Q:It was when processing a workpiece, processing spindle stops suddenly (other are normal) a check is, I jump out of the inverter, I can click on a processing, and then processing not long after they happen, (do not open the machine spindle machining will also be the case): Suggest you in the inverter power installed a frequency converter input filter, try it, feel a bit like electromagnetic interference caused by frequency converter mistakenly stop ah.

Q:First of all, I would like to achieve the frequency converter with motor static linear acceleration, high-speed linear deceleration stop processFirst question: I say kind of situation, three paragraph speed start, 0.1hz---> high 30hz-->0.1hzSecond problem: manual speed instruction 1, speed 2, speed 3 instruction instruction I want to use PLC to control three speed motor with three reverse contact dry. I understand speed instruction 1 is switched on (2, 3 connected) transmission section set the frequency with the frequency segment set 0HZ123 AssociationThird questions: manual section, speed command, main frequency and STEP1-STEP7 stage setting frequency, I use PLC analog to the frequency main frequency setting, plus and deceleration, STEP1-7 are set 0, can achieve what I wantInitial contact frequency converter, home pointing: Control the three section speed inversion section, the speed instruction setting surface needs three frequency (M series frequency converter P-17, P-18, P-19) beforehand, which frequency conduction section fast contact line is needed

Q:High-voltage converterGeneral inverterPump frequency converterEngineering frequency converterCould you tell me some frequency converter according to the class?: Specific answer to your question: 1, high voltage inverter: This is based on the input voltage level terms. Generally speaking, 10KV is more than 6KV voltage high voltage frequency converter, 1140V, 3300V in general is medium (some people also called it the high voltage level of 380V, 660V), 480V, commonly called the low-voltage inverter; 2, pump inverter: This is according to the type of application in terms of. Fan pump inverter mainly refers to the frequency converter used to drag fans, pump load, the main feature is light load, simple application.

Q:Can 220V use frequency converter to drive three-phase motor with 380V?: If it is a small power motor can be connected into angular motor then a three-phase inverter output 220 single-phase input 220 will be able to connect, as mentioned above can boost its output voltage frequency is equal to the maximum input voltage, so the 380 can not directly connected with the motor, but if you meet the above conditions can be considered,

Q:Why do you install these things? Our factory has 380220 points. Then we plant in addition to high voltage motor, the other are 380 of the motor, then what's the use of these two things?: What is the difference between inverter energy consumption braking and motor energy consumption braking?

Q:What does "frequency" in household appliances mean?: Microwave frequency with high frequency power to the magnetron necessary boost drive, power supply structure, furnace space more spacious, new microwave oven can adjust power, and choose the best food according to different heating methods, shorten the time, reduce power consumption; lighting, fluorescent lamp with high frequency lighting, can improve the luminous efficiency, energy saving easy, no flicker, dimming, frequency adjustable ballast, compact and lightweight. Frequency conversion technology is bringing a new revolution to all kinds of home appliances, and will bring greater gospel to users. In the future, the frequency conversion technology will develop with the development of power electronic devices, new power conversion topology circuits, filtering and shielding technology. Home solar power generation systems will also add new energy to home appliances.

Q:What are the contents of frequency converter maintenance?: Operators must be familiar with the basic principles of inverter, functional features, with basic knowledge of electrical operations. Before checking and maintaining the frequency converter, the total power supply of the equipment must be cut off, and the inverter Chang lamp will be completely extinguished.

Q:What's the frequency converter for? What does it look like?: The inverter is mainly used in industrial equipment, such as power plants, water plants, water supply equipment, large pumping station, it is basically a cuboid, a digital display control panel; and in the English show types into the universal type, fan pump type, vector control, different types should be used in different working conditions, voltage grade from 220V-10 million volts.

Q:Knowledge, principle and operation method of frequency converter.: The history of the principle of frequency converter:Frequency conversion technology is born with the need of AC motor stepless speed regulation. After 1960s, the power electronic devices through SCR (SCR), GTO (gate turn off thyristor (BJT), bipolar power transistor), MOSFET (metal oxide semiconductor field effect transistor), SIT (static induction transistor), SITH (static induction thyristor (MGT), MOS control MCT (MOS) transistor, thyristor controlled), IGBT (insulated gate bipolar transistor), HVIGBT (high voltage insulated gate bipolar transistor) device to update the development process, to promote the continuous development of power electronics technology (note that because of this, so the inverter is in this background). The beginning of 1970s, PWM VVVF (PWMVVVF) control has aroused great attention. In 1980s, PWM mode optimization, as the core of frequency conversion technology, attracted people's interest and obtained many optimization models, among which the saddle wave PWM model was the best. Since the latter half of the 1980s, the VVVF inverters in developed countries such as the United States, Japan, Germany, Britain and other developed countries have already been put into the market and have been widely used. As to understand the principles of various types of frequency converter, you might as well look at the four changes in the frequency control mode from the simple to the complex.

Q:Which brand of converter is better?: Shanghai Leinuoer recommended! Soft starter and frequency converter products Shanghai Leinuoer company, national key products, Shanghai famous trademark! People's Insurance Company of China quality assurance! Shanghai World Expo Shanghai reyrolle company supporting the project, the Beijing Olympic Games project,
