Limited company of Yunnan CY group (factory of former Yunnan machine tool) only then built 1961, it is business of mainstay of stress of Chinese machinist industry, state-owned accuse a machinery to create large company, have self-supporting imports and exports to counterpoise, it is China western the lathe manufactory with area the largest scale, year produce various lathe 3500 above. Come 10 years the product holds 2/3 export all the time, the product sells as far as to 77 countries such as North America, Europe, Australia, south Africa, North Africa, middle east and southeast Asia and area, export 7 years continuously achieve collect maintain 1000 ～ 13 million dollar, hold lead position all the time in outstanding achievement of exit of industry of Chinese machine tool. There is complete cent to sell system of the after service before the carry out such as support of network and machine parts or tools kept in reserve, spare parts, technology on home and international market. Product of this company dominant is nicety of lathe of CY series center lathe, numerical control, high speed lathe, big aperture lathe, copy lathe. Developed lathe of numerical control of complete function of whole set of #20 ～ #20mm energetically in last few years, its are main the product is judged to be product of high grade famous brand, numerical control machine tool is judged to be countrywide user satisfaction to spend the first. The product already formed 5 kinds big, 234 kinds of norms, market opportunity, report, fluid, cheap and tall, medium, compatible, the product lineup with all ready norms, the product applies to a variety of industry need such as mechanical, car, petrifaction, enginery, spin, shipping, aviation, spaceflight extensively. The power of electric machinery of machine tool main shaft that this company produces from 5.

5KW, 15KW differs, electric machinery is 4 extremely frequency conversion electric machinery, electric machinery of all main shaft all uses frequency control to replace the gear gear-box of primary vintage machine tool, transducer can accomplish stepless speed regulation inside the timing scope of the machine tool, original transmission case of far outclass of its timing scope, the object random that can machine according to place cutting adjusts main shaft rotate speed, now with 7.

5KW is a row, to its timing process undertakes demonstrative. From on the graph can see, rotate speed of its main shaft turns from 0-3000, the output power of 1000r/min the following electric machinery drops as the fall of rotate speed, 1000-3000r/min is constant power output, 4500r/min of electric machinery rotate speed, according to N=60f of formula of electric machinery rotate speed (1-s) / 2p, place choosing electric machinery is 4 extremely electric machinery, turn in oversight below the circumstance of poor rate S, the highest frequency that requirement transducer outputs amounts to 150HZ. Transducer is in 50HZ, constant power timing is between 150HZ, in 50HZ the output power of the following electric machinery becomes linear to reduce. The general transducer on the market can satisfy this timing basically to ask now, the transducer that Dan Yun machine produces basically is given priority to with exit, face global market, sex of the reliability that needs to consider product of form a complete set so, brand, wait for factor with international consequence, choose the United States through inspecting a decision for long the PowerFlex40 transducer that company of the AB below Wei Erqi produces Luoke. PowerFlex40 transducer designs close achieve, economic space, offerred powerful electric machinery speed to control a function to the user, such design is to be OEM of contented whole world and final user to be mixed to flexibility, economic space use convenient requirement. This transducer has 150% overload to be able to last 60s can last with 200% overload the overload of 3s protects ability, its PWM frequency is adjustable to 16kHz, assured the low noise when electric machinery moves. As a result of machine tool main shaft add decelerate more frequent and increase slowdown time short, resistor of transducer interior apply the brake wastes the energy that produces in process of apply the brake hard, reason installed resistor of exterior apply the brake, its resistance is 60 Europe, 1 kilowatt, transducer itself already inside buy apply the brake is unit. Corresponding parameter series writes parameter of electric machinery famous brand before transducer moves, setting transducer is control of open loop vector, exterior resistor apply the brake, the highest frequency 200HZ that move, the setting adds slowdown time to be 1 second, transducer stops means to set stop for brae, the investment after parameter setting is finished moves, but in the breakdown that code often malfunctions to be F5 in staying machine course, this breakdown prohibits to add decelerate, shed bus voltage freeboard continuously, consult the specification sets slowdown time for 3 seconds this breakdown code continues to appear, analyse resistance of exterior apply the brake and power through computation demand of enough competency apply the brake, read transducer manual again carefully, the of short duration that discovers resistor of A082 parameter trends carries rate for 5% , this parameter is to protect the acquiescent value of overheat of resistor of transducer interior apply the brake, because had used resistor of exterior apply the brake, can be worth this enlarge so, set its for 20% , breakdown phenomenon is absent happen, it is slowdown time setting 1 second again, this breakdown code is not recurrent also, when transducer the job increases in noise of the electric machinery when 60HZ-90HZ, and companion has machinery to shake, when be more than 90HZ, this phenomenon disappears. Because,preliminary analysis may be this frequency paragraph with electric machinery organic instrument is mixed electric those who go up do not match, consult again manual, discover A127 electric machinery rectifies parameter to did not undertake installing surely oneself, come away of electric machinery load, undertake electric machinery is rectified oneself calm, this process transducer can be read automatically take electric machinery parameter, in order to build with electric machinery most the control model that match, reduce greatly through rectifying the electric machinery after deciding to run noise oneself, to make the output weaveform of transducer more flowing, carrier wave frequency the setting is 6K (acquiesce is 4K, highest for 16K) , electric accident travel is very right now smooth, noise disappears basically, cloud engine is very satisfactory to this. Preparation is in the following this transducer is chosen entirely in using, in order to enhance international competition ability. Accordingly, from the point of above circumstance, a few parameter that the specific requirement that notices a client and transducer want only in extending a process are installed, PF40 transducer is in machine tool industry can be competent completely.
