Q: Application of ABB frequency converter: 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: Why does the frequency converter cause interference?: Isolation of interference: the so-called interference isolation is the separation of the source of interference from the susceptible part from the circuit so that they do not generate electrical contact. Usually in the power supply and controller and transmitter amplifier circuit, in the power line using isolation transformer, so as to avoid conduction interference, power isolation transformer can use noise isolation transformer.

Q: Can the frequency converter 7.5KW take the motor with 11KW?: Inverter 7.5KW can not take 11KW motor, so that may cause overload inverter.Usually, the frequency converter 7.5KW can take about 5KW motors.

Q: Where is the difference between soft starter and converter?: Are two completely different uses of the product. The inverter is used for the need for speed place, its output voltage and frequency change not only change; the soft starter is actually a regulator for motor starting, output voltage and frequency change not only change. Inverters have all of the soft starter functions, but they cost much more than soft starters and have a much more complex structure.

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: What's the function of this brake unit?: The normal asynchronous motor in power loss, but also because of the inertia and load rotor rotate continuously for a period of time, at this time, due to the current of the rotor motor will still exist, such as the generator, sent to the power supply current. When a short circuit fault occurs, the motor also provides feedback current.

Q: PT100 temperature patrol instrument, when the converter is not open, the measurement is normal. Once opened, it shows completely disorder, and sometimes there are puzzling characters. How can I solve this problem? Please enlighten master!: In the complex electromagnetic environment, AnyWay advocates the idea of digital front end, that is, in the vicinity of being measured, the signal will be digitized, and then the uploaded information will be uploaded to the host computer through digital communication. Digital transmission is much better than analog transmission in anti-interference ability. If the electromagnetic interference is very large, the transmission line can be changed into optical fiber transmission. In this way, the transmission link can completely avoid interference.

Q: What are the possible causes of frequency hopping overload?: If the motor and inverter adapter, because the motor overload in inverter, this time is called the overload overload of the transducer, the current inverter rated current is compared; if the motor rated current is less than the rated current of inverter, the correct input motor nameplate and protection, the overload protection is often referred to as motor overload protection. Therefore, we must distinguish the specific circumstances of the current protection. Because of the overload point of the converter and the overcurrent point of the converter, the two protection alternates frequently.

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 a sharp sound can only prove that you have problems with frequency conversion, frequency conversion stable operation can only hear the sound of the fan slightly. Although we are engaged in frequency conversion, but let me tell you this mechanism, really can not say, you can use frequency conversion, and play to his limit, have been very difficult.

Q: What are the contents of frequency converter maintenance?: Operators must be familiar with the basic principles of inverter, functional features, with basic knowledge of electrical operations. Before checking and maintaining the frequency converter, the total power supply of the equipment must be cut off, and the inverter Chang lamp will be completely extinguished.
