Details

Built for robotics actuators that need high torque, high precision, and stable closed-loop control.

RS485 or CAN bus communication supports flexible integration with common robot controllers and drives.

Dual absolute encoders (motor + reducer) help retain the zero point after power-off for repeatable positioning.

Pin definitions make it easier to wire power and select RS485/CAN communication during integration.

The 1:10 planetary reducer is optimized for compact torque output in tight actuator spaces.

PC tool software supports parameter tuning, functional testing, and firmware upgrades during commissioning.

Multiple control modes and protection options support torque, speed, and position loop workflows.

Suitable for AGVs, robotic arms, quadrupeds, and wearable robot joints where precise gearing and feedback are required.
