Q:What is the frequency converter AVR?: Automatic adjustment function: AVR voltage inverter based on voltage feedback, automatically adjust the output voltage, which is not affected by the grid voltage and load change, to protect the motor from excessive voltage caused by long-term insulation damage or high magnetic density caused by excessive heating core.

Q:What's the frequency converter for? What does it look like?: The inverter is mainly used in industrial equipment, such as power plants, water plants, water supply equipment, large pumping station, it is basically a cuboid, a digital display control panel; and in the English show types into the universal type, fan pump type, vector control, different types should be used in different working conditions, voltage grade from 220V-10 million volts.

Q:What are the modes of operation of a frequency converter?: If the inverter is still protected within a specified period of time, the running curve of the starting P should be changed, from the straight line to the S, U, or reverse, S, and U lines. When the motor load is large, a longer start stop time should be adopted, and the operation curve type should be set according to its load characteristics. 41 If the inverter is still running failure, try to increase the maximum current protection value, but can not cancel the protection, there should be at least 10% to 20% of the protection margin. 51, if the frequency converter operation failure or replacement, should be replaced by a larger power converter. 61 If the inverter drives the motor in the start-up process can not reach to the preset speed, there may be two cases:

Q:A control panel I received a photoelectric switch, through the 232 interface connected to the computer, control with a 220V power supply board, computer and inverter when the inverter after the start of the photoelectric switch either do not work or turn off the flash chaos, frequency converter or 232 line open photoelectric switch will be back to normal work. In addition, when the photoelectric switch is powered separately, if the ground wire is connected to the control board, the photoelectric switch does not work. Excuse me, is this interference from the power cord? How to solve?: A) PE inverter main circuit terminals (E, G) must be grounded, the motor can be grounded and the inverter with the common ground, but not with other equipment, must play ground pile, and the ground should take place far away from electrical equipment. At the same time, the cross-sectional area of the grounding wire of the converter shall be no less than 4mm2, and the length shall be within 20m.(b) in the ground wire of other electromechanical equipment, the protective earthing and the work earthing shall be separately provided with grounding electrodes, and finally shall be imported to the electrical position of the distribution cabinet. The shield of the control signal and the shielding of the main circuit wire shall also be separately provided with earth electrodes, and finally shall be incorporated into the electrical junction of the distribution cabinet.

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: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:Application of ABB frequency converter: 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:What are the precautions for frequency converter wiring installation?: First understand the instructions, do not take the control line wrong, power line into the wire outlet is connected, you can debug it

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:Schneider 303 4KW frequency converter F 013 trouble shooting method: If the converter is overloaded, it is recommended to check the set acceleration time and whether the load is blocked or not.
