Automatic blister edge bending machine.What should be done if the frequency converter of the ultrasonic embossing machine malfunctions?

　　With the continuous improvement of scientific skills, the birth of new high-power power electronic components, the application of integrated circuits and microcomputer skills, and the increasingly perfect and sophisticated communication frequency conversion and speed regulation skills.

　　The communication frequency converter speed regulation system has been widely used in professions such as metallurgy, petrochemicals, power, machinery, and civil appliances due to its advantages of wide speed regulation scale, fast dynamic response, high speed regulation accuracy, complete protection functions, and simple operation.

　　After 6-10 years of normal operation, the frequency converter is in the high-frequency stage of faults, often experiencing component burning, faults, and frequent operation problems, seriously affecting the normal operation of the frequency converter.

　　In the long-term maintenance and operation of equipment, I have encountered many different frequency converter faults. During the equipment maintenance process, I found that the fault categories have specific commonalities and regularities.

　　In actual maintenance, as long as the characteristics of the frequency converter are grasped, the maintenance work of the frequency converter can be done well, and various faults that occur in practice can be promptly dealt with and the service life of the frequency converter can be extended.

　　According to the requirements of frequency converter application technology, it is very important to develop and improve the daily protection methods and maintenance cycles of frequency converters, so as to prevent them from malfunctioning during initial use, especially in harsh environments.

　　In addition, professional repairmen have a thorough understanding of its principles, structure, and control methods.
