Details

Built for compact robotics and automation joints, the L9030 series focuses on low-speed, high-precision control with a hollow-shaft form factor.

Premium core materials, an outer-rotor structure, and smooth bearings support stable operation, while multiple control modes cover torque, speed, and position.

Wide input voltage support and CAN/RS485 connectivity help simplify integration with PC, MCU, PLC, or industrial controllers.

Connector pinout and ID switch labeling make bus wiring and device addressing clearer during installation.

PC tools support parameter tuning, testing, and firmware updates, with encoder options available for different positioning needs.
