Servo and technology of Ink> sport control regard machinery of robot of numerical control machine tool, industry and other industry as one of pilot key technologies, in be paid close attention to domestic and internationally generally. In servo and domain of athletic control product, diversification is a bright characteristic all the time, include to arrive from technology of dc servo drive technology of communication servo drive, change complete digitlization, intelligence from imitate, network, arrive from odd axis servo much axis servo, turn bus line product from stand-alone. Well-known, the application of technology of advanced servo sport control and solution promotes machine equipment a of function and class and market competition ability important way just about. Will introduce electromotor of new-style Ac servo at the article / driver technology feature and application, and compositive to system of pilot of network Ink> servo plan makes an analysis. Acink> servo electric machinery / driver technology feature- - the combination that exceeds cabinet appearance and high-powered tall function will be formed from characteristic, system for this, ／ driver combination, position controls electromotor of phyletic, servo join of combination of unit and cable of servo relay unit and norms of Ac servo driver and norms of electric machinery of Ac servo Ink> make a specification, at with Omron (Ink> ohmic dragon) Smartstep2 series is exemple make a specification. High-powered, simplification electromotor of this Ac servo / driver was solved arrive from the design installation and adjust start reach the technical issue that moves to maintain each level. Provided the development platform of whole apparatus especially, make the control of Ink>PLC can pass functional piece to become more simple thereby. And the Fa of the join in the light of yuan of parts of an apparatus or appliance that includes Plc inside and set and process designing (factory Ink> automation) all adds up to kit (Cx-one) , can make this servo arrives from the design safeguard achieved integral administration, see the graph shows red arrowhead 1 times to answer circle a circle, cx-one is to be aimed at include Plc inside the Fa all of the join of parts of an apparatus, set, process designing adds up to kit. All adds up to factory automation kit (Cx-one) , can make this servo arrives from the design safeguard achieved integral administration, graph 1 in the link of the process designing of parameter set ／ that red arrowhead place shows. Used address (functional piece) library makes process designing simpler, and link of monitoring of data editor ／ , use motion to control kit (Cx-drver) the parameter edition that can have servo electric machinery, monitoring and save, its call the police the numerical control unit in section of ／ dimension retaining ring can is opposite the unusual surveillance of driver is simpler. And graph 1 medium Ac servo electromotor / the campaign that driver Smartstep2 series can use Fa all to add up to a tool again controls kit to go to driver spurt dimension. Main feature can be much axis addressly, simply to move because of Ac servo electromotor, because this asks driver is younger, make control ark to install an area to get be cuttinged down considerably thereby. Exceed electric machinery of diminutive Ac servo nowadays / driver is more cabinet, cut down 52 ％ than setting an area with congener product photograph, the economic space that can be control ark makes contribution further. And it and small-sized Plc cooperate, also hope driver can be younger. Especially Ac servo electromotor / the height of driver is 120mm only, can be with small-sized Plc installation between identical conduit, can make conduit span narrow so small change, the space that realizes control ark thereby is greatly economic. Through real time automatic tuning comes set is optimal gain. Bore the weight of namely real time is automatic and harmonious function, thereby but real time is computative the laden inertia of equipment, come as a result according to its automatic set is optimal gain, make adjust thereby become simpler tall function makes the following specification: Can ／ of high speed fixed position is mobile. This is the high rate that its dictate pulse frequency can achieve 500kpps, it is congener before 2 times of the product, can undertake below high speed high accuracy is controlled accordingly, achieved shortened the purpose of intermittent time; Pass controller to be able to receive the feedback pulse that comes from driver, can going up affirm current position, achieved so through feedback pulse surveillant unit fixed position has objective of Chang Zhi of as good as it has the function that maintains 2 kinds of torsion to restrict a cost, insert in extrusion, component in waiting for application, can switching torque is used, achieved a hope to be able to change the end that impetus uses; Will reduce mechanical vibration through getting used to filter. It can detect automatically oscillatory frequency, eliminate vibration, although resonance frequency produces change to also can be tracked automatically in real time, can reduce the rigid and inferior mechanical vibration such as conveyer belt, achieved a hope to be able to reduce the goal of mechanical vibration. It can come to various application switch instruction controls mode, it can be in that is to say the switch between mode of positional control, speed control, torsion control is used. What highlight particularly is to be in press, tension, crowded piece there is outstanding show in waiting for application. Afore-mentioned Ac servo electromotor / the high-powered simplification that the technical feature analysis of driver mirrorred it adequately to install → to adjust the → that start to run → to maintain each level from design → . Driver sort is general input, pulse strings together an input model, its function is as follows: Cent of norms of Ink> power source is Acl00v, Ac200v. And electric machinery capacity divides three-phase of single-phase, single-phase ／ and three-phase again. And cent of interface statement form is strung together for pulse, imitate quantity and the athletic network that high speed servo corresponds. Its control mode to divide the position to control, speed control and torsion are controlled. And control mode switch is divided again for mode switch. Its tuning function has defect wave control, automatic tuning and real time again automatic tuning 3 kinds. And driver function can realize torsion limitation, coder to output in-house set rate. To functional specification its pulse is strung together is a kind of in the light of servo character, it is a kind of way that acts speed and mobile capacity the input through pulse, and torsion control is to adjust rotate the control of force, press in the spare parts, shape, on the utility such as screw close solid very effective; And optimal gain function, because the position dominates the real time when,automatic and harmonious set is automatic set, after because this is in,the movement of definite pattern is inputted repeatedly, can realize appropriate rigid set automatically. Imitate quantity is one kind is aimed at servo, measure speed and mobile volume the way that will input with imitate; And the instruction controls mode switch, can be in control of the position, speed, torsion, the choice controls mode switch 2 kinds to use; Output of its absolute value is after pointing to controller electrify, controller reads the data of absolutely