Q: Frequency converter, fault, contact action: Frequency converter is the application of frequency conversion technology and micro electronics 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: When the inverter is running at full 50HZ, the output voltage decreases and the output current becomes smaller. What is the reason?: If the load of the motor is increased, the slip S is increased, the electromotive force of the motor is decreased, and the electric current of the motor will become larger. That is to say, when the motor is running in the overclocking stage, the load of the motor is light, the current will become smaller, and the current will not be smaller if the load is negative. Didn't I make myself clear?

Q: The functions of frequency converter and UPS are similar, especially the power frequency UPS?: The obvious difference between the two:1, the former output amplitude and frequency adjustable, the latter output is a single fixed amplitude, frequency;2, the former does not use batteries, and the latter requires batteries.

Q: How can I learn the converter well?: Secondly, you can also take part in some frequency converter, PLC training institutions, in order to improve themselves, through training to enhance their skills, this is a way to quickly learn.

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: What is the upper and lower limit of the environmental temperature to ensure the normal operation of the inverter?: General environment temperature: inverter is an electronic device, containing electronic components, electrolytic capacitors, etc., so the temperature has a greater impact on its life. The environment of general inverter operating temperature of ~+50 DEG C - General requirements, if it can reduce the operation temperature of inverter, prolongs the service life of the transducer, stable performance. So heat dissipation is very important.

Q: There is much dust and moisture in my workshop. Many brands are not durable.: You can't do anything like this! Dust will fall on the circuit board and cause short circuit of the component. The same humidity.Suggest to strengthen the protection level of cabinet. But heat must be taken into account. Or make an independent electrical room. Install air-conditioning. As God offered!

Q: Is the voltage low? The younger brother is bored to death, no problem with the wire drawing machine, the full load will jump off. Display frequency converter overload and acceleration operation overcurrent. Help me please.: The difference between the display value and the measured value shows that the bus detection circuit is abnormal if the deviation is larger. Conversely, if the two value deviation is minimal or equal, the missing phase signal is abnormal. At present, there are two kinds of bus detection circuit used in our company: resistance voltage divider and operation comparison amplification (TL082). Corresponding to the detection circuit output 0 - 3.3V corresponds to the actual bus 0 - 1000V, the two circuits are relatively simple, maintenance only need to test the key point voltage in the circuit, you can easily find the fault point.

Q: I would like to ask vector control of the frequency converter, how the motor does not turn. What parameters are set up: No PG vector control (motor with encoder), set the motor parameters self-learning, rated voltage, rated current, fundamental frequency (50, 33.3, 20 HZ motor should pay attention to what kind of), pole number, frequency speed, rated power, the maximum output frequency, etc., set the end after the rotation form self-learning (motor without load), or stop shape self-learning. Even the self-learning control model parameter to the external terminal control, analog voltage is changed to external control, can be CNC, PLC or PC to control its operation.

Q: How to choose frequency converter?: 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.
