As a strategic industry for producing industrial mother machines, equipment manufacturing is not only a touchstone for testing industrial technological innovation, but also an arena for various types of mechanical equipment. Nowadays, under the guidance of new quality productivity, the equipment manufacturing industry is accelerating towards high-end, intelligent, and green development, injecting a continuous stream of strong momentum into China's new industrialization construction.
Schneider Electric has always been deeply engaged in the field of industrial automation technology innovation. In recent years, it has continuously increased its investment in research and development and local innovation in China. With the completion of the upgrade of Schneider Electric's IA China Hub and the launch of the Wuxi Automation R&D Center, the industrial automation product family created by the company for the high-quality development of the equipment manufacturing industry is growing stronger and richer. Among them, the representative one is the recently launched all-new Lexium 18 series servo.
As the first servo product developed by Schneider Electric's local team in China, the Lexium 18 series servo products not only maintain the traditional advantages of "European servo" in technology and performance, but also have the advantages of "Asian servo" in ease of use and flexibility, which can significantly improve the experience of equipment manufacturing enterprises in precision, reliability, convenience and ease of use, and help enterprises achieve efficient and high-quality development.
Specifically, whether it is the Lexium 18E bus type servo drive that supports the EtherCAT bus protocol or the Lexium 18P pulse type servo drive that uses pulse mode, paired with BCH18 and BEH18 series motors, equipped with features such as adaptive resonance suppression, end vibration suppression, dynamic braking, STO safety function, etc., it helps enterprises achieve more precise, efficient, stable and reliable production. Users can use optimized self-tuning functions to achieve precise and convenient adaptive matching device debugging, thereby saving 2/3 of installation and debugging time. At the same time, the Lexium 18P pulse type servo supports internal script programming, which can easily meet users' more customized functional needs. For users with mass production needs, the servo parameters of the same model can be easily copied to other machines, achieving faster "plug and play". In addition, the Lexium 18 series servo adopts a Type-C debugging interface, which not only connects to a laptop for debugging but also takes into account the power supply function. Compared with the traditional Mini USB debugging interface, it reduces the additional wiring used for power supply and further optimizes usability.
At present, Schneider Electric's Lexium 18 series servo products have passed the test of hundreds of customers from multiple industries such as electronics and electrical engineering, packaging, and material processing, and have been successfully applied to more than 100 types of equipment, helping enterprises stand out in competition and providing key support for the transformation and upgrading of the equipment manufacturing industry.
