KXR Series – Highly dynamic AC servo system with maintenance-free absolute encoder

Planned Launch in 2027

The KXR Series is a modern AC servo system designed for highly dynamic positioning and motion control applications. The series combines high-performance servo technology with an integrated battery-free absolute encoder and EtherCAT communication. Thanks to high rotational speeds, fast control response, and precise encoder technology, the KXR Series is particularly well suited for robotics, packaging machinery, conveyor systems, and demanding multi-axis applications.
