Q: What does a frequency converter do?: What is the difference between a voltage type and an electric current type?The main circuit of the inverter can be divided into two categories: voltage is DC voltage source converter for AC inverter, the DC circuit is the filter capacitor current is DC converter; current source for AC inverter, the DC circuit filter inductance stone.

Q: The functions of frequency converter and UPS are similar, especially the power frequency UPS?: The frequency converter is used to control the motor stepless speed regulation. The power frequency UPS is an uninterrupted power supply, which is used for the power supply of the precision electronic equipment

Q: Which country invented the inverter?: 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.PFC is the term "power factor", which is mainly used to characterize the efficiency of electronic products in the utilization of electric energy. The higher the power factor, the higher the efficiency of power utilization.

Q: What are the key points of frequency converter maintenance?: Selection of frequency converter and installation noticeType selection of frequency converter in general should pay attention to the matters (such as input supply voltage, frequency, output power, load characteristics and so on), also requires a good match with the corresponding motor requirements during normal operation, giving full play to the advantage of energy saving at the same time, to avoid the overload operation, and try to avoid dragging equipment such as pumps the inefficient work area, to ensure the efficient and reliable operation.The installation environment of inverter must try to be clean and dust, and has good ventilation environment, ventilation conditions can be considered the side wall at the bottom of the inlet exhaust, and the inverter is installed, the top and side shall be sufficient for the minimum cooling distance, inverter inverter heat dissipation, in addition, there are certain requirements the environmental humidity, high humidity, electrical insulation to reduce the inverter itself, bar metal parts easy to corrosion, and the humidity is too low and easy to cause insulation damage, generally keep the humidity between 40%-90%.

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?: Mainly below the basic frequency of speed regulation,If higher than the basic frequency, that is constant power speed, that is, the higher the motor speed, the smaller the torque

Q: What is the working principle of elevator frequency converter?: Yaskawa 616G5 transducer current vector in the world as one of the inverter control, speed range to reach 1:1000, the control accuracy of 0.02%, with the starting torque at zero speed can reach 150% characteristics. In particular, Yaskawa unique all fields, automatic torque boost function can get comfort and good stability in the lift drag in.G5 can accept controllers such as multi speed frequency command PLC or analog voltage and current instruction; can adapt to all kinds of motor vector control and self-learning to obtain good characteristics; low speed starting smoothly excellent reliability and high cost of hardware.

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,: Two inverters with the same frequency and start signal, so that it can be synchronized; another way is to do in front of a given frequency inverter with potentiometer, given analog output signal of the first station to do second machines, it can be done simultaneously; but you have to say clearly what is what specific brand series in order to further clear the inverter parameters, otherwise only vague answers.

Q: What does "EPCU" mean in a frequency converter?: But look at your inverter has also been used for some time, if not before, and now appear, it is estimated that the hardware is broken, and manufacturers communicate maintenance!

Q: 5.5KW frequency converter with 4.5KW deep water pump, pressure regulator by conveying signal to frequency converter start normal, the pressure to reduce the frequency converter after the start, to about 30Hz in order to maintain the pressure about shocks, 30 seconds inverter over-current alarm. Can it be the fault of the frequency converter? How should I check it?: Once the inverter has hardware faults, such as rectifier, inverter circuit and so on. The IGBT module may be damaged, and most of the time it will damage the drive components. The most easily damaged devices are the regulator and the optocoupler. Conversely, components such as capacitance, leakage, breakdown, and optocoupler aging can also cause IGBT modules to burn out or frequency conversion, and output voltage is unbalanced. Check if there is a problem with the drive circuit, and compare the resistance of the trigger terminals when the circuit is not switched on. The voltage waveform at the trigger end can be measured when the power is switched on. However, some inverters are not equipped with modules and can not switch on, when the module P end of the series into a false load, to prevent detection, mistakenly touch the originator or other circuit burned module. In this case, the frequency converter has been seriously damaged (by measuring whether the input and output are short circuited), then there should be special technical personnel maintenance, and generally may not re energized, so as not to expand the scope of failure.

Q: Frequency converter OC alarm, what's the matter?: Description of the OC fault in the inverter manual, following several explanations: the load side short-circuit current greater than OC, run jump failure is two times; the output of the inverter module circuit; current transducer; overload; acceleration and deceleration time is too shortEtc.. Some models do not use OC to mark such faults. They are explained by load side short circuit, frequency converter overload, serious ground fault and so on. This is of course the alias of OC fault.
