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: What's the frequency converter for? What does it look like?: Frequency converter (Variable-frequency, Drive, VFD) is the application of frequency conversion technology and microelectronics 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: The frequency converter is in use suddenly the speed reduces, then the debugging is out of control, how to do?: Overvoltage prevention measures: due to over-voltage causes are different, so the countermeasures are not the same. For overvoltage in parking, if there is no special requirement for parking time or position, it can be solved by using extended frequency converter, deceleration time or free parking. The so-called free parking, that is, the frequency converter will switch off the main switch, so that the motor free sliding stop. If the parking time or parking position have certain requirements, then the DC brake (DC brake) function can be used

Q: What is the main function of the frequency converter on the machine tools?: CNC machine tool spindle drive system is also called the main transmission system, is to complete the main movement of the power unit part. The main shaft drive system is changed into the cutting moment and cutting speed of the tool or workpiece installed on the main shaft by the transmission mechanism, and the ideal parts are matched with the feed movement. It is one of the forming movement of parts processing, and its accuracy has a great influence on the machining accuracy of parts. Machine tool spindle drive and the drive is different, the machine spindle motion is usually rotation, unlike feed drive need wire rod or other linear motion device for reciprocating motion, NC cutter and workpiece by rotating the spindle and feed the cutting motion.

Q: How does the PLC process the inverter output signal?: 1. The analog signals of the converter (such as the 4~20mA signal) are received in the analog input module of the PLC (for example, the EM235 module)2, the input signal processing (32000 digital quantity into 50HZ frequency signal)3. Compare the resulting frequency signals with their own internal settings

Q: How do you understand the ramp up (descent) time of the inverter? Thank you!: The reverse is the drop time, or the 0 speed. Water pumps and fan motors are basically not required to change. If it is an emergency stop, it is usually 3 seconds (depending on the frequency converter and process requirements).

Q: Where is the frequency converter used?: From the industry application: 1, chemical, petroleum, electric power, municipal, mining, cement, water treatment and other industries, the main use of 380V/690V/6-10kv inverter, these industries have a large fan pump power, the original AC operation, high energy consumption, the use of inverter speed regulation can be obtained after large energy saving, so it is the the main users of the main high power converter

Q: What does the RUN key on the inverter mean? How do you use it?: According to the actual needs of the motor to provide the required power supply voltage, and then to achieve energy saving, speed control purposes, in addition, there are many inverter protection functions, such as over-current, overvoltage, overload protection, etc.. With the continuous improvement of the degree of industrial automation, inverter has also been widely used.

Q: I do mining equipment, recently I used ABB frequency converter to put into our equipment, but the problem of interference really gives me a headache! We have two pieces of equipment of SIEMENS S7-200 PLC, and is used in point to point protocol communication with each other, when the converter work PLC communication interference! There are monitoring equipment, converter work, there are a large number of snowflakes on the screen, simply do not see! Not even an internal phone! I've done well in grounding, but I still can't do it! Is there any master who can teach me a trick?: You can try using the following methods:Solution of interference caused by circuit coupling:The PLC and monitoring equipment are powered by isolated transformers.

Q: Delta inverter fault output which parameter is set?: Overvoltage overvoltage fault of inverter DC bus voltage on the tributaries. Under normal circumstances, the average DC inverter three-phase full wave rectifier after. If 380V line voltage calculation, the average DC voltage Ud= = 513V. 1.35 U line in the overvoltage occurs when the DC bus capacitor will be when the charging voltage to about 760V, inverter over-voltage protection action. Therefore, inverter, have a normal range of working voltage, when the voltage of the inverter is likely to damage more than this range, there are two types of common overvoltage.
