Q:What is the difference between SIEMENS inverter and built-in filter?: The filter is used for electromagnetic interference protection. Not only for the protection of electrical equipment, but also for the use of environmental protection. Inverter application environment is very extensive. Industry, light industry, commerce, civil, etc.. So the level of electromagnetic protection is also different.By the way。 If you disconnect the converter. See a coil on a board. That's the built-in filter. If you don't have it, you don't have that coil.

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:How much is the motor 90KW and the frequency converter selected?Colleagues suggest 110W?The cost will be higherIs it okay to choose 90KW?: You refer to the type and parameters of the frequency changer to select.

Q:What does Ro1c mean on a converter?: RO1C is the common terminal and the RO1A is normally closed, and the RO1B is normally open. The set of contacts is the output signal that is ready to run. That is, the self-test of the converter is completed and the output signal of the relay can be operated.

Q:That is, some parameters of the inverter, such as torque, current, frequency, etc., are displayed on the Kingview software interface, but not through the PLC. The idea that the MODBUS protocol between SIEMENS and 200PLC has never been successful before, so that's the idea of the ABB. If it can be achieved,Is it necessary to write the script program on the Kingview, and what problems should I pay attention to when using the MODBUS protocol in Kingview software?The problem is a little bit more, I hope the experts teach me this rookie! Thank you: As long as there are 485 communications can be, the frequency converter manual on the MODBUS protocol, the address of each parameter, in the king view on the link can do, and I hope to adopt.

Q:What does "G" and "P" mean in the converter model?: Frequency converter (frequency transformer) is usually the use of power semiconductor devices through the role of switching the power frequency to another frequency power control device. 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.

Q:Why does harmonic generator produce harmonic? What's his working principle?: Is the inverter harmonics in converter running, need to input power supply of high power diode rectifier (or transistor / inverter module) of inverter; in the inversion process, the high-order harmonic generation in the input / output circuit; inverter harmonic to the power supply system, load and his nearby electrical equipment interference.

Q:Which country invented the inverter?: Since 1960s, thyristor and its upgrade products have been widely used in power electronic devices. But its speed performance is far from meeting the needs. In 1968, the high-tech enterprises represented by Danfoss began to batch produce frequency converters and opened a new era of inverter industrialization.The beginning of 1970s, PWM VVVF (PWMVVVF) speed research get breakthrough, in 1980s after the microprocessor technology is perfect makes the algorithm easier to achieve.In the middle and late 1980s, VVVF converter technology in developed countries, such as America, Japan, Germany and Britain, was practical and the products were put into market and widely used. The earliest converters could have been bought by British and developed by British patent. However, the United States and Germany, with the advantages of electronic components production and electronic technology, high-end products quickly seize the market.Entered in twenty-first Century, the domestic inverter gradually rise, has gradually seize the high-end market. Shanghai and Shenzhen to become the forefront of domestic inverter development, emerged as Huichuan inverter, inverter, AMB inverter, frequency converters and a number of well-known domestic inverter. The AMB inverter was established in 1998, is one of China's first production of inverter manufacturers. Over the past decade, as the cornerstone to AMB rich cultural heritage, to support growth, enterprise quality system ISO9000 TUV earlier passed the certification, was awarded the "national high tech enterprise", has been appraised as "China user satisfaction of the ten domestic brands inverter".

Q:If you don't plug in the PG card, do you use PLC's PID control?Plug in the PG card and the PLC PID control, which is reliable and precise?: If there is a PLC encoder as a speed sensor signal, you can access the PLCPLC analog output (or communication) as a given value of the inverterUse PLC's PID instruction to complete the speed closed loop control of the converter.Note: if you are not using vector control of the inverter, you can.For example: horizontal transmission of non vector control or pump fan class.

Q:Frequency converter, fault, contact action: Frequency converter is the application of frequency conversion technology and micro electronics 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.
