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:How to choose frequency converter?: Frequency converter (Variable-frequency, Drive, VFD) is the application of frequency conversion technology and microelectronics 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.

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?: Excessive temperatureIn addition there are high temperature transducer fault, such as the occurrence of a high temperature alarm, after checking the temperature sensor is normal, may be caused by the disturbance, faults can be shielded, also should check the ventilation fan and inverter. For other types of failures, it is better to contact manufacturers for quick and feasible solutions.

Q:How do you set the frequency with panels?. What are the specific steps?: Concrete steps are:1, the parameter 700 is the starting signal, the 1 is the panel button starting, and the 2 is the external signal starting;2, the parameter 1000 is the frequency setting value, and the 1 is the panel lifting mark key to change the frequency, and 2 is the external analog signal change.3, the starting signal is set automatically, then the parameter 1000 is 1, the panel is set frequency, and the parameter 1031 is set to 1 so that the frequency value after the change is saved automatically.

Q:I would like to ask, the inverter in use in the grid is very high?: Yes, because the harmonic generated by converter works has certain influence on the quality of power grid, so the demand for power grid is higher. Frequency converter (Variable-frequency, Drive, VFD) is the application of frequency conversion technology and microelectronics technology, by changing the power supply frequency of the motor to control AC motor power control equipment. The frequency converter adjusts the voltage and frequency of the output power by the breaking of the internal IGBT. According to the actual needs of the motor, it provides the required power supply voltage, and then achieves the purpose of energy saving and speed regulation,

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:The frequency converter is in use suddenly the speed reduces, then the debugging is out of control, how to do?: Among them, overvoltage is the most common phenomenon. After the overvoltage is generated, the inverter will prevent the internal circuit from damaging, and its over-voltage protection function will make the inverter stop running, resulting in the equipment can not work properly. Therefore, measures must be taken to eliminate excessive voltage and prevent the occurrence of faults. As the frequency converter and motor applications are different, the causes of over-voltage are not the same, so we should take appropriate countermeasures according to specific circumstances.

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: There is no doubt that the sound we hear is the sound produced by mechanical vibrations. When the inverter is idle, just as upstairs, it says only a slight noise from the fan, but there is a squeal when loaded

Q:Why does the frequency converter cause interference?: Method for solving interference caused by frequency converter:Adopt software anti-interference measures: specifically, the carrier frequency of the inverter is lowered through the man-machine interface of the inverter, and the value is reduced to an appropriate range. If this approach does not work, then only the following hardware anti-interference measures can be taken.Carry out the correct grounding: through the field investigation, we can see that the site of the ground is not ideal. The correct grounding can not only effectively suppress external interference, but also reduce the interference of the equipment itself to the outside. It is the most effective measure to solve the interference of frequency converter. Specifically, do the following two points:

Q:How do you understand the ramp up (descent) time of the inverter? Thank you!: The reverse is the drop time, or the 0 speed. Water pumps and fan motors are basically not required to change. If it is an emergency stop, it is usually 3 seconds (depending on the frequency converter and process requirements).
