when debugging, because it has good torsion character and maintenance-free property, be used already increasingly at pack and pressworking cent cuts enterprise keyword machine transducer tension controls 1 preface in last few years the papermaking course of study of our country is reached presswork the industry that pack obtained flying development, be faced with unprecedented tremendous opportunity, but the equipment with advanced to the world photograph, also facing enormous challenge. The productivity that produces equipment is very powerful, but our product is in basically in low end the market. Main reason is the limitation of technical condition. It is at present to, many cent is cut magnetic particle brake still is used to undertake tension is controlled closing putting coiling on machine, restricted the traversal speed of equipment, also wasted the sources of energy, and the reason of the service life as a result of magnetic particle itself, created the situation with higher fault rate. Install state to believe the G11 transducer that the company rolls out, can undertake constant tension is controlled, and can control tensional taper, assure to receive each form after coiling even, and huge raised cent to cut the traversal speed of machine. Cut machine introduction cent 2 minutes machine it is the mechanical facility that cuts wide cut paper or filmy cent one kind material of many narrow cut, commonly used reach at papermaking machinery presswork package machine. If the graph is shown 1 times,cent cuts the simple and easy sketch map of machine. The graph cuts the tradition of machine 1 minute to dominate program is to use a big electric machinery to come drive closes put the axis that coil, closing put add on reel have magnetic particle clutch, through adjusting the electric current of magnetic particle clutch controls the obstruction that its produce, will command the pulling force of material surface. Magnetic particle clutch and brake are a kind of special automation carries out component, it is to pass fill to deliver torque at the magnetic particle of working space, change excitation electric current can change the magnetic position of magnetic particle, adjust then delivered torque. Can use at from the 0 stepless speed regulation that begin synchronous career, apply to high speed Duan Wei to move the timing system of the small-power in reaching. Still use at using to adjust voltaic method adjusts torsion carries constant open a book with assuring the tension in winding process or answer roll tension controls a system. Its main characteristic is magnetic particle clutch regards an obstruction as device, pass systematic control, will output a volts d.c. , control the obstruction that magnetic particle clutch produces. Main advantage is its are passive device, can command lesser pulling force. Its main drawback is speed cannot tall, when high speed moves easy cause magnetic particle high speed to grind, generation high temperature, cause magnetic particle clutch to give out heat shorten then its life. Nextpage3G11 changes implement implement the control block diagram on machine cuts in cent: Plan explains: Drive of transducer of E11 of use An Bangxin presses roller, control cent cuts the traversal speed of machine, it can work in open loop vector means. Advocate speed can be adjusted commonly with potentiometer. AO1 port serves as the output of running frequency, as put a transducer, on, next linear velocity that receive a transducer are given. Put a transducer to reach receive a transducer to want to use A11 transducer, a11 transducer is one kind can realize tensional pilot transducer, can pass the computation of transducer interior, obtain the torsion of a need, through controlling the output of transducer torsion gains constant tension control. Graph the 5% above that the 2 torsion that control transducer because of vector control precision to be rated torsion, spend a hour when pilot pulling force so, when coiling for nothing transducer should output small torsion, more difficult. Parameter configures a circumstance: Advocate drive transducer (E11) : (control without speed sensor vector) (terminal commands) (AI1 is inputted) (hind class transducer input and frequency of drive transducer input are divided) other parameter all acquiesces to leave factory value. Debug circumstance specification: When using G11 transducer to make cent cut engine control, suggest use electric machinery procrastinates to change the way of main shaft and need not install decelerate device directly. Main reason is the output torsion that the quantity controls to be transducer finally when transducer commands pulling force, torsion is tension and roll the product of diameter, when coiling for nothing, output torsion is the smallest. If decrease speed ratio to be N, convert is torsion to the torsion on transducer / N, if be less than electric machinery 5% of rated torsion, criterion pilot is not quite accurate. When debug, it is normal to will receive the way of closed circuit vector that puts 3 transducers that coil to debug above all, do not have a law to finish follow-up torsion control otherwise. The process is here medium, most the problem that often encounters is coder signal was not inputted, rotate direction of coder A, B is received instead, input of coder pulse number is incorrect. The expressional form of these a few kinds of problems basically is traversal speed and input speed deviation bigger or electric machinery low speed wriggles and moving electric current and actual sky carry electric current to differ bigger. The transducer in putting a control just provides a retrorse taut power actually, demand of its control precision is not so high. Debug relatively simple. About 0 fast when retrorse and taut, a11 transducer can offer two kinds of alternatives, one is to allow retrorse and taut function, behaving a form is to be in 0 fast Shi Reyun commands all right did not remove, criterion transducer is controallable electric machinery all the time material taut, avoid to just began the velocity shock that when moving, slacken as a result of material and creates, draw material. Additionally one kind chooses to be tightened up reversely to do not allow, in 0 fast travel command did not remove Shi Reyun, criterion transducer is outputted without pitching moment. Material may slacken, but the flying car condition when can avoiding to expect. Receive a transducer to work to control mode in tension, in adding decelerate process, need offers additional torsion to take systematic moment of inertia with Yu Ke. If do not add compensation, can appear the tension in receiving lick Cheng slants the tension in little slowdown process slants big phenomenon. If start when occurrence tension decrescent, increase systematic inertia to compensate coefficient. Grind compensation basically is to overcome the friction that exists as a result of the system in whole moving process the influence to tension, can grind through adjusting compensation coefficient will finish. If tension of the material when moving normally is less than set tension, compensate attrition coefficient to increase. Additionally need compensatory is the moment of inertia that place of the stuff on reel produces, pass the density of set material and width, transducer is calculable the moment of inertia that gives current data. When debugging taper of appropriate set tension, can control the curly quality of material, outside avoiding, tighten inside loose circumstance happens. Diameter coils below a lot of circumstances obtaining is all crosses a line fast numeration will obtain, a direct element that diameter is computational output torsion, correct set is the so biggest linear velocity is special key. What when debugging, can show through transducer of test and verify is current a diameter and coil actually diameter, will judge place to set the biggest linear velocity correct. If show coil currently diameter is more than coil actually diameter, the biggest linear velocity that shows place is set slants big. Pass a few compensation of set above, can change the effect that systematic inertia reduces to adding effectively. The tension with appropriate set, can achieve those who had compared to accept a control. Because 4 last words control cent to cut with transducer of machine receive the weak point that put a control to overcome magnetic particle solid to have, make the control that high speed cent cuts became reality, and the dependability that improved facility greatly, go up from cost and did not increase too much, so more and more clients begin to use transducer to realize cent to cut engine control.
