Frequency converter is an indispensable equipment in modern industry. It is very important to master the principle and operation skills of frequency converter to improve work efficiency and quality. This paper will introduce the theory and practice of frequency converter, as well as the skills of rapid advanced and after-sales maintenance.

Theory and Practice Qi Fei.

The theory and practice of frequency converter are equally important. The teacher will deeply explain the parameter significance, working principle and control method of the inverter, and be familiar with the operation instructions. Practice links need constant debugging, accumulate experience, and let the inverter listen to your command!

The road to rapid promotion

Participating in professional inverter and PLC training is a shortcut to quickly improve the skill level. Here is the only way for you to become a master of frequency converter!

Maintenance after-sales service is essential.

Maintenance or after-sales personnel must master the main circuit diagram of inverter, including rectification, filtering, inverter and other links. Electronic components such as varistors and charging resistors are also well known. Especially, the function and pins of optocoupler in driving circuit, such as 250 and 350, must be familiar with. It is very important to judge whether the equipment is good or bad during maintenance!
