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): It should be a frequency converter. Right now, look at the frequency converter output frequency settings, tune, and suggest the next election wide output frequency converter, or simply PLC

Q:What is the main harmonic produced by a transducer? How about the degree?: To reduce the influence of harmonics, various measures can be taken, but for the inverter, the main circuit is to install an AC reactor.The input side of the inverter generates the harmonic mechanism: for the inverter, as long as there is a rectifier circuit on the power supply side, it will produce harmonics caused by nonlinearity. Based on the three-phase bridge rectifier circuit for example, AC grid voltage for a sine wave, square wave AC input current waveform, the waveform, according to Fourier series can be decomposed into fundamental and harmonics, usually containing 6m + 1 (m=1,2) harmonics, the harmonics in power grid. A single fundamental wave, combined with several harmonic waves, is called an abnormal wave

Q:How can I control the frequency converter with a computer?: The use of single-chip to control the inverter can choose the last two kinds of methods, the use of communication control, the utility model has the advantages of full control function, suitable for inverter through the level conversion circuit form of communication (RS484/RS232/CAN), you can communicate with the inverter hardware is simple, the number of connections between the two less convenient connection. The disadvantage is that we need to understand the communication protocol of frequency converter to control programming, and the software design is complicated. The inverter communication interface and communication protocol of different brands are different, there is no uniform standard, only for a converter for development, narrowing the selection range of the frequency converter varieties, the applicability is limited. As for the analog input control, can support almost all of the inverter is, although the function is relatively simple, but the main function can realize speed, can meet the use requirements of the majority of occasions, universal.

Q:What are the key points of frequency converter maintenance?: Selection of frequency converter and installation noticeType selection of frequency converter in general should pay attention to the matters (such as input supply voltage, frequency, output power, load characteristics and so on), also requires a good match with the corresponding motor requirements during normal operation, giving full play to the advantage of energy saving at the same time, to avoid the overload operation, and try to avoid dragging equipment such as pumps the inefficient work area, to ensure the efficient and reliable operation.The installation environment of inverter must try to be clean and dust, and has good ventilation environment, ventilation conditions can be considered the side wall at the bottom of the inlet exhaust, and the inverter is installed, the top and side shall be sufficient for the minimum cooling distance, inverter inverter heat dissipation, in addition, there are certain requirements the environmental humidity, high humidity, electrical insulation to reduce the inverter itself, bar metal parts easy to corrosion, and the humidity is too low and easy to cause insulation damage, generally keep the humidity between 40%-90%.

Q:What do you mean by the capacity of the inverter and the capacity of the motor?: Because the motor consumes active power and consumes reactive power, and the reactive power is also occupied, the motor with 70KW can only be usedThe power is known to everyone

Q:Can 220V use frequency converter to drive three-phase motor with 380V?: Can not. The inverter is not step-up, single-phase 220V AC frequency converter into it is three-phase 220V AC motor is connected if your star angle connection can be changed, if the corner there's no way, after the motor power will be reduced about 4/10.

Q:Why does the frequency change when the frequency converter regulates the frequency?: That's for sure. The curve of voltage and frequency should be set according to the load condition, but after the rated frequency of the motor, the voltage is kept at the rated voltage

Q:What is the main function of the frequency converter on the machine tools?: The following example to three inverter in the application of the note for example!CNC machine tool is a kind of flexible and efficient automatic machine tool. It can solve the complicated, precise and small batch processing problem. It is very important to improve the machining accuracy and efficiency of CNC machine tools by rationally controlling the spindle of NC machine tools.

Q:Delta inverter fault output which parameter is set?: Parameter settings, class failures, frequency converter in use, whether it can meet the requirements of the transmission system, the parameter settings of the inverter is very important, if the parameter is not set correctly, it will cause the inverter not to work properly.

Q:What is the difference between inverter energy consumption braking and motor energy consumption braking?: Your question, I think it is the difference between regenerative braking and braking of the motor function for active inverter regenerative braking to use inverter feedback power, so there is the braking inverter of the argument?? First of all, define some of your concepts, the motor is divided into reverse braking, energy consumption braking, regenerative braking three. The energy consumption braking of the inverter is called the energy consumption braking by using the braking resistance in the DC loop to absorb the regenerative electric energy of the motor,The utility model has the advantages of simple structure; no pollution to the power grid (for comparison, action and feedback) low cost; the disadvantage is low efficiency, especially to consume a lot of energy and braking resistance will be in frequent braking capacity will increase.
