East can the servo application on machine tool of horizontal numerical control

One, summarize numerical control (Numerical Control, abbreviation NC) is 20 centuries the technology of a kind of automata that 50 time development rises, it is to use digital signal to have pilot to process of the motion of the machine tool and treatment a kind of method. Computer technology is introduced in numerical control technology, call CNC(Computer Numerical Control) , CNC is had flexible good, function strong, dependability tall, economy is good and realize the characteristic such as Electromechanical unifinication easily, make numerical control technology completed a flight in qualitative respect. 2, machine tool of numerical control of horizontal of craft brief introduction by CNC controller, 4 parts comprise the frame of ark of servo drive and electric machinery, electric equipment and numerical control machine tool. Its job principle is: Pass the software of special process designing of the configuration inside CNC, the contrail what machine a spare parts comes out with the means expression of coordinate, change these message into can make the contains power signal of drive servo electric machinery (pulse is strung together) , control servo electric machinery drives corresponding axis to achieve athletic orbit. In the meantime, deserve to have numerical control lathe tool on tool carrier, through pressing treatment material configures corresponding cutting tool character, to securing the treatment on main shaft material undertakes cutting, can process a corresponding work. 3, machine tool of numerical control of equipment composition horizontal by CNC system, servo drive reachs electric machinery, 4 parts comprise electric equipment ark and machine tool lathe bed. CNC system: Basically finish carry out the program inside its memory to realize numerical control function, deserve to have interface circuit and servo actuating device only maneuver calculates engine system, him system the contains power signal that calculative information changes into drive servo electric machinery (pulse is strung together) , each axis makes machine tool of control numerical control X, y, the method taking a knife of Z3 axis, press automatically given machine program treatment gives work. So, system of computerized numerical control is a kind of digital control system that includes the computer inside. 4, control line (CN2) hookup and servo parameter setting 1) control line (CN2) hookup Nextpage2) parameter installs a specification: PA4=0(controls means option, 0: The position controls) ; Model of PA9=16(electric machinery chooses, different electric machinery this parameter is different) ; Gain of PA11=3500(position annulus, limits 500, 8000) ; PA27=0/1(pulse input is taken logically instead, can use at changing) of electric machinery direction; PA31(inputs instruction pulse) of times frequency element; PA32(inputs instruction pulse) of times frequency denominator; Note: Electronic gear compares =PA31/PA32==Ppulse / P among them Ppulse: Electric machinery every turn pulse number, the pulse that points to what component of feedback of circuit electric machinery feedbacks to electric machinery rotates is counted (pulse / circle) . Be like the increment type coder of 2500 lines, its feedback to be 2500 × 4=10000 to the pulse number of driver; P: Point to want what circuit servo place needs to receive to make electric machinery rotates go up a number of machine instruction pulse (pulse / circle) ; 5, debug with the note 1) debug measure: Receive line of power of good electric machinery A, correctly (U, V, W) , coder line (CN3) , power supply cord (L1, L2, R, S, T) , receive fine control line (CN2) ; B, low speed runs electric machinery, see electric machinery way correct (but through adjusting PPA27 parameter changes electric machinery way) ; The electronic gear of driver of C, good according to asking to install servo is compared (PA31/PA32) ; D, after completing afore-mentioned step, running electric machinery, it is normal to see electric machinery sound, electric machinery tigidity is contented, and answer time; (can pass adjust: PA11 of positional annulus parameter, PA12, PA13; PA38 of parameter of annulus of electric current of PA14 of speed annulus parameter, PA15; , PA41) . E, after adjusting, a sample sees turning whether satisfy a requirement, d measure can repeat when sample is bad, the sample that gives till turning satisfies a requirement. 2) note: A, receive dynamical line (U, V, W) when, must one to one correspondence receive terminal of U, V, W to go up. Cannot change electric machinery way through changing order of photograph of U, V, W, but through adjusting parameter should change electric machinery direction. B, receive control line (CN2) when, must have line of one termination screen. Avert the outside interference to controlling signal. C, wiring must reasonable, hand in direct current source to want strict departure, control line should use line of force with electric machinery, power supply cord parts strictly. 3) result: Compare the lathe before the client, with servo not only get rising greatly on speed, and also rise than before in fixed position precision a lot of, before the sound of electric machinery also is compared small much, make the client achieves the biggest satisfaction to spend. 6, breakdown and eliminate a method 1) breakdown: Go up a machine run to signal electric machinery flew, driver appears 09 call the police; Eliminate a method; Line of power of examination electric machinery (U, V, W) whether does appearance sequence receive a fault, examine model of driver PA9(electric machinery to choose) whether to install correct. 2) breakdown: Appear 27 call the police eliminate a method: Examine electric machinery coder line (CN3) whether to loosen. After been secure, trying. 3) breakdown: Go up a machine deliver pulse, electric machinery does not move eliminate a method: Examine control line (CN2) medium line is wrong, examine servo driver PA64 to look to whether be installed correct, driver interior makes can (PA64=64) , go up a machine make can (PA64=0) . 7, summed up machine tool of this numerical control to be united in wedlock adequately east can the response of servo EPS2 series is fast, fixed position is accurate, entire calm time is short, move smooth. Make the client achieves the biggest satisfaction to spend thereby, not only the yield that raises a client, quality, and save labour cost for the client. This equipment revealed Zhejiang adequately to the client east can the technical capability of limited company of science and technology, make at the same time lathe manufacturer in the market the competition that sexual price compares increases greatly.
