003 be based on accident of PCL servo Zuo to move control system to design need to consider a lot of professional content, the working principle that needs pair of PLC and servo electric machinery especially has a clear understanding and knowledge, undertake planning from whole on this foundation, make clear the function of each module, undertake specific aim is designed, those who assure to design the job is successful and efficient finish. The motion of servo electric machinery that the device introduction that 1 design uses is based on PLC to assure controls a system to design successful implementation of the job, place should be made clear to use device and property in the design, the article makes SGDV-2R8A01A of in order to is the servo electric machinery of drive module, patulous module of the PLC that uses moxa silent to lay EC10 series and A/D, I/O, use interface of the man-machine that believe nimble. Among them if relevant parameter of servo electric machinery, drive and PLC expresses 1 to show: The technology of PLC of implementation have the aid of of means of control of 2 electric machinery realizes the control that moves to servo electric machinery, basically measure point of view from impulse of arteries and veins, imitate, realize contrapuntal buy and the control to electric machinery speed, control speed to need two proportionate imitate to measure output among them, use PLC to be configured to D/A module namely, realize the changeover of data and processing, corresponding imitate voltage the value outputs the input in the servo module to electric machinery, in order to match rate, want to know the positional news of electric machinery, can pass the pulse information in analysing servo module to obtain, the pulse information that is about to obtain realizes what cease to positional letter to change can. Nevertheless, although means of this kind of control can come true, but the I/O module that needs moster capacity. Control photograph comparing with speed, match speed and fixed position implementation relatively simple: After servo module receives instruction pulse information, undertake be changinged relevantly, to the output of voltage electric current the circumstance undertakes controlling, realize the drive to electric machinery. Meanwhile, adopt frequency of pulse of servo drive module and measure, controallable electric machinery speed and rotate quantity. Have the position to dominate instruction market considering PLC, because this does not receive positional feedback, also can realize the computation of pair of pulse amounts, circle line significance and the foundation that frequency concerns to be handled correctly to go up to electric machinery in PLC namely, carry pulse signal send, promote double opportunity between each other cooperate each other, the implementation difficulty of this one process is lesser, when trying to control to complete closed circuit, the pulse that need carries to electric machinery has count, can master electric machinery to carry instruction of whether very good the pulse that finish well so. Additional, because program processing stays proper time, need to take specific aim relevant measure. The article applies the position to control means to control a system to undertake designing to motion of servo electric machinery. Implementation of pilot of 3 odd double electric machinery uses servo of coil winding machine, control condition of movement of servo electric machinery and state neatly, associated control is relevant parameter, the control that is double electric machinery lays a foundation. Anyhow, when the design controls module, ensure to odd electric machinery the control of all sorts of functions is the key that whole design works. 3.

The implementation of pilot of control odd electric machinery of 1 odd electric machinery relies on PLC position to control an instruction, the PLC of article application has PLSV instruction, DRVI instruction, DRVA statement, among them PLSV instruction runs an instruction for gearshift, the speed that dictates as the change of time lies in constant change, control implementation way is relatively quick, cannot realize fixed position nevertheless. DRVI dominates opposite niche, when to fixed position the operation is carried out, once speed is worth change,need to involve the statement go into effect of ability of a week period. DRVA dominates absolutely niche, electric machinery speed does not produce change during fixed position, after the fixed position that finish is operated, electric machinery stops, wait to issue a statement. When this system is designed, advocate accuse to run an instruction to use PLSV, to assure advocate the success that accuses to move, DRVI, DRVA basically is used at be opposite advocate those who accuse to move is auxiliary, fall in suspensive condition, undertake to electric machinery fine tuning and relevant fixed position are operated. On the foundation of detailed to controlling division of labor knowledge, build control program. On one hand, the control that move comes true. Namely, start the program, press the pushbutton that start implementation winds the fixed position operation of the dot to rising, suspend its after that; Undertake pressing again operating to running pushbutton, electric machinery is rising circle a dot to what make a round trip between terminus to go there and back; Should suspend pushbutton by short on time, electric machinery phase out moves; Make electric machinery new move, need to press moving pushbutton again; Be in when electric machinery when suspending status, lengthen press the time that suspends pushbutton, electric machinery revert, return afresh at 0 o'clock. On the other hand, adjust an operation. Use two the dot uses button, can order the electric machinery that uses control to be in suspensive condition to fall, make electric machinery finish retrorse with moving an operation to the dot. When writing program of PLC echelon image, number of pulse of number of the speed during using the speed, speed during moving, fixed position to the dot, terminal pulse, start undertakes beforehand set, the sheet in combining servo module encircles pulse number, gear ratio, the rotate speed case that can leave in different pattern to electric machinery. Additional, SD80 of register of need have the aid of undertakes inverting, below action of port of this register pulse, after accepting relevant statement, realize the computation computation that counts to pulse, contrast after that start and terminal pulse amount, make relevant judgement. When SD80 exceeds border, compare an instruction to be aroused, undertake inverting is operated, take turn over PLSV pulse operand, finish change direction (if pursue,1 shows inverting flow) . When dominating odd electric machinery, need to master PLC relevant knowledge adroitly, use all sorts of fixed position statements adroitly. In the meantime, pay attention to a concept to design the consideration of train of thought, had done the thorough research that runs technological process to electric machinery, for double electric machinery control and the implementation that debug the job make good bedding. 3.

