1 system program pursues program of system of Nextpage of block diagram of 2 systems control refers to a system to control block diagram (graph 2) . Equipment main body chooses a stage to amount to Electromechanical series (following watches) 2.

2 systems analysis close put a craft to ask constant tension is controlled. Of tension give through tensional controller. Principle of tensional controller pilot is receive the linear velocity that coil to calculate through detecting a diameter, load turns D/2 of the ＊ that be apart from =F (F is set tension, d is coil currently diameter) , because this is become set tensional size, because coil currently,diameter already was informed through computation, laden torsion is so OK numerate. Tensional controller can output the imitate of 0 ～ 10V of the standard to measure signal, the rated torsion of corresponding asynchronous electric machinery. So we measure signal to receive transducer with this imitate, choice torsion is given. Such is in whole in controlling the dynamic process that coil, what can assure tension is constant. Below transducer torsion mode, undertake limitative to speed. In tension control mode falls, no matter the restriction that dc machine, alternating current machine or servo electric machinery want to have rate, turn when what electric machinery arises otherwise be apart from when can overcome laden torsion and moving, can produce rotational acceleration, and the addition that makes rotate speed ceaseless, rise finally fast to highest fast, it is so called flying car. If pursue 2 in be shown, close putting the rate that coil is the imitate that passes transducer of series of main shaft B the quantity outputs AFM and undertake definitive. Get on the transducer of series of main shaft B namely 3-05 (imitate signal outputs a choice) parameter set is 03 (frequency instruction is outputted) , if pursue,3 are shown. Receive this signal respectively receive the imitate that puts a transducer to measure input port to go up, give the set signal with upper limit frequency as frequency. 0 fast tension control a demand. Should close put when coiling to move with 0Hz, there is certain tensional output on the take-off of electric machinery, and adjustable. This requirement basically is to prevent to should close put a movement in the center jockey, can assure to close when restart put dish of head that coil won't come loose. In this control system, can achieve a requirement through adjusting the initiative tension set on tensional controller. 2.

3 minutes the principle designs a machine constant tension 1) principle of constant tension pilot. Essence of pilot of tension of the constant in putting lick Cheng to closing is need the variation that knows load is carrying diameter coils in profession, because coil the change of diameter, bring about move ladenly to maintain, the output torsion that needs electric machinery should follow to coil of diameter change and change. To with V series transducer character, because can make torsion control, because this can be finished,accept the control of a constant tension. V series transducer offerred 3 imitate to measure input port, AUI, AVI, ACI. Mouth of input of quantity of these 3 imitate can be defined for a variety of functions, accordingly, OK and optional give as torsion all the way, serve as speed limit all the way additionally. Corresponding transducer of 0 ～ 10V outputs 0 ～ electric machinery rated torsion, pass the voltage that adjusts 0 ～ 10V to be able to finish the control of constant tension so. And to distributing a machine, computation coils the part of diameter is to pass tensional controller to come calculative, come true of course with PLC framework also do not have a problem. That is to say, can pass in tension of the set on man-machine or text, through PLC computation coils diameter, t=F ＊ D/2, so can the torsion size that electric machinery of cipher out need outputs, it is OK that the torsion that receives V series transducer through imitate capacity output gives end. 2) computation of synchronous rotate speed. Because we know transducer job is when low frequency, the character that communicates asynchronous electric machinery is bad, low and activation torsion is nonlinear in controlling the whole process that coil accordingly, should avoid to receive an electric machinery job to be under 2HZ as far as possible. Because this accepts a restriction that electric machinery has a lowermost rate. To 4 extremely rotate speed calculates its synchronism as follows electric machinery: N1=60f1/p=>n1=1500r/min=>2HZ/50HZ=N/1500=>n=60rpm/min (F1- is for rated frequency, P- extremely synchronous rotate speed of logarithm, N1- ) Nextpage3) speed limit moves. When obtaining the biggest means, can seek a minimum that in controlling a whole process, moves fast: N/i=>Vmin=3 of ＊ of D of V= π ＊ .

When 12m/min tension is controlled, want to undertake limitative to speed, can appear otherwise flying car, because this wants speed limit,move. 4) the computation of tension and torsion.

Of parameter of electric machinery of 1V series transducer rectify oneself calm 1) restore all parameter of driver to leave factory value. 2) electric machinery axis and laden come away. 3) electric machinery 01-01 of parameter of rated frequency of rated voltage 01-02, electric machinery, write numerical value correctly respectively. 4) it is parameter 05-00 set 1, press the command of KeypadRUN next, what carry out electric machinery instantly right now is automatic whole calm.

Vector of closed circuit of 2V series transducer tries carry to be run mode set face plate to start all right, frequency gives means for face plate. Run mode becomes frequency set 10Hz for V/FPG, move next, observe whether transducer can sign up for PG to call the police, if sign up for PG to call the police, it is 10-01 set 1 (it is so 0, conversely set is 0) , cut off the power next new electrify. Press moving button again, ensure transducer calls the police no longer, press Mode key at the same time, switch buy shows running frequency, whether does observation running frequency issue wave motion on 10Hz, ensure closed circuit vector moves debug finish. 3.

Assure tensional pilot limits cannot too small, general tension limits is when hundreds of Newton are bigger even, do tension to control be the need that can satisfy a client with transducer. If tensional scope is too little, it is to cannot use transducer to have tensional pilot. Because low turn be apart from, when small load, the function of V series transducer still is first-rate, will turn be apart from tone to arrive special hour, electric machinery movement is not very smooth. Still want to understand the requirement of clear client when making similar application so, lest cannot achieve the client's requirement. CNC Milling CNC Machining
