Q:Ask, what is the ratio of frequency converter?
Three inverter operation indicator light, the output frequency from 0.0Hz to potentiometer set frequency and the output frequency ratio is 1:1.5:2, adjust the tone potentiometer, change the motor speed and the speed of three units, according to the proportion of linkage. The output frequency of the three inverters can be adjusted with three Trimming Potentiometer respectively.
Q:What does the brake unit on the inverter mean?
When the motor is fast stopping, the motor will feedback the energy to the converter, causing the DC bus voltage to rise or even damage the IGBT. Therefore, it is necessary to use the braking unit to save the part of the energy to protect the converter.Inverter braking a lot, can refer to:
Q:Where is the difference between soft starter and converter?
The utility model is mainly composed of a three-phase anti parallel thyristor connected in series between the power supply and the controlled motor, and an electronic control circuit thereof. Different methods are adopted to control the turn-on angle of the three-phase anti parallel thyristor, so that the input voltage of the controlled motor varies according to different requirements, and different functions can be realized. 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. 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. Soft starter and converter
Q:How can I control the frequency converter with a computer?
Variable frequency speed control has been applied in the industrial field as the main means of AC motor speed control is very extensive, it has a wide speed range, steady speed and high precision fast dynamic response for a wide range of technical performance and reliable operation, has gradually replaced the DC motor speed control system. There are three main control modes of inverter: 1. through inverter panel operation, that is through the operation panel to change the output frequency and other operating parameters; 2. in the frequency converter analog input 0 ~ 10V or 4 ~ 20mA signal, by changing the size of input analog control of inverter output frequency converter; 3. through communication port (for RS485 control). The first method is generally used for manual adjustment and parameter setting on the spot, and the latter two are mostly used for automatic adjustment and remote control.
Q:What is the TTK converter produced?
Characteristic:Compact structure design, flexible installation, advanced control algorithm: space voltage vector control technology, power failure restart, automatic voltage adjustment, dead time compensation, energy saving operation,The main and auxiliary setting, built-in PID, simple PLC, oscillating frequency and zero frequency difference, length control, precision control requirements; design and test in accordance with international standards, to ensure the reliability of the product; choose rich accessories.
Q:What does a frequency converter do?
Frequency converter1. What is a frequency converter?The frequency converter usually uses the on-off function of the power semiconductor device to change the power frequency power to another frequency energy control device.2, what is the difference between PWM and PAM?PWM is English Pulse Width Modulation (pulse width modulation), according to the law must change the pulse of the pulse width in a tone adjustment output and waveform.
Q:Schneider 303 4KW frequency converter F 013 trouble shooting method
If the converter is overloaded, it is recommended to check the set acceleration time and whether the load is blocked or not.
Q:What does "frequency" in household appliances mean?
The technology of frequency conversion technology called frequency conversion technology and home appliances in 1970s AC control by changing the frequency of the AC current, household appliances gradually began to appear frequency, electromagnetic cooking device, inverter lighting apparatus, inverter air conditioner, microwave frequency, variable frequency refrigerator, IH (induction heating cooker), inverter washing machine etc.. In the latter half of 1990s, household appliances relied on frequency conversion technology, mainly aiming at high function and power saving. For example, with high speed, high output, good control performance, small light weight, large capacity, high comfort, long life, safe and reliable, mute, power saving and so on.
Q:Frequency converter size selection
You refer to the type and parameters of the frequency changer to select.
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
