Q: A control panel I received a photoelectric switch, through the 232 interface connected to the computer, control with a 220V power supply board, computer and inverter when the inverter after the start of the photoelectric switch either do not work or turn off the flash chaos, frequency converter or 232 line open photoelectric switch will be back to normal work. In addition, when the photoelectric switch is powered separately, if the ground wire is connected to the control board, the photoelectric switch does not work. Excuse me, is this interference from the power cord? How to solve?: Reasonable wiring: the concrete method has:The power line and signal line of the equipment shall be as far as possible from the input and output lines of the converter.Other equipment power lines and signal lines should be avoided parallel with the input and output lines of the inverter.If the above measures are not successful, then continue the following measures:

Q: 1, the frequency converter to the motor cable should be shielded cable? 2, whether there are specifications?: When we design the frequency converter to drag the motor load (mostly fan and water pump general machine), we should use shielded cable. We refer to the GB/T21209-2007 "inverter power supply design and performance of cage induction motors in section 9.1.4" guide "motor power cable" 9.1.4.1 "recommended configuration" in the "provisions of more than 30kW motor wiring should adopt the single core power cable or a plurality of grounding wire arranged symmetrical cable. Small power and suitable for wiring, priority is to use multi-core shielded cable." As the PE line symmetrical configuration of the 3+3 inverter dedicated cable, construction is always raised, not wiring, we later too lazy to explain, usually directly with the 3+1 type multi-core shielded cable. From the running situation, the effect is also good.

Q: How does frequency converter realize variable frequency speed regulation?: The frequency of the electric field is changed, and the frequency of the original fixed 50 Hz is reduced as required, and then the rotation frequency of the induction motor is changed

Q: Today, I was asked the question, and I also brought it to you to share the following Oh!: The frequency of the electricity we use everyday is 50Hz. If we want to change the frequency, we have to change it through the frequency converter.The working principle of frequency converter is to change the frequency alternating current into no frequency direct current, and then control it by electronic circuit so that it can adjust its frequency alternating current at any time.The inverter is similar to the back half of the inverter, which converts the direct current into alternating current.

Q: How do you understand the ramp up (descent) time of the inverter? Thank you!: That is, the frequency converter starts from the time it takes to set the upper limit. It can be said to be the acceleration time, which can be set in the parameters of the converter. Then, the deceleration time is just the opposite.

Q: What does "EPCU" mean in a frequency converter?: But look at your inverter has also been used for some time, if not before, and now appear, it is estimated that the hardware is broken, and manufacturers communicate maintenance!

Q: How much is the motor 90KW and the frequency converter selected?Colleagues suggest 110W?The cost will be higherIs it okay to choose 90KW?: Motor 90KW, frequency converter, 90KW can be applied, but the frequency can not exceed the rated value of the motor. There are some occasions to live and use the frequency converter to speed up the motor, so it should be chosen a little larger, otherwise the inverter will be more loaded.

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: What are the benefits of installing economizer in industrial enterprises?: The input and output filter and the DC reactor in the economizer can prevent the harmonic produced by the converter and cause the pollution of the power grid and the surrounding electricity environment.3 、 no disturbance power supply / electricity saving conversion system is beneficial to ensure that the customer load can be put into use quickly when the machine fails, and the normal production of the customer will not be affected. At the same time, the protection function of the economizer is perfect, and it has the protection function of over voltage, under voltage, over current, over temperature and surge resistance.4, reactive power compensation, improve the power factor of the system, reduce reactive power loss.

Q: What do you mean by the capacity of the inverter and the capacity of the motor?: Because the motor consumes active power and consumes reactive power, and the reactive power is also occupied, the motor with 70KW can only be usedThe power is known to everyone
