Third generation of development

SE-S, which was released in 1997 and was the industry’s first machine equipped with the direct drive, instantly and solidly established Sumitomo’s all-electric technology.
The direct drive system symbolically represents the developmental philosophy of the all-electric technology and the wide range of the technical capabilities.
The direct drive directly communicates the required movements without going through unnecessary speed reducing devices between the servo motor and actuator. The drive has continued to evolve through enhanced low inertia moment and speed acceleration, and it is now in its third generation.
The performance has been significantly improving.
