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: 1, requires two communications. The PLC and the Kingview use a communication port individually, and the PLC and the inverter use a communication port alone. 2, Kingview and PLC communication time, Kingview is the master station, PLC is from the station; and PLC and converter communication, PLC is the master station, frequency converter is from the station. 3, frequency converter control, do not use communication, use digital point output and analog output. 4, PLC and inverter as the slave station using Kingview configuration; Wang put the data to the PLC, let PLC run the program, go to the PLC of the configuration parameters of the inverter control read out, and then sent directly from the Kingview converter.

Q: Knowledge, principle and operation method of frequency converter.: The three major parts of the working principle of frequency converter:This is how the inverter works, but how does it work? Mainly composed of three components. (1) convert the power frequency power to the rectifier of the DC power: it transforms the power frequency power into the DC power supply. A reversible converter can also be constructed using two sets of transistor converters, which can be regenerated for their reversible power direction. (2) absorption in the converter and inverter voltage generated by the pulsating "flat wave circuit" in the rectifier DC voltage is rectified, ripple voltage with power frequency 6 times, in addition the pulsating current generated by the inverter to the DC voltage fluctuation. (3) the DC power conversion for AC power rectifier with "inverter": instead, the inverter is DC power converter for AC power required frequency, to the time the 6 switch off, you can get 3 phase AC output.

Q: First of all, I would like to achieve the frequency converter with motor static linear acceleration, high-speed linear deceleration stop processFirst question: I say kind of situation, three paragraph speed start, 0.1hz---> high 30hz-->0.1hzSecond problem: manual speed instruction 1, speed 2, speed 3 instruction instruction I want to use PLC to control three speed motor with three reverse contact dry. I understand speed instruction 1 is switched on (2, 3 connected) transmission section set the frequency with the frequency segment set 0HZ123 AssociationThird questions: manual section, speed command, main frequency and STEP1-STEP7 stage setting frequency, I use PLC analog to the frequency main frequency setting, plus and deceleration, STEP1-7 are set 0, can achieve what I wantInitial contact frequency converter, home pointing: 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)

Q: The frequency converter is in use suddenly the speed reduces, then the debugging is out of control, how to do?: Excessive voltage generation and regenerative braking, the so-called inverter over-voltage, refers to a variety of reasons caused by inverter voltage exceeds the rated voltage, concentrated in the DC bus frequency converter DC voltage. In normal operation, the DC part voltage of converter is the average value after three-phase full wave rectification.

Q: What does the base frequency 60Hz represent in the inverter?: The schematic diagram of the basic frequency parameters of the converter is shown in figure.Below the fundamental frequency, the output voltage of the converter varies with the output frequency, and the V/F= constant is suitable for constant torque load characteristics.Above the fundamental frequency, the output voltage of the inverter maintains the same voltage rating of the power supply, which is suitable for constant power load characteristics.

Q: There is a feed and send system. Now due to the severity of the material is not the same as the two converters often change speed, the workers do not understand their own, often by, often bad now how to use the best way you can use a potentiometer or other method, control of the two frequency converter, synchronous operation. Is to adjust one, and the other also with the kind of frequency, so that you can let the workers themselves to open, and the two inverters, the same manufacturer, the same model, the same load,: The boss to the electronic parts store, a duplex potentiometer, resistance and frequency converter converter on you as well, so that the original line after the line on the inverter came up to double the potentiometer, ah, ah ah Wang simple to score

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: Where is the frequency converter used?: In these industries, the use of small and medium power converters more, 220V/380V as its main model. Of course, the auxiliary facilities in these industries still have fans, pumps and inverters, but they don't use much.

Q: The frequency converter works with sharp noises. What's the process of converting electrical energy into mechanical energy?. The mechanism of sound making. Thank you: The input is AC 50Hz sine wave output frequency variable, but still want to be sinusoidal. But due to various reasons such as the efficiency and control it is not directly output sine wave. It is the original inverter with high frequency sine wave modulation is Fang Bo, will be on the radio. As the modulation principle this is also called the square wave carrier. Between hundreds to thousands of HZ. In the range of our hearing. When it can be produced by mechanical vibration equipment such as reactors will sound when conducting ]. We hear is the sound.

Q: Frequency converter OC alarm, what's the matter?: The frequency at which the OC fault occurs in all faults of the inverter may be the highest and the most frequent. In the process of starting the alarm, in the process of stopping the alarm, alarm in operation, so that power on the alert, and even with other fault codes or currentIndirectly tell you that there is a OC fault in this inverter!
