Q: At the base block Yaskawa inverter is what reason?: Garbage in Yaskawa signal board on the small line contact oxidation, look good, this is a kind of weak signal, and for safety relay is not the safety loop at high levels in a small line short circuit, 1000 Yaskawa A factory is shorted for a long time have blocked the oxidation base

Q: What's the frequency converter for? What does it look like?: The inverter is mainly used in industrial equipment, such as power plants, water plants, water supply equipment, large pumping station, it is basically a cuboid, a digital display control panel; and in the English show types into the universal type, fan pump type, vector control, different types should be used in different working conditions, voltage grade from 220V-10 million volts, currently has the localization.

Q: Knowledge, principle and operation method of frequency converter.: Basic classification of the working principle of frequency converter:Frequency converter working principle has been, so there are so many converters in the world for Mao is not the same? If you cry in this case, I can only say sorry, yes, but they can also do the classification (please open up the brain to process OCD pattern): classification according to the working mode of the main circuit, 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 converter 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 high performance frequency converter, inverter, high frequency inverter, single-phase inverter and three-phase inverter.

Q: What is the difference between frequency converter and servo driver?: The general use of the situation, such as high-speed, high-precision positioning equipment, servo, high power speed control using frequency conversion.Like the central air conditioning system, elevators and so on, many places use frequency conversion; like the textile machine, the placement machine, the plug-in machine uses the servo. In fact, many cases are used in conjunction with the two systems, according to the needs of the design arrangements.

Q: What is frequency conversion? What is the function of frequency converter?: Frequency conversion:1, the frequency conversion is to change the power supply frequency, thus adjust the load, play a role in reducing power consumption, reducing the loss and prolonging the service life of the equipment. Frequency conversion.2, the core of frequency conversion technology is frequency converter, through the power frequency conversion to achieve automatic adjustment of motor speed rate, the fixed frequency of 50Hz is changed to 30 - 130 Hz frequency. At the same time, the utility model makes the voltage range of the supply voltage reach 142 - 270V, and solves the problem that the voltage of the power grid is unstable, which influences the work of the electric appliance. The technique of alternating current control by changing the frequency of alternating current is called frequency conversion technology.

Q: How does the PLC process the inverter output signal?: 1. The analog signals of the converter (such as the 4~20mA signal) are received in the analog input module of the PLC (for example, the EM235 module)2, the input signal processing (32000 digital quantity into 50HZ frequency signal)3. Compare the resulting frequency signals with their own internal settings

Q: There is a feed and send system. Now due to the severity of the material is not the same as the two converters often change speed, the workers do not understand their own, often by, often bad now how to use the best way you can use a potentiometer or other method, control of the two frequency converter, synchronous operation. Is to adjust one, and the other also with the kind of frequency, so that you can let the workers themselves to open, and the two inverters, the same manufacturer, the same model, the same load,: The boss to the electronic parts store, a duplex potentiometer, resistance and frequency converter converter on you as well, so that the original line after the line on the inverter came up to double the potentiometer, ah, ah ah Wang simple to score

Q: What are the precautions for frequency converter wiring installation?: First understand the instructions, do not take the control line wrong, power line into the wire outlet is connected, you can debug it

Q: What does the RUN key on the inverter mean? How do you use it?: In general, when selecting panel operations (when the panel of the inverter is the control source of the inverter), it is the meaning of the "running" button. Press it, the converter will run, turn or reverse

Q: What is the main harmonic produced by a transducer? How about the degree?: The frequency converter is a nonlinear load, which absorbs nonsinusoidal current from the grid and causes the voltage distortion of the network. It is not only a harmonic source, but also a harmonic receiver. As harmonic source, it has different influence on all kinds of electric equipment, automatic device, computer, measuring instrument and communication system. As for the power supply line, due to the harmonic effect, the quality index of the power grid is deteriorated, the reliability of the power grid is reduced, the loss of the power grid is increased, and the service life of the electric equipment is shortened.
