Q:How does frequency converter realize variable frequency speed regulation?: V=60f/nvMotor speed fFrequency nMotor poles without frequency converter to change the motor speed, only by changing the pole of the motor to achieve, frequency is 50HZ; through the inverter to change the motor speed is running frequency, no need to replace the motor can realize the speed control. The principle of speed regulation is the formula above.

Q:Which brand of converter is better?: Shanghai Leinuoer recommended! Soft starter and frequency converter products Shanghai Leinuoer company, national key products, Shanghai famous trademark! People's Insurance Company of China quality assurance! Shanghai World Expo Shanghai reyrolle company supporting the project, the Beijing Olympic Games project,

Q:What is the difference between frequency converter and servo driver?: The difference between servomotor and frequency conversion motor:Servo system is a closed-loop control system, the inverter usually works in open-loop control, so in terms of speed and accuracy, and can not be compared to the servo drive.The frequency conversion is only one part of the servo, and the servo controls the closed loop precisely on the basis of frequency conversion so as to achieve better results.

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:Delta inverter fault output which parameter is set?: Overload overload fault include frequency overload and overload. The electric machine may be accelerated in short time, the DC brake is too large, the grid voltage is too low, the heavy load causes. Usually by extending the acceleration time and prolong the braking time, check the power voltage. The heavy load, the motor and inverter can not drag this may be due to mechanical load, lubrication is not good. The former must replace high power motor and inverter; if the latter want to overhaul production machinery.

Q:I would like to ask, the inverter in use in the grid is very high?: Yes, because the harmonic generated by converter works has certain influence on the quality of power grid, so the demand for power grid is higher. 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 adjusts the voltage and frequency of the output power by the breaking of the internal IGBT. According to the actual needs of the motor, it provides the required power supply voltage, and then achieves the purpose of energy saving and speed regulation,

Q:Frequency converter OC alarm, what's the matter?: And some did not inform you of the inverter fault category, when the OC boot failure, will cause greater danger, then simply caused by surface phenomenon similar to program crashes, such as the P9/G9 series machine when the machine detects INVT, module failure, operationThe H00 character appears on the panel, and all key actions are rejected. Unknown insider will think: program crash, CPU motherboard is a problem.

Q:What does "EPCU" mean in a frequency converter?: This code indicates external signal interference.It is possible that the power line and the signal line are coming together to check that the ground of the converter is ready.If not yet, that can only be considered in the inverter output end of the inverter output filter, or inverter output reactor to try.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.

Q:Ask, what is the ratio of frequency converter?: Rotating main potentiometer, respectively, to see the three frequency converter F1.00 parameters, keyboard digital display reference input, follow potentiometer changes, and the proportion of 1:1.5:2. Rotate three trimmer potentiometers respectively, and the reference input of the corresponding converter has little change.

Q:Where is the frequency converter used?: The machinery manufacturing industry, including: elevator, automobile, textile, printing and packaging, paper making, hoisting machinery, food, tobacco, etc. the use of these pumps, inverter industry is mainly in electrical equipment, control and obtain the best product performance and output rate is the main purpose of energy saving is different from the 1 in
