Variable frequency drive applications

Due to variable frequency drive can adapt to various requirements in production process, especially in the industrial automation control applications, AC variable frequency control technology has risen to be the mainstream in industrial automation controls. AC variable speed system performance is almost same as DC speed control system, even exceed the DC speed control system. It adopts all-digital control ways to enhance information processing capabilities greatly. And integrate practical experience and skills into the software for complex control which can not be achieved by analog control, to improve variable frequency drive reliability, usability and maintainability. As variable frequency drive has good speed adjustment performance, wide speed adjusting range and high efficiency, easy operation, and communication with other devices, so VFDs are applied more and more widely. Over the years, we have practical applications in the production, and continuous learning, accumulate lot of variable frequency drive maintenance and repair experiences.