position when taking drive, regain absolutely position in order to come true. Defect wave controls a function but according to oscillatory frequency automatic set filter restrains vibration. When Inc increment output, put through from controller, power source maintains the pattern that origin position begins all the time. Positional control is to show shift arrives target position, after shift is finished, make its stay in the means of a kind of control of target position; And automatic tuning is to show the instruction pattern that electric machinery creates automatically according to driver moves, give laden inertia according to the torsion choose that needs at that time, the gain with automatic appropriate set. Get used to filter but real time is automatic and harmonious, real time is computative the laden inertia of the machine, and according to its automatic set is optimal as a result gain. And the means of a kind of control that speed control is change speed, revolution, rotate in stone of such as burnish, dissolve receives the utility such as speed, deferent speed to go up very effective; Its torsion restricts a function to be able to output the function of torsion through restricting electromotor, this function can restrict ／ in the 1st torsion the switch between limitation of the 2nd torsion is used. Ac servo electromotor / servo of Ac of driver application example is dynamoelectric / driver exceeds servo of small-sized, tall function, and simple, but easy to do high accuracy fixed position. Answer the function of all sorts of utility and rich servo sort, can achieve optimal combination, respect application can wait in ball guide screw, conveyer belt. In using supervisory system of drive of position of electromotor of case communication servo go up because its apply,the communication implementation between a machine and servo driver communicates servo electromotor driver handy with function reliable, wide already application is in numerical control machine tool and industrial position gearing. The driver of new-style communication servo electromotor on the market has the serial communication interface that accords with Rs485 agreement, the computer can use this one interface serial communication comes true between circuit and driver, give out corresponding position to run instruction and speed to run an instruction to driver, dominate servo electric machinery move, the carry linage of electric machinery of seasonable feedback is occupied, offer computer analysis. Good as a result of stability of pilot of this kind of method, precision tall, transmission distance is far, but information of two-way communication control, circuitry is simple, have development perspective very much. Industrial now servo driver configured Rs485 communication interface normally, use this interface to go up through weaving corresponding driver can come true namely the information of a machine and servo driver is interactive. Rs485 serial communication: Industrial Rs485 communication introduces 2 lines twinning transmission means, namely data D+ and data D, , differential of this kind of data transmits means to remove the effect of interference effectively. Additional, rs485 communication is 1: N means, 1 advocate accuse machine (go up a machine) but class reachs 16 machine be accusinged repeatedly (servo driver) . Rs485 communication is regular: Use choice ／ to inquire means, machine be accusinged (servo driver) often be in await lead plane to choose or inquire condition. Servo driver is in bide one's time when condition, accord with the machine be accusinged of number (servo driver) the frame signal that receives leader, after judgement receives signal to be received normally, to frame signal processing. The join of communication: In advocate accuse machine end to change interface for Rs232 ／ Rs485, and end of machine be accusinged is Rs485 communication mouth. In advocate accuse machine and 2 lines are used between machine be accusinged twinning screen cable join, terminal resistance is added in extreme of machine be accusinged. The applied servo of the athletic network that high speed servo corresponds is the important segment in mechanical and electrical products, as the progress of computer technology, communication servo is siding with network to control directional development below the foreground that the course applies extensively. At be necessary to introduce electric machinery of pair of new-style Ac servo / the application of the technology of network of sports of communication of high speed servo of driver makes the introduction. The network servo of the digital campaign controller of the compositive independent character of the network servo that is based on controller of independent number campaign is namely when athletic control, break away from the computer or Ink> labour to accuse the communication of machine to operate control, download control program and the program that should run to athletic controller itself what what take to shine directly put inside. The periphery that has facility sparks signal sparks the program begins to move. Go up a network news report that the computer carries agreement of Ip of supportive Tcp ／ is comfortable distribute card (100m) the support that wins pair of aether net bus line, be in charge of pair of whole systems move to have surveillance government with working status. Go up a computation after the task that finish plans, by tripartite software the user that finish uses program development, the program statement that adopts aether net to will be generated according to agreement of Tcp ／ Ip conveys Ink> is embedded controller of much axis motion. The position with ceaseless newer generation commands controller (athletic curve) , through driver is being sent below Ink> spot bus line, eaves pulse signal counts translate into after bus line node explains an instruction, in order to control communication servo electromotor, the fixed position that finish. In all of a many shafting, a controller can control drive of many electric machinery. Servo electromotor is main executive part, complete specific action. Athletic controller can use controller of motion of Fqm1-mm22 much axis, these controller use usable also Mc260 industrial appropriative 32, the technology of newest small processing of 120hhz ～ 150hhz, shirt-sleeve and newest control theory and its network control a technology, can choose different controller controallable 1, 24 axes. The output of imitate quantity voltage that can use 10v of 0 ～ ± and coder feedback form full closed-loop control, will control servo electromotor. Also can control a pace to enter electromotor, ink> transducer, pneumatic, hydraulic pressure servo, or these a few kinds random is united in wedlock. Week of epilogue numerous place if, numerical control machine tool and industrial automation cannot leave servo electric machinery / the intelligence of driver power source is changed, be in network times now especially, change besides the intelligence of dynamical plant outside, still require network. And electromotor of servo of afore-mentioned new-style Ac / driver technology feature and applied introduction, idealer can solved servo electromotor / driver from design → - installation → adjusts the → that start to run → to safeguard numerous the intelligence of each phase problem is changed, the project that it is industrial automation designs staff a kind of better choice, the research and development that also is industrial automation system widened design train of thought.
