Q:How does MM430 frequency converter always report F003 fault?
To solve the problem, then check the original power of the line is loose, the power cables are quickly burnt, after fastening normal, thank you enthusiastic support, thank you!
Q:Delta inverter fault output which parameter is set?
1 undervoltage show that the inverter power input part of the problem, you need to check before you can run.  5.2, the temperature is too high, such as motor temperature detection device, check the cooling situation of the motor; inverter temperature is too high, check the frequency converter ventilation.
Q:Can 220V use frequency converter to drive three-phase motor with 380V?
If it is a star connection instead of a three phase 220V AC input, will the efficiency of the motor be reduced? Can you achieve the efficiency of the original motor 380V?
Q:What are the basis of the frequency converter to choose?
According to the applied industry.The application of inverter industry RGB field is widely used, the main products are: SAJ-S simple ultra small, SAJ-M mini, SAJ-G universal, SAJ-F type, SAJ-P type wind pump, SAJ-Y injection molding machine type, SAJ-Z type, heavy machine industry, naked personalized products, high performance vector inverter S350.
Q:How does the PLC process the inverter output signal?
1. The analog signals of the converter (such as the 4~20mA signal) are received in the analog input module of the PLC (for example, the EM235 module)2, the input signal processing (32000 digital quantity into 50HZ frequency signal)3. Compare the resulting frequency signals with their own internal settings
Q:Which country invented the inverter?
PC power supply using bridge rectifier, capacitor filter circuit will make the traditional AC input current waveform distortion, inject a large amount of high harmonics to the power grid, so the grid side power factor is not high, only about 0.6, and caused serious harmonic pollution and interference on the power grid and other electrical equipment. As early as the early 80s, the harm caused by higher harmonic currents caused by such devices has attracted much attention. In 1982, the International Electrotechnical Commission formulated the IEC55 2 specification (revised standard harmonic limit later is IEC1000 - 3 - 2), the power electronic technology, many workers began to harmonic filtering and power factor correction (PFC) technology research. The introduction of PFC circuit in electronic power supply can greatly improve the utilization efficiency of electric energy.
Q:Inverter switch display poff
The difference between the display value and the measured value shows that the bus detection circuit is abnormal if the deviation is larger. Conversely, if the two value deviation is minimal or equal, the missing phase signal is abnormal. At present, there are two kinds of bus detection circuit used in our company: resistance voltage divider and operation comparison amplification (TL082). Corresponding to the detection circuit output 0 - 3.3V corresponds to the actual bus 0 - 1000V, the two circuits are relatively simple, maintenance only need to test the key point voltage in the circuit, you can easily find the fault point.
Q:Can the frequency converter speed up?
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 a frequency converter?
Frequency conversion technology is born with the need of AC motor stepless speed regulation. After 1960s, the power electronic devices through SCR (SCR), GTO (gate turn off thyristor (BJT), bipolar power transistor), MOSFET (metal oxide semiconductor field effect transistor), SIT (static induction transistor), SITH (static induction thyristor (MGT), MOS control MCT (MOS) transistor, thyristor controlled), IGBT (insulated gate bipolar transistor), HVIGBT (high voltage insulated gate bipolar transistor) device to update the development process, to promote the continuous development of power electronics technology. The beginning of 1970s, PWM VVVF (PWMVVVF) control has aroused great attention. In 1980s, PWM mode optimization, as the core of frequency conversion technology, attracted people's interest and obtained many optimization models, among which the saddle wave PWM model was the best. Since the latter half of the 1980s, the VVVF inverters in developed countries such as the United States, Japan, Germany, Britain and other developed countries have already been put into the market and have been widely used.
Q:Delta frequency converter VFD-M series multi section speed command problem
Three speed motor static acceleration setting speed, then slow down to stop, in fact, frequency case should be motor frequency 30Hz set frequency converter 30Hz, and then to start and stop signal requirements (plus or minus speed, according to the scene set P-10 P-11)
