Fulici (FritschGmbH) the company is a whole world is banner carbonado earth up machine and systematic manufacturer, install and adjust a function what they chose to apply electric machinery of dc 24V servo to implement a system. This company chose the dc drive controller of WAGO, the working procedure standard of the extraordinary that it abides by in producing a course makes its have extremely high definition, make Fulici had intelligence to change thereby and the systematic control with driving function. Fulici's biscuit carbonadoes the distinct advantage that earths up a machine to have sex of high quality, fail-safe, and all be to face client demand to undertake production. These machines must be endured least 6 days everyday 24 hours uninterrupted the test that run. If systematic component also should satisfy likewise high demand servo electric machinery, servo electric machinery is used at be opposite span of two round screw die (roller clearance) undertake locate and be adjustmented accurately, can produce biscuit semifinished product with appropriate intensity a future life from beginning to end so. Company of the Ci in blessing decides to achieve the energy of this roller clearance and adjust once had tried to use various electric machinery, communicate electric machinery, pace to be waited a moment into electric machinery for example. But still regard best choice as finally dc servo electric machinery. The control 　 of dc servo electric machinery " the fixed position between the roller that electric machinery of use dc drive will come to to have a machine very withstand test. It not only performance is strong, cost is low and wear well " , say of GerhardDanzig of electric branch manager. If change,carbonado earth up means, the roller clearance that needs pair of machines undertakes locating adjustment afresh. But the accuracy that if want,makes the fixed position between roller attains ideal is not easy thing however. Use dc electric machinery has fixed position very simple, driving but definition is not quite high. Previously, the working way of dc machine is with the speed under 1m/s towards the left or move fixed revolution sunwise. Will tell with respect to orientation way, axial fixed position is a the simplest kind, and the fixed position between the high accuracy roller that if want,achieves 3/100mm is by no means easy thing. To locating the time of the process asks without Yan Ke, because carbonado,earth up a product change to often need several minutes, inside this limits, electric machinery has enough time to complete fixed position work. The user chose the dc drive controller of WAGO to serve as a solution. "Our set is worth theoretically now, next dc machine begins to turn automatically proper place, this one real position that electric machinery obtains and at the outset the theoretical value of place set achieves exact tally. Design of this kind of electric machinery is rigorous, had avoided the generation of tone, accordingly the function of electric machinery has reliability very " , electric department manager says Fulici so. Controller of drive of dc of series of 750-636 of 　 of control of intelligent fixed position is controller of fixed position of intelligence of an only channel, contain function of increment position feedback, apply to rated electric current to be the 24V dc electric machinery of 5A, this controller does not rely on type of spot bus line, can regard bus line as module compositive in WAGO-I/O-SYSTEM, passageway of input of 3 24V dc is used at collecting end limit switch and establish signal information beforehand. It still contains port of sensor of an increment encode, computation comes from change at the position send implement signal is worth actually certainly. Fixed position function can be optimized by direction according to demand disconnect beforehand fixed position, the adjustment of clearance of clench the teeth of mature gear is compensated. Two rotational direction of dc motive are the H bridge circuit that contains short circuit protection and temperature monitoring through comes pilot. It is switch direction no matter, soft start / stop, still reduce electric current, can pass wide modulation of arteries and veins (PWM) means comes true. Control of wide modulation of arteries and veins can control the revolution inside a cycle of run or torsion, and the happening that electric current and temperature monitoring function can avoid overload. Debug and diagnose the interfacial implementation that can pass WAGO-I/O-CHECK software tool. This controller can make through a special process principle servo electric machinery overcomes oneself limitation to reach breathtaking definition thereby. From this, the target range that servo electric machinery runs to be set beforehand cuts off the power on time stop to move. The distance that it can have run through measuring electric machinery will identify a target, classics of tolerancepublic errand limits beforehand set, be lasted in the process that achieves a goal monitoring, if deviation can undertake automatically adjustment to its, this makes the control process of electric machinery has plasticity more. This kind of control is equivalent to: Carry out in time for calibration axis when calibration adjusts the circumstance that attrition appears inside limits or pollutes lubricant maintain measure. Adopt beforehand or the means that cuts off electric machinery power source later facilitates in next adjust and the goal achieves easily in calibration process. Process principle of application moves although,rise only number second, but its simple construction can save expenditure however. Contain the effect that brake went to since the gear of function of automatic apply the brake. Hold the cancelled to remove economic energy resources end of torsion, at this moment power source needs very little power only, and this power is met need not change transmit electric machinery directly. The large industry system in Fulici (Impressa project) in altogether used 12 servo electric machinery. "Appearance of dc drive controller is compact, use module type structure, its width is 12mm only, if contactor, tally card and digital amount input a passageway,replaced a lot of important hardware previously " , gerhardDanzig still spoke of this controller be in the advantage of dimensional structure respect. "We need only in all now former the installation space of 20 ％ is enough. "We need only in all now former the installation space of 20 ％ is enough.. CNC Milling CNC Machining
