Q:Why do you install these things? Our factory has 380220 points. Then we plant in addition to high voltage motor, the other are 380 of the motor, then what's the use of these two things?: The frequency changer changes the frequency of alternating current. The transformer changes the voltage.Take a closer look at the materials on the electrician.

Q:What does the RUN key on the inverter mean? How do you use it?: When selecting panel operations (when the panel of the inverter is the control source of the inverter), it is the meaning of the "running" button.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 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. The inverter adjusts the voltage and frequency of the output power by disconnecting the internal IGBT

Q:Which country invented the inverter?: The frequency converter is the electric energy control device that transforms the power frequency power to another frequency by the on-off function of the power semiconductor device.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.PFC is the term "power factor", which is mainly used to characterize the efficiency of electronic products in the utilization of electric energy. The higher the power factor, the higher the efficiency of power utilization.

Q:The functions of frequency converter and UPS are similar, especially the power frequency UPS?: 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.UPS is an uninterruptible power supply, including an energy storage device, a rectifier, inverter as the main component of the regulator, frequency stabilized AC power supply. The main use of battery energy storage power supply device to provide uninterrupted computer / server, storage equipment, network equipment, computer communication network system and industrial control system, need continuous operation of industrial equipment in power outages. When the power input is normal, UPS electric voltage supplied to the load, the UPS is an AC electric regulator, it is also to the storage device such as a battery charging; when the power interruption (outage), UPS immediately to the storage device (such as batteries or fly wheel the electric energy storage system), continue to supply alternating current to the load by the method of inverse transformation, the load to maintain normal working and protect the load of software and hardware is not damaged.

Q:What's the use of switching frequency of converter?: Switching frequency is generally the default value of the system is better, do not recommend any adjustments, generally only when problems are encountered, will be adjusted, because:The higher the switching frequency of the converter, the smoother the output waveform; the lower the switching frequency of the converter, the worse the output waveform. Switching frequency, to put it bluntly, is chopping, assuming we cut the sine wave for 100 and 1000, and that must be the combination of 1000 segments, the waveform is more like a sine wave, this should be understandable.

Q:What does "EPCU" mean in a frequency converter?: This is the frequency converter BlueOcean Huateng, they said this code external signal interference, you are not the power line and the signal line to go ah, check the external line, then no problem on the phone to the factory

Q:What are the differences between the two quadrant and the four quadrant of the inverter?: For a motor alone, the so-called four quadrant refers to its operating mechanical characteristics curve, on the mathematical axis of the four quadrants can run. The first quadrant is in the positive electric state, the second quadrant feedback braking state, the third quadrant reversing electric state, and the fourth quadrant reverse braking state. A frequency converter that makes the motor work in the four quadrant is called the four quadrant converter.

Q:What are the precautions for frequency converter wiring installation?: The control signal line should not be parallel to the power line. If parallel must be used, the shielding wire and one end of the earth must be used.To use 485 or 232 communication, wear a magnetic ring and use twisted pairs.

Q:Can the motor with frequency converter directly wave the insulation?: Frequency converter with motor, is a high-power three stage tube, C, E in the output, you directly shake insulation, measuring the pressure of the transistor. So you can't measure it.

Q:Schneider 303 4KW frequency converter F 013 trouble shooting method: You see when the alarm is started, or stable operation alarm amount, different times, different analysis
