The ASDA-M series servos go beyond the single-machine thinking mode, and the three servos are integrated in the same frame. There is no time delay for exchanging data between the axes. The function of the built-in small PLC is simple. 
Q: In order to adapt to the fierce competition in the market, the major companies are getting shorter and shorter. For example, the production of cosmetics can generally be changed in three years, even in a quarter, and the production volume is relatively large. Therefore, the flexibility and flexibility of packaging machinery are very high: the life of packaging machinery is far greater. In the life cycle of the product. How does servo control respond to this demand from the packaging industry for packaging machinery? Among them, what kind of help should machine vision play? 
Zhou Ruihua: Delta servo has built-in various functional modules with flexible adjustment space. The flying shear curve can be modified online. It also has color mark correction function, high-speed grabbing and comparison function, cam alignment function, which can be very good. Phase correction, air defense and anti-cut processing, automatic film handling, and only need to change the cam online for different packaging types. Excellent servo characteristics and built-in complete packaging machinery control solution can not only meet the diversified production requirements of packaging machinery, but also achieve high speed, high precision packaging, less material waste and high production efficiency. 
Machine vision is a sufficient condition for the realization of packaging machinery and high-precision packaging, especially in industries with high finished products, such as the pharmaceutical packaging industry, the requirements for detailed inspection are very high. Delta has developed the DMV machine vision system for this demand in the pharmaceutical industry.
