Lesson learned | What is the proper distance between the VFD and the motor?
The voltage waveform output by the frequency converter is only similar to a sine wave, but not a real sine wave. Its waveform contains a large number of harmonic components. It is well known that higher harmonics will increase the output current of frequency converter, cause motor winding...Read more -
Lesson learned | How to convert and process analog signals by PLC
Analog signal is the most basic input form of process signal (pressure, temperature, flow, etc.) in automatic process control system. The process signals in the system are converted into unified voltage and current signals through the transmitter, and these signals are transmitted to the control...Read more -

They are made by winding...Read more -
Lesson learned | Characteristics of three different loads of frequency inverter
How to select different frequency converters for load? If there is a special frequency converter for load, the special frequency converter shall be selected. If there is no frequency converter, the general frequency converter can only be selected. What are the three different load characteristics...Read more -
Why does the inverter crash after working for a while?
The machine crashed after working for a while. What’s the reason? Does the frequency converter have a fault code? If yes, check the manual. Most of them are over-current and undervoltage. If it is normal, the friction of the air-cooled inverter equipment may be large and the resista...Read more -
