Product Display
Dual-Encoder Feedback and High-Precision Closed-Loop Control
Equipped with a dual-encoder feedback system, the joint actuator accurately monitors joint position and motion status. It helps compensate for transmission-chain errors, improving positioning accuracy and motion stability for precise robotic joint control.
Multi-Mode Servo Control
Supports multiple control modes, including force-position hybrid control, servo position control, servo speed control, and current (torque) control. The flexible control options accommodate different robotic joint requirements for position, speed, and torque regulation.
Adaptive Control and High Dynamic Response
Featuring adaptive control technology, the module adjusts its control response to changing loads, reducing the need for frequent manual parameter tuning. High control bandwidth supports fast dynamic response for smooth and responsive robotic joint motion.
Comprehensive Protection and Operational Safety
Featuring over-temperature, over-voltage, and overload protection, the module helps protect the drive system and related components under abnormal operating conditions, enhancing operational reliability in robotics and automation applications.
