Q: High-voltage converterGeneral inverterPump frequency converterEngineering frequency converterCould you tell me some frequency converter according to the class?: Frequency converter classification method can have many kinds, according to the technical characteristics of the points, according to the voltage level to be divided, and also according to the application characteristics of the points. It's hard to make a brief statement. The four types of frequency converters you list are based on different classification methods. The above is according to the technical classification to tell you, more complex, I will not say more.

Q: What does the base frequency 60Hz represent in the inverter?: For example: if the rated frequency of the motor is 20HZ, the fundamental frequency should be set to 20HZ; if the rated frequency of the motor is 33.3HZ, the fundamental frequency should be set to 33.3HZ; if the rated frequency of the motor is 50HZ, the fundamental frequency should be set to 50HZ; if the rated frequency of the motor is 60HZ, the fundamental frequency should be set to 60HZ; if the rated the working frequency of the motor is 100HZ, the fundamental frequency should be set to 100HZ.

Q: Ask, what is the ratio of frequency converter?: Three inverter operation indicator light, the output frequency from 0.0Hz to potentiometer set frequency and the output frequency ratio is 1:1.5:2, adjust the tone potentiometer, change the motor speed and the speed of three units, according to the proportion of linkage. The output frequency of the three inverters can be adjusted with three Trimming Potentiometer respectively.

Q: What does the RUN key on the inverter mean? How do you use it?: According to the actual needs of the motor to provide the required power supply voltage, and then to achieve energy saving, speed control purposes, in addition, there are many inverter protection functions, such as over-current, overvoltage, overload protection, etc.. With the continuous improvement of the degree of industrial automation, inverter has also been widely used.

Q: Why does harmonic generator produce harmonic? What's his working principle?: Is the inverter harmonics in converter running, need to input power supply of high power diode rectifier (or transistor / inverter module) of inverter; in the inversion process, the high-order harmonic generation in the input / output circuit; inverter harmonic to the power supply system, load and his nearby electrical equipment interference.

Q: How can I control the frequency converter with a computer?: The commonly used PLC and DCS control system in industrial area are applicable to the conditions of inverter interface control module, can realize the closed-loop converter convenient automatic control in the control system, widely used in large and medium. The control device for some smallexperimental device and embedded processor in inverter control, generally also need to deal with the keyboard input, display, data acquisition and other work such as process control, this control is more suitable for single-chip control system as the core, and uses PLC and operation panel, it can achieve the function but the cost is too high. Should not be used.

Q: What is the difference between inverter energy consumption braking and motor energy consumption braking?: A direct current is generated in the stator winding so that a fixed magnetic field is generated. At this point, the rotor cuts the magnetic field lines in the direction of rotation, resulting in a braking torque. Because the braking method is not like regenerative braking (using frequency converter), the energy generated by braking is fed back to the grid, but the energy is dissipated by the motor alone, so it is called energy consumption braking. The utility model is also used for braking by direct current in the stator winding, so the energy consumption braking is called DC injection braking. By using the backward switch Q to return the point voltage back to the grid, the armature current will become a copy, and the current will be of the same magnitude, resulting in a great braking torque of the motor, which will stop the motor.

Q: What is the frequency converter AVR?: When the input voltage deviation from the rated value, the function can keep the output voltage constant, so under normal circumstances should be AVR action, especially when the input voltage is higher than the rated value, to protect the motor from excessive voltage caused by long-term insulation damage or high magnetic density caused by excessive heating core.

Q: How do you set the frequency with panels?. What are the specific steps?: 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: What is the working principle of a three phase AC asynchronous motor inverter?: I. operating temperature. The internal electronic components of high power, extremely easy to be influenced by the working temperature of the product, the general requirements for 0 ~ 55 degrees, but in order to ensure the safe and reliable work, use should 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 in the product specification. Absolutely no heating element or easy heating element shall be installed on the bottom of the converter.
