- Q:How can I learn the converter well?
- Frequency converter training teacher suggested: Theory + practice combinedTheory: understand the frequency converter each parameter meaning, the frequency changer principle, the control way, the instruction manual, the approximate operation, knows how the matterPractice: combined with some special requirements of practice to do the debugging, this needs the accumulation of experience
- Q:Not to say that the inverter speed is mainly down frequency, how can I see the frequency rise to 60HZ, so that the three-phase motor is not more than the rated speed?
- When the high speed motor is driven by a transducer, the higher the higher harmonic is, the higher the output current value is due to the small reactance of the high speed motor. Therefore, the type selection of frequency converter used in high speed motor is slightly larger than the selection of ordinary motor.And if you want a long cable converter operation, this time to take measures to curb the influence of long cable on the coupling capacitor, to avoid the shortage of inverter output, so in this case, the frequency converter to enlarge the capacity of a file or install the output reactor in the inverter output.And for some special applications, such as high temperature, high altitude, at this time will cause the inverter derating, frequency converter to enlarge the capacity of a block.
- Q:What is the main harmonic produced by a transducer? How about the degree?
- To reduce the influence of harmonics, various measures can be taken, but for the inverter, the main circuit is to install an AC reactor.The input side of the inverter generates the harmonic mechanism: for the inverter, as long as there is a rectifier circuit on the power supply side, it will produce harmonics caused by nonlinearity. Based on the three-phase bridge rectifier circuit for example, AC grid voltage for a sine wave, square wave AC input current waveform, the waveform, according to Fourier series can be decomposed into fundamental and harmonics, usually containing 6m + 1 (m=1,2) harmonics, the harmonics in power grid. A single fundamental wave, combined with several harmonic waves, is called an abnormal wave
- 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:How to maintain the frequency converter will not damage, or regular maintenance?
- Replacement of spare parts is a common maintenance method of general inverter, inverter composed of various components, some parts of the work for a long time after its performance will gradually decrease, aging, which is the main reason of inverter fault, in order to ensure the normal operation of equipment for a long time, the device should be replaced regularly:
- Q:How to deal with the fault Yaskawa inverter GF
- This problem most likely. While G7 or F7 are generally Holzer Holzer sensor, sensor due to temperature. The influence of environmental factors such as humidity, work is easy to drift, to report "GF", another reason may be: E2-01 improper setting may also reported GF fault.
- Q:Surface grinder can add frequency converter, what are the advantages and disadvantages?
- Three frequency converter successfully used in NC machine toolsIn recent years, with the rapid development of the economy, the machine tool industry has also made rapid progress: it is reflected in the wide application of new technology and the obvious improvement of enterprise benefit. At present, the mainstream of consumption in machine tool industry is CNC machine tools. From the domestic and international market demand for CNC machine tools, after the NC machine tool market has the following characteristics: first, the economic CNC machine tools is the mainstream of the future products. Two, using new technology to reduce costs and improve product stability is the key to enterprise survival. Below we in the machine tool drive aspect uses the frequency control speed to say SAJ frequency changer in this profession application situation:
- Q:What role does input and output reactor play?
- Enter the reactor to suppress the surge voltage and surge current protection, frequency converter, and prolong its service life and prevent the harmonic interference, at the same time as the speed control inverter adopts frequency conversion mode, so often produce harmonics and waveform distortion in the speed, will affect the normal use of equipment, therefore, should be installed in a line choke the input end of the inverter can improve the power factor and harmonic current suppression filter, harmonic voltage and harmonic current, improve the quality of power grid.
- Q:Delta inverter fault output which parameter is set?
- Overload overload fault include frequency overload and overload. The electric machine may be accelerated in short time, the DC brake is too large, the grid voltage is too low, the heavy load causes. Usually by extending the acceleration time and prolong the braking time, check the power voltage. The heavy load, the motor and inverter can not drag this may be due to mechanical load, lubrication is not good. The former must replace high power motor and inverter; if the latter want to overhaul production machinery.
- 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, generally single-phase is allowed to + 20% fluctuations, three-phase is allowed to + 15% fluctuations.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.
