YOKOGAWAe UD1CG3-004N-1AA-2SA-N/CNIt is designed to drive a direct-drive servo motor (zero backlash, high precision), with high control fidelity. It supports auto-tuning, precise servo control, and is used in applications requiring high torque, precise position, or velocity control, e.g. in robotics, semiconductor equipment, precision assembly, motion control, etc.<br />
The suffixes in the model name define options such as input voltage code, feedback or encoder type, braking or safety features, connector types, etc. The "CN" likely indicates “China / Chinese region / connector variant” or similar regional option.
