Improved machine design. Increased machine productivity

Designed to meet the machine requirements, the 1S servo technology optimizes the full cycle, through the machine design, installation and commissioning tasks and finally to the maintenance once in production. In addition to the traditional motion solution, the 1S servo offers high-resolution multi-turn encoder without battery backup, safety network built-in and improved loop control allowing accurate and higher machine productivity.
