UIM2852CA is a NEMA#11 (28x28mm) all-in-one subminiature smart servo stepper motor designed for servo stepper motors, featuring a CAN Bus interface and Absolute Multi-Turn Encoder. 

These controllers integrate several key functional modules: Communication Unit / Motion Control Unit / Motor Driver / Feedback Control Unit / Input Logic Control and DSP System (for processing instructions, replying, notifications, coordinating other functional modules, executing preloaded user programs, and providing real-time status updates)

The major control loop is executed within 1 millisecond, ensuring responsiveness.

Key Features:

• Absolute Multi-Turn Encoder, with internal rechargeable battery.
• High-Performance DSP System: Executes all control loops within 1 millisecond.
