Q:What role does input and output reactor play?: The working principle of the reactor: the interference of capacitance and inductance in the circuit to the AC is called reactance. The inductor has the function of restraining the change of the current and the phase shift of the alternating current, and the winding static induction device with inductance is called a reactor. The dead are common reactor used in the power system with series reactor and shunt reactor. Series reactors are mainly used to restrict short circuit currents, and are connected in series with or parallel with capacitors in filters to limit the higher harmonics in the power grid. Reactors in the 220kV, 110kV, 35kV, and 10kV power grids are designed to absorb charging, capacitive, reactive, and reactive power in cable lines. The operating voltage can be adjusted by adjusting the number of shunt reactors.

Q:What is called vector converter?: The vector is what we (the mainland) says. The vector is generally used in the literature of Hong Kong and Taiwan. The meaning is roughly the same as that of Bush and bush. Vector control is mainly a concept of decoupling of motor models

Q:1, the frequency converter to the motor cable should be shielded cable? 2, whether there are specifications?: Do not use shielded cables have several conditions: the first is from the inverter to motor wear long steel pipe laying cable. Second is the frequency converter to the motor cable line routing (cable bridge, cable ditch), there is no analog signal cable or other weak signal cable. Otherwise, from the debug runtime, if the inverter cable cable line motor and analog signal very close, even if the analog signal shielded cable control cable when the motor running is still very obvious interference of analog signals, especially large power motor.

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: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: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:What is the over-current of the inverter?: The reason of the frequency converter itself:?1, parameter setting problem: for example, the acceleration time is too short, the PID regulator's proportion P, the integral time I parameter is unreasonable, the overshoot is too big, causes the frequency changer output current oscillation.?2 、 frequency converter hardware problem:

Q:Surface grinder can add frequency converter, what are the advantages and disadvantages?: SAJ inverter in the industry's specific applicationZhejiang Kanmen machine tool factory mainly produces all kinds of economic type simple NC machine, due to the higher failure rate of electromagnetic clutch speed regulation, realize VVVF system has more advantages, so using VVVF inverter to achieve the three. The details are as follows:

Q:How does the PLC process the inverter output signal?: Frequency converter frequency signal will actually be converted to 4-20mA signal output, access to the PLC AI channel, SIEMENS 200 PLC, some CPU module comes with AI input, but also has a dedicated AI expansion module. What's left is software programming

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.
