Q:At the base block Yaskawa inverter is what reason?: Garbage in Yaskawa signal board on the small line contact oxidation, look good, this is a kind of weak signal, and for safety relay is not the safety loop at high levels in a small line short circuit, 1000 Yaskawa A factory is shorted for a long time have blocked the oxidation base

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: ABB converter supports MODBUS protocol, can be directly connected to the ModbusRTU in your choice of Kingview, device configuration, set up converter address directly in Kingview read the corresponding parameters can be

Q:Today, I was asked the question, and I also brought it to you to share the following Oh!: The frequency of the electricity we use everyday is 50Hz. If we want to change the frequency, we have to change it through the frequency converter.The working principle of frequency converter is to change the frequency alternating current into no frequency direct current, and then control it by electronic circuit so that it can adjust its frequency alternating current at any time.The inverter is similar to the back half of the inverter, which converts the direct current into alternating current.

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:Does the number of inverter settings differ from the number of motor poles, and does it affect the use?: Frequency converter has a number of requirements, if the motor is not set by the number of motor parameters, I think there will be the following problems, but may occur, I have not been verified:

Q:What are the parameters of the frequency converter? Thank you: Inverter function parameters are many, generally have ten, or even hundreds of parameters for users to choose. In practical applications, it is not necessary to set and debug each parameter, most of which can only be used as factory settings. But some parameters have great relationship with the actual use, and some are related to each other, so they should be set and debugged according to the actual situation.Because of the type of converter function are different, but the same function parameter name is not consistent, but the type of converter is almost always some basic parameters, can be done completely by analogy. The following parameters are basically used:

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:The frequency converter is in use suddenly the speed reduces, then the debugging is out of control, how to do?: Among them, overvoltage is the most common phenomenon. After the overvoltage is generated, the inverter will prevent the internal circuit from damaging, and its over-voltage protection function will make the inverter stop running, resulting in the equipment can not work properly. Therefore, measures must be taken to eliminate excessive voltage and prevent the occurrence of faults. As the frequency converter and motor applications are different, the causes of over-voltage are not the same, so we should take appropriate countermeasures according to specific circumstances.

Q:What are the possible causes of frequency hopping overload?: Because the overload is judged only by the current, it will happen at the start, stop, acceleration and deceleration, and constant speed operation. Moreover, the current and the asynchronous motor difference are inseparable, so the following conditions can be used for analysis and reference:

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.
