Q:Can 220V use frequency converter to drive three-phase motor with 380V?: The use of motor, if the star is connected to the corner of the connection can be, and if it is angle, then there is no way, and then the power of the motor will be reduced by about 4/10.

Q:What are the key points of frequency converter maintenance?: 1., regular cleaningAlways check the frequency converter regularly and keep the environment clean and dry. It is strictly prohibited to place sundries near the frequency converter, and someone should regularly clean the frequency converter, blow it out, keep the cleanliness of the converter and the ventilation of the air duct.2. treatment methodsIf it is found within the inverter or radiator plate dust and debris falling into, should promptly use compressed air to blow off. Clean air filter, cooling air duct and interior dust. When it is found that the conductor and insulator have corrosion, it should be promptly cleaned with alcohol.For continuously running inverters, the running state can be visually checked from outside. Periodically inspect the converter and check if there is any abnormality when the converter is running. The following tests should normally be carried out:

Q:How can I control the frequency converter with a computer?: Variable frequency speed control has been applied in the industrial field as the main means of AC motor speed control is very extensive, it has a wide speed range, steady speed and high precision fast dynamic response for a wide range of technical performance and reliable operation, has gradually replaced the DC motor speed control system. There are three main control modes of inverter: 1. through inverter panel operation, that is through the operation panel to change the output frequency and other operating parameters; 2. in the frequency converter analog input 0 ~ 10V or 4 ~ 20mA signal, by changing the size of input analog control of inverter output frequency converter; 3. through communication port (for RS485 control). The first method is generally used for manual adjustment and parameter setting on the spot, and the latter two are mostly used for automatic adjustment and remote control.

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:The difference between soft starter and converter: The soft starter is just a thyristor pressure regulating device is simple to start the motor, the motor speed can not be normal, low price; inverter is the AC power supply voltage and frequency, can IGBT chopper can be used to start the motor, can also be normal speed, the price is relatively expensive

Q:Which country invented the inverter?: Since 1960s, thyristor and its upgrade products have been widely used in power electronic devices. But its speed performance is far from meeting the needs. In 1968, the high-tech enterprises represented by Danfoss began to batch produce frequency converters and opened a new era of inverter industrialization.The beginning of 1970s, PWM VVVF (PWMVVVF) speed research get breakthrough, in 1980s after the microprocessor technology is perfect makes the algorithm easier to achieve.In the middle and late 1980s, VVVF converter technology in developed countries, such as America, Japan, Germany and Britain, was practical and the products were put into market and widely used. The earliest converters could have been bought by British and developed by British patent. However, the United States and Germany, with the advantages of electronic components production and electronic technology, high-end products quickly seize the market.Entered in twenty-first Century, the domestic inverter gradually rise, has gradually seize the high-end market. Shanghai and Shenzhen to become the forefront of domestic inverter development, emerged as Huichuan inverter, inverter, AMB inverter, frequency converters and a number of well-known domestic inverter. The AMB inverter was established in 1998, is one of China's first production of inverter manufacturers. Over the past decade, as the cornerstone to AMB rich cultural heritage, to support growth, enterprise quality system ISO9000 TUV earlier passed the certification, was awarded the "national high tech enterprise", has been appraised as "China user satisfaction of the ten domestic brands inverter".

Q:Frequency converter OC alarm, what's the matter?: I guess the original intention of the inverter circuit designer is this: when the power test module has broken down, or the operation of the module endangering the safety of the module, even the module has been damaged, it will promptly report the OC fault. The cause is generally a load side, a short circuit or a heavy loadThe load causes excessive overcurrent, or over current or even short circuit due to bad drive or damage of the module itself.

Q:If you don't plug in the PG card, do you use PLC's PID control?Plug in the PG card and the PLC PID control, which is reliable and precise?: If there is a PLC encoder as a speed sensor signal, you can access the PLCPLC analog output (or communication) as a given value of the inverterUse PLC's PID instruction to complete the speed closed loop control of the converter.Note: if you are not using vector control of the inverter, you can.For example: horizontal transmission of non vector control or pump fan class.

Q:What are the differences between the two quadrant and the four quadrant of the inverter?: Simply put, the two quadrant ordinary inverter can only drag the motor forward or reverse. Work in one and three quadrants. The kinetic energy of the motor idle time can only be wasted. (of an electric motor)

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.
