- Q: At the base block Yaskawa inverter is what reason?
- This is the base block command, when the external input block command signal, the frequency converter will appear this code, the emergence of this code, the motor will rotate freely, does not affect the use.
- 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: How does the frequency converter fit the brake unit and the brake resistor?!
- To calculate how much energy consumption, can be converted into electric current, to select the brake unit. You can also choose the braking resistance (to consider resistance temperature characteristics to choose), then select the brake unit with matching (see manufacturer manual).
- Q: Today, I was asked the question, and I also brought it to you to share the following Oh!
- Inverter inside the circuit is inverterIt is a control of communication -- direct current -- CommunicationDC alternating current is called inverter
- Q: How do two inverters synchronize?
- Use a potentiometer to control which one is in front. Which of the following uses synchronization to track speed and position?. (a PLC (or a special control panel) + position sensor (can be a variety of proximity switch + CAM) two, there must be a little better, by rotating the transcoder, can also be used for phase control of motor position relative to the strict requirements).
- Q: The frequency converter works with sharp noises. What's the process of converting electrical energy into mechanical energy?. The mechanism of sound making. Thank you
- The input is AC 50Hz sine wave output frequency variable, but still want to be sinusoidal. But due to various reasons such as the efficiency and control it is not directly output sine wave. It is the original inverter with high frequency sine wave modulation is Fang Bo, will be on the radio. As the modulation principle this is also called the square wave carrier. Between hundreds to thousands of HZ. In the range of our hearing. When it can be produced by mechanical vibration equipment such as reactors will sound when conducting ]. We hear is the sound.
- 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: 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: Can a power converter be used in a motor with small power? Will it burn the motor?
- Yes, the motor will not burn, if it is a small power converter, with large power motor, frequency converter will burn point
- Q: What does "G" and "P" mean in the converter model?
- General inverter said, "G" and "P" type refers to the inverter general type and fan pump difference, G type inverter applies to the general machinery class load, and P type is used in the wind or water pump.
