Q: Why does the frequency converter cause interference?: Shielded interference source: shielded interference source is an effective way to suppress interference. Usually the inverter itself with iron shielding, can not let the leaked electromagnetic interference, but the output line frequency converter is best to use steel shielding, in particular to an external signal (4~20mA signal output from the controller) control of inverter, the control signal line is as short as possible (usually less than 20m), and must use the shielded twisted pair and the main power line and the control line (AC380) and (AC220V) completely separated. In addition, the circuit of electronic sensitive equipment in the system also adopts shielded twisted pair, especially the pressure signal. All signal lines in the system must not be placed in the same pipe or slot as the main electrical line and control line. To make the shield effective, the shield must be grounded reliably.

Q: That is, some parameters of the inverter, such as torque, current, frequency, etc., are displayed on the Kingview software interface, but not through the PLC. The idea that the MODBUS protocol between SIEMENS and 200PLC has never been successful before, so that's the idea of the ABB. If it can be achieved,Is it necessary to write the script program on the Kingview, and what problems should I pay attention to when using the MODBUS protocol in Kingview software?The problem is a little bit more, I hope the experts teach me this rookie! Thank you: As long as there are 485 communications can be, the frequency converter manual on the MODBUS protocol, the address of each parameter, in the king view on the link can do, and I hope to adopt.

Q: How does the frequency converter change the voltage and change the speed of the motor?: The frequency converter regulates the speed of the motor, mainly by changing the frequency. The frequency determines the synchronous speed of the motor, and the speed of the motor can be lowered by reducing the frequency.

Q: Where is the difference between soft starter and converter?: Are two completely different uses of the product. The inverter is used for the need for speed place, its output voltage and frequency change not only change; the soft starter is actually a regulator for motor starting, output voltage and frequency change not only change. Inverters have all of the soft starter functions, but they cost much more than soft starters and have a much more complex structure.

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: Why does harmonic generator produce harmonic? What's his working principle?: The harmonic generation mechanism of frequency converter is because of the non-linearity of frequency converter, including two parts: rectifier and inverter. For a simple example, the streams we see are, if there is no wind, and the bottom is flat, then there will be no waves, no ripples. This is because the water flows through the region is linear. Because of the fact that the wind and the water are not flat enough, these nonlinear conditions lead to waves and ripples.

Q: What is the difference between SIEMENS inverter and built-in filter?: There is no built-in filter converter in the price slightly lower, mainly used in the equipment efficiency (power factor) requirements are not high, anti-interference ability requirements are not strict place;The frequency difference with built-in filter is mainly to the requirements of different electrical parameters in specially designed, can improve equipment (power factor), has the good anti-interference ability, prevent the transient surge of inverter module impact, has a good protective effect.

Q: What are the possible causes of frequency hopping overload?: Because the overload is judged only by the current, it will happen at the start, stop, acceleration and deceleration, and constant speed operation. Moreover, the current and the asynchronous motor difference are inseparable, so the following conditions can be used for analysis and reference:

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: What is the frequency converter AVR?: Automatic adjustment function: AVR voltage inverter based on voltage feedback, automatically adjust the output voltage, which is not affected by the grid voltage and load change, to protect the motor from excessive voltage caused by long-term insulation damage or high magnetic density caused by excessive heating core.
