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 do you mean by the capacity of the inverter and the capacity of the motor?: Because the motor consumes active power and consumes reactive power, and the reactive power is also occupied, the motor with 70KW can only be usedThe power is known to everyone

Q:Why does the frequency change when the frequency converter regulates the frequency?: Main flux of motorM = U/ (4.44*f*N)In the upper model, the U is the stator voltage, that is, the output voltage of the inverter, f is the frequency, and N is the stator winding turn number.N is a constant.Obviously, when the frequency changes, if the voltage is constant, then the flux will change.The iron core of the motor is nonlinear, and when the flux changes, both too large (saturated) or too small (weak magnetic) is detrimental to the motor.Therefore, when changing the frequency, the voltage is changed, and the constant value of U/f is kept, so that the magnetic flux can be kept unchanged.

Q:What does the base frequency 60Hz represent in the inverter?: If the motor chooses a special AC frequency conversion motor, the motor is always marked with constant torque and constant power speed range. For example, Mark 5 ~ 100HZ for constant torque, 100 to 150HZ for constant power, the basic frequency should be set to 100HZ. The fundamental frequency parameter directly reflects the relationship between the output voltage and the output frequency of the inverter. If it is not set properly, it is easy to cause the overcurrent or overload of the motor. For example, an AC motor rated voltage 380V, rated frequency is 60HZ, if the frequency is lower than that of converter 60HZ V/F, a high proportion of the output voltage as high frequency, high output current, at startup, easy to cause the flow. If the frequency converter is set higher than 60HZ, low V/F ratio, the output voltage of the same frequency is low, the output current is low, at startup, can easily lead to the start and overload.

Q:1, the frequency converter to the motor cable should be shielded cable? 2, whether there are specifications?: 1, there are no special specifications, but each oneThe manual must have all the precautions required for good shielding.When the output of high frequency voltage pulse, the higher the frequency, the greater the external radiation interference. UseThe line is mostly blockedExternal interference.2, if there is no other equipment around (usually 5 meters as the boundary), then the shielded line can not be used, because there is no external interference.

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:What does a frequency converter do?: What is the starting current and starting torque of the motor when the inverter is in operation?Using frequency converter operation, with the acceleration of the motor, accordingly improve the frequency and voltage, the starting current is limited to 150% rated current (according to the type of machine is 125%~200%). The starting current is 6~7 times of direct starting with the mains frequency power supply, so the mechanical and electrical impact will be produced. It can start smoothly with frequency converter (longer starting time). The starting current is 1.2~1.5 times the rated current, the starting torque is 70%~120%, the rated torque; for the inverter with automatic torque enhancement, the starting torque is above 100%, and the full load can start.

Q:Knowledge, principle and operation method of frequency converter.: Basic classification of the working principle of frequency converter:Frequency converter working principle has been, so there are so many converters in the world for Mao is not the same? If you cry in this case, I can only say sorry, yes, but they can also do the classification (please open up the brain to process OCD pattern): classification according to the working mode of the main circuit, can be divided into voltage type inverter and current source inverter; switching mode in accordance with the classification, can be divided into PAM control inverter PWM control frequency converter and high frequency PWM inverter control; in accordance with the principle of classification, can be divided into V/f control inverter, slip frequency control inverter and vector control inverter; according to use classification, can be divided into general high performance frequency converter, inverter, high frequency inverter, single-phase inverter and three-phase inverter.

Q:What are the basis of the frequency converter to choose?: 1, brand, mainly for cost control2, performance, overload, function, reliability,3, load characteristics, constant torque, square torque or special load (determine the length of the cable of the load motor)4, environmental aspects: temperature, humidity. Altitude.These are the needs of attention when type selection.The last point is the most important, when choosing type, remember that the motor power can not be selected, must be selected in accordance with the motor current.

Q:What are the modes of operation of a frequency converter?: Frequency converter with motor no-load operation, 11 set motor power and pole number, to consider the work current of the converter. 21 set the maximum output frequency, frequency and torque characteristics of the inverter. VPf types include items such as maximum frequency, basic frequency and torque type. The highest frequency is the highest frequency that the inverter motor system can operate, because the highest frequency of the inverter itself may be higher, when the highest frequency allowed by the motor is lower than the frequency conversion
