eRob110T Robotic Joint Actuator

The eRob T-type joint module is a highly integrated all-in-one robotic actuator that combines eight core components, including a servo motor, high-precision harmonic gear reducer, dual absolute encoders, servo drive, friction brake, temperature sensor, and virtual torque sensor. This compact and innovative design eliminates the need for complex external component selection and integration, providing a plug-and-play solution that simplifies robotic system development. It is ideal for high-performance collaborative robots and humanoid robots.

The built-in servo driver supports multiple industrial communication protocols such as EtherCAT, CANopen, and Modbus, ensuring seamless integration with various control systems. It allows real-time adjustment of position, speed, and current loop PID parameters, delivering precise and responsive motion control.

• Supports EtherCAT, CANopen, and Modbus communication protocols

• Real-time adjustable position, speed, and current loop PID

• Built-in ±10V analog input

• Supports pulse and direction control, I/O, and RS485 communication

• Compatible with external encoder and STO (Safe Torque Off) interface

The module features a built-in dual absolute encoder system that enables dual-loop position control, improving motion accuracy and stability. The output shaft is equipped with a 19-bit absolute multi-turn encoder for precise position tracking.
