Q: Frequency converter, fault, contact action: Frequency converter is the application of frequency conversion technology and micro electronics technology, by changing the power supply frequency of the motor to control AC motor power control equipment. The frequency converter is mainly composed of rectifier (AC DC converter), filter, inverter (DC AC converter), brake unit, drive unit, detection unit, micro processing unit and so on. Inverter by internal IGBT drive voltage and frequency off to adjust the output power, the power supply voltage required to provide according to the actual needs of the motor, so as to achieve the purpose of speed, energy saving, in addition, there are a lot of protection drive, such as over-current, over-voltage, overload protection and so on. With the continuous improvement of the degree of industrial automation, inverter has also been widely used.

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: What is the upper and lower limit of the environmental temperature to ensure the normal operation of the inverter?: Inverter environment temperature(1) working temperature. The use of frequency converter should pay attention to the environmental matters, the internal is high-power electronic components, is easily affected by the operating temperature, the product is generally required to be 0~55 degrees, but in order to ensure safe and reliable work, when usedShould be considered under the best control in 40 DEG C. In the control box, the inverter shall be installed on the upper part of the box, and strictly comply with the installation requirements of the product manual, absolutely not allowed to sendA heat element or a heat generating element is mounted close to the bottom of the inverter.

Q: What does "EPCU" mean in a frequency converter?: This code indicates external signal interference.It is possible that the power line and the signal line are coming together to check that the ground of the converter is ready.If not yet, that can only be considered in the inverter output end of the inverter output filter, or inverter output reactor to try.Frequency converter (Variable-frequency, Drive, VFD) is the application of frequency conversion technology and microelectronics technology, by changing the power supply frequency of the motor to control AC motor power control equipment.

Q: What is a frequency converter?: There are many classifications of inverter, the main circuit according to the classification, can be divided into voltage type inverter and current source inverter; switching mode in accordance with the classification, can be divided into PAM control inverter, PWM control frequency and high frequency PWM inverter control; in accordance with the principle of classification, can be divided into V/f control inverter, slip frequency control inverter and vector control inverter; according to use classification, can be divided into general inverter, high performance inverter, high frequency inverter, single-phase inverter and three-phase inverter.

Q: What are the parameters of the frequency converter? Thank you: That is to say, the upper and lower amplitudes of the output frequency of the inverter. Frequency * * is to prevent misoperation or external frequency set signal source failure, resulting in the output frequency is too high or too low, in order to prevent damage to a device protection function. In the application, according to the actual situation can be set. This function can also be used as a speed limit, if the conveyor belt, the conveying material is not too much, to reduce the mechanical and wear belts, be driven by inverter, and the inverter upper frequency settings for a particular frequency, so it can make the belt conveyor running on a fixed low speed work

Q: Why does harmonic generator produce harmonic? What's his working principle?: Harmonic generation mechanism of inverter inputThe main circuit of inverter is composed of AC-DC-AC, external input 380V/50Hz power supply through the three-phase bridge rectifier, a DC voltage, AC voltage by the capacitor filter and high power transistor switching element for variable frequency inverter. In the rectifying circuit, the input current waveform is a rectangular wave irregular waveform, according to Fu Liye series is decomposed into fundamental and harmonics, the harmonic frequency is usually 6N + 1 harmonic, the harmonic interference input power supply system. If the reactance of the supply side is sufficiently small and the commutation overlap angle can be neglected, then the n order harmonic is the 1/n of the fundamental current.

Q: I would like to ask, the inverter in use in the grid is very high?: In the process of using inverter, grid voltage fluctuation requirements is not high, the general phase is to allow + 20% fluctuations, three-phase is allowed 15% fluctuations, so most of the grid voltage can be satisfied, unless it is in the countryside, or more remote areas, the voltage change will exceed the allowable value. In addition, the frequency converter on the power grid harmonics also have requirements, if the harmonic content of more than 20%, will lead to frequency converter misoperation, false alarm, more serious circumstances, will lead to inverter out of control, or damage. However, most of the current harmonics will not happen, unless a large number of individual factories use frequency converters, servo, intermediate frequency furnace, welding machine and other equipment.

Q: What is the over-current of the inverter?: External cause:?1, the motor load mutation caused by excessive impact, resulting in excessive flow.?2, the motor and motor cable phase or insulation damage to each other, resulting in short circuit turns to the ground, resulting in over-current.?3, over-current fault and motor leakage reactance, motor cable coupling reactance, so choose motor cable must be selected according to requirements.?4. Power factor correction capacitor or surge absorption device on the output side of inverter.?5. When the speed feedback signal is lost or abnormal, it will cause excessive flow, and check the encoder and its cable.

Q: Can a power converter be used in a motor with small power? Will it burn the motor?: Large power converter can be used in small power motors, as long as the motor nameplate parameters, in the inverter motor parameters can be set, so that the inverter can provide the right protection.And。 Selection of frequency converter capacity, generally greater than the power of the motor more than one file.
