Q: What are the modes of operation of a frequency converter?: Frequency converter with motor no-load operation, 11 set motor power and pole number, to consider the work current of the converter. 21 set the maximum output frequency, frequency and torque characteristics of the inverter. VPf types include items such as maximum frequency, basic frequency and torque type. The highest frequency is the highest frequency that the inverter motor system can operate, because the highest frequency of the inverter itself may be higher, when the highest frequency allowed by the motor is lower than the frequency conversion

Q: High-voltage converterGeneral inverterPump frequency converterEngineering frequency converterCould you tell me some frequency converter according to the class?: According to the classification of link Transformation: (1) the AC-DC-AC converter is the first AC into DC rectifier through, and then transformed into the frequency DC voltage adjustable AC inverter, also known as indirect, is currently widely used general-purpose inverter. (2) can be divided into cycloconverter, is directly converted into AC voltage adjustable frequency AC, also known as direct inverter DC power supply according to the classification of properties: (1) the voltage type inverter voltage type inverter is characteristic of DC link energy storage device using a large capacitor load reactive power will be it is to buffer the DC voltage, DC power supply is relatively stable, smaller internal resistance and the equivalent voltage source, so that the voltage type inverter, are often used for load voltage changes in the larger situation. (2) current inverter current type inverter is characterized by large DC link inductance as a storage buffer of reactive power, which changes the current control, the voltage is close to sine wave, because the DC resistance is large, so that the current source converter (current). The characteristics of current source inverter (advantages) can restrain the load current is frequent and rapid changes.

Q: 1, the frequency converter to the motor cable should be shielded cable? 2, whether there are specifications?: Do not use shielded cables have several conditions: the first is from the inverter to motor wear long steel pipe laying cable. Second is the frequency converter to the motor cable line routing (cable bridge, cable ditch), there is no analog signal cable or other weak signal cable. Otherwise, from the debug runtime, if the inverter cable cable line motor and analog signal very close, even if the analog signal shielded cable control cable when the motor running is still very obvious interference of analog signals, especially large power motor.

Q: Today, I was asked the question, and I also brought it to you to share the following Oh!: The inverter (power converter, Power Inverter) is a kind of DC12V can be converted to DC and AC220V AC power the same, for general use of electrical appliances, power converter with a convenient car.

Q: What is called vector converter?: The vector is what we (the mainland) says. The vector is generally used in the literature of Hong Kong and Taiwan. The meaning is roughly the same as that of Bush and bush. Vector control is mainly a concept of decoupling of motor models

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: 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 a frequency converter?: The frequency converter is the electric energy control device that transforms the power frequency power to another frequency by the on-off function of the power semiconductor device. 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.

Q: I would like to ask, the inverter in use in the grid is very high?: In the process of using frequency converter, the demand for voltage fluctuation of power grid is not high. It depends on what brand of transducer. As a result, most of the grid voltage can meet the requirements, except in rural or remote areas where voltage changes exceed their permissible values. 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 do you mean by the capacity of the inverter and the capacity of the motor?: Capacity can be understood as active power + reactive power, such as the capacity of 100KVA inverter, is not 100KW motor,