The implementation of pilot of control double electric machinery of 2 pairs of electric machinery needs to increase I/O amount, the PLC that the article uses advocate the interface amount that module has cannot satisfy relevant requirement, because this need uses patulous module. The article uses knob type rheostat, the adjustment that passes bit of voltage realizes the control of pair of electric machinery traversal speed. At the same time advocate module cannot handle imitate volume, need to use A/D to change module to undertake changing. The modulus of voltage have the aid of that gets on rheostat so realizes what measure to the number to change, PLC handles digital amount to undertake relevant output. Nevertheless positional control mode falls can have transition to retrorse D/A. The control complexity when dominating double electric machinery at the same time is met be able to rise, need to solve two groups of electric machinery to run the associated sex of condition and speed especially, it is those who achieve pair of rate to match, need designs positional system. To ensure speed matchs successful implementation of the function, should design among them an electric machinery gives priority to electric machinery, a/D changes data immediate effect at this advocate dominate electric machinery, what move to assure two groups of electric machinery is synchronous, need to use PLC to undertake monitoring to the moving information of driven electric machinery. When undertaking designing to running a program, need to analyse the electric machinery that discharge a line and the transport guild regulations from the electric machinery that wind a string deep law, match a function to lay a foundation for better implementation. Do not spend career of two electric machinery match suffer line broad effect, the electric machinery that wind a string matchs with what discharge speed of line electric machinery should satisfy: Set line is broad / rotate speed of electric machinery of line of platoon of = of filar lever pitch / rotate speed of the electric machinery that wind a string. When contrapuntal place system undertakes designing, answer to make dominant with discharging line electric machinery to become, meanwhile, use the program that sets in PLC, undertake monitoring to the positional register of this electric machinery, pay attention to the design of absolutely place system. Additional, those who need an attention is, circle turn number for computation, those who be located in the register on the electric machinery that wind a string to be able to have a number is cumulative. Travel system has double report accident to move normally reach turn to a function while, still can control successive, weak condition through the operation, make moving nimbleness of coil winding machine gets rising apparently. Weak condition / successive pilot comes true: Weak condition is installed when inverting is operated / successive control switch, the system when switch was not enabled lies in continuous motion line of business, undertake the operation still won't cause an effect to moving changing. switch open hind, undertake inverting is operated, department Jian stops to move, press moving key system restores to running state. When coil winding machine undertakes moving alone, when the consolidate layer that needs certain to coil area undertakes strengthening operating, should apply the brake discharges route aircraft, be in its suspensive condition, its allow to wind a string in booked position, a few switch can be installed when choosing a function to come true especially. When the hand moves pair of moving direction to undertake controlling, below certain condition, need the border that screen establishs beforehand, when the exercise winding a string that should discharge line electric machinery especially lies outside wide cut, will cannot undertake to its automatic inverting is operated, need undertakes according to armrest right / the control that towards the left runs, with undertaking handling to a few movements that wind a string. According to afore-mentioned train of thought, to double electric machinery moving module undertakes controlling, specific flow shows 2 times like the graph: Of 4 systems start with when stopping to configure the PLC of EC10 series, can switch on the mobile phone to what the input nods mode undertakes configuration, switch on the mobile phone to what the input nods mode undertakes choosing, decide in X0 ～ X7 one regards as the switch of the PLC that start. When undertaking programming, can be setting of the switch that start X7. After PLC and power source put through, do not press when X7, PLC is in bide one's time below condition, should press when X7, when PLC discovers the existence OFF change to ON into line scanning to X0, begin to run PLC program. When the STOP in activation system dictates, PLC program suspends moving. The system stops to move in the program to have two kinds of show: The flow that wind a string ends, the system stops. During winding a string, stop because of interrupting, of course the system is urgent latter should be belonged to when stopping. To ensure latter inactive dependability, jump to OFF by ON when X7 the program when changing is sparked to stop, undertake appropriate delay time saves data information, for next time the program moves make bedding. Additional, when designing a system, x7 designs the switch that can control spur track to be able to flow, when X7 is OFF, the instruction in the program all cannot move, the breakdown occurence rate that the program runs was lowered on certain level. It is the problem that in discovering this system is designed in time, appears, after waiting for each module design to finish, need to undertake debugging handling, will look through debugging a result to this system, the error between function of coil winding machine and academic convert value is minor, processing of a few detail in analysing a reason to may write a process because of the program is couldn't get, or the effect that suffers hardware electromagnetism compatibility, after needing to undertaking serious analysis, undertake be optimizinged appropriately with processing. 5 epilogue are based on motion of PLC servo electromotor to control systematic design to use more professional knowledge, need to be on the foundation that studies design requirement seriously, strengthen what design link each to discuss, begin smoothly for what the design works lay a foundation. The article reachs through research the following conclusion: (1) the article designs be based on motion of PLC servo electromotor to control a system, applied hardware basically has servo electric machinery, corresponding drive module, PLC and relevant patulous module to wait; (2) the base that behavior of device understands adequately is being used to place in designing a process, design working key clearly, the article is opposite especially of control of the control means of servo electric machinery, odd double electric machinery and system start with stop to undertake the key is discussed; (3) undertake debugging moving on the basis that completing to each module design, the research that discovers need of a few small issues is farther and optimize, taking one with another, the motion of servo electric machinery of the design controls a system to satisfy a design basically to ask, and can begin for what a few designs will work henceforth provide reference.
