Q: What does 0L1 stand for?: The acceleration is generally overloaded during acceleration. Load inertia is too large, the inverter power is small, or the acceleration time is too short, and so on

Q: What are the key points of frequency converter maintenance?: Selection of frequency converter and installation noticeType selection of frequency converter in general should pay attention to the matters (such as input supply voltage, frequency, output power, load characteristics and so on), also requires a good match with the corresponding motor requirements during normal operation, giving full play to the advantage of energy saving at the same time, to avoid the overload operation, and try to avoid dragging equipment such as pumps the inefficient work area, to ensure the efficient and reliable operation.The installation environment of inverter must try to be clean and dust, and has good ventilation environment, ventilation conditions can be considered the side wall at the bottom of the inlet exhaust, and the inverter is installed, the top and side shall be sufficient for the minimum cooling distance, inverter inverter heat dissipation, in addition, there are certain requirements the environmental humidity, high humidity, electrical insulation to reduce the inverter itself, bar metal parts easy to corrosion, and the humidity is too low and easy to cause insulation damage, generally keep the humidity between 40%-90%.

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: How does the PLC process the inverter output signal?: Depends on analog or switch volume, if it is analog, you can use analog input module, if it is the amount of switching, with ordinary IO on it

Q: There is a feed and send system. Now due to the severity of the material is not the same as the two converters often change speed, the workers do not understand their own, often by, often bad now how to use the best way you can use a potentiometer or other method, control of the two frequency converter, synchronous operation. Is to adjust one, and the other also with the kind of frequency, so that you can let the workers themselves to open, and the two inverters, the same manufacturer, the same model, the same load,: What kind of communication mode does the frequency converter support? Generally speaking, it is more accurate to communicate by means of synchronization. Expensive。The main transformer potentiometer, from the analog frequency converter, may be 1, the lag will be greater than 2, analog may have a larger error, 3, analog may be subject to interference. The cheapest。You can also use synchronous controller, analog input, the two roads as the same analog, cheaper, more reliable synchronization, may be disturbed.

Q: Today, I was asked the question, and I also brought it to you to share the following Oh!: Inverter inside the circuit is inverterIt is a control of communication -- direct current -- CommunicationDC alternating current is called inverter

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: The frequency converter works with sharp noises. What's the process of converting electrical energy into mechanical energy?. The mechanism of sound making. Thank you: 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: I would like to ask, the inverter in use in the grid is very high?: In the process of using inverter, grid voltage fluctuation requirements is not high, the general phase is to allow + 20% fluctuations, three-phase is allowed 15% fluctuations, so most of the grid voltage can be satisfied, unless it is in the countryside, or more remote areas, the voltage change will exceed the allowable value. In addition, the frequency converter on the power grid harmonics also have requirements, if the harmonic content of more than 20%, will lead to frequency converter misoperation, false alarm, more serious circumstances, will lead to inverter out of control, or damage. However, most of the current harmonics will not happen, unless a large number of individual factories use frequency converters, servo, intermediate frequency furnace, welding machine and other equipment.

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?: Using PG card of frequency converter to realize closed loop vector controlFor example, vertical motion loads, such as cranes and elevators, require closed-loop vector controlIn this case, the frequency converter must install the PG card, and the encoder signal will be connected to the PG card, using the frequency converterPID instruction.In this application, the PID function module of PLC can not realize the vector control function.
