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: I am in control of the equipment: the same mechanical movement, this needs a motor drive, a frequency converter drive. Now it's due to the mechanical location: buy two units of the same motor. Can you use a converter in parallel to drive it? Please point out! Thank you (frequency converter: the power of Schneider is equal to the sum of two motors): It is possible to control more than one motor with 1 inverters, which are controlled by the transmission track motors in general metallurgical projects, but should pay attention to the following points before operation:1 the choice of inverter power (the power converter must be greater than or equal to the sum of the motor power)2, the choice of control mode (usually with VF control, no speed feedback open-loop control)3 parameter settingsA sets the current value of the motor to the sum of the current values used by all motorsB sets the voltage and frequency of the motor, which is the voltage and frequency value of an electric motor

Q: What does 0L1 stand for?: Inverter 0L1 stands for frequency converter fault code: OL1: motor overload (OL1) fault for the output current exceeds the overload capacity of the motor, then need to reduce the load.

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: What's the function of this brake unit?: When the motor is fast stopping, the motor will feedback the energy to the converter, causing the DC bus voltage to rise or even damage the IGBT. Therefore, it is necessary to use the braking unit to save the part of the energy to protect the converter.Inverter braking a lot, can refer to:

Q: What is the frequency converter AVR?: When the input voltage deviation from the rated value, the function can keep the output voltage constant, so under normal circumstances should be AVR action, especially when the input voltage is higher than the rated value, to protect the motor from excessive voltage caused by long-term insulation damage or high magnetic density caused by excessive heating core.

Q: How do you set the frequency with panels?. What are the specific steps?: 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.

Q: What is the working principle of a three phase AC asynchronous motor inverter?: Distance determination of frequency converter and motor, cable and wiring method;The distance between the I. converter and the motor should be as short as possible. This reduces the capacitance of the cable to the ground and reduces the interference of the transmitter.II. control cables use shielded cables, power cables use shielded cables, or from frequency converters to motors, all shielded by threading tubes.The III. motor cable shall be independent of other cables, with a minimum distance of 500mm. At the same time, it is necessary to avoid the long distance parallel wire between the motor cable and other cables, so as to reduce the electromagnetic interference caused by the rapid change of the output voltage of the inverter. If the control cable and the power cable cross, as far as possible so that they cross at 90 degrees angle. The analog signal line associated with the inverter is separated from the main return line, even in the control cabinet.IV. and inverter related analog signal line is best to use shielded twisted pair, power cable shielded shielded three core cable (its specifications than ordinary motor cable large files) or comply with the frequency converter user manual.

Q: What do you mean by the capacity of the inverter and the capacity of the motor?: Capacity can be understood as active power + reactive power, such as the capacity of 100KVA inverter, is not 100KW motor,

Q: What does "G" and "P" mean in the converter model?: General inverter said, "G" and "P" type refers to the inverter general type and fan pump difference, G type inverter applies to the general machinery class load, and P type is used in the wind or water pump.
