Key Electronic Components & Features #### A. 20-bit Optical Encoder The "R2" designation indicates the inclusion of a high-resolution absolute/incremental encoder. * **Resolution:** It provides 1,280,000 pulses per revolution. * **Function:** This allows for extreme positioning accuracy and smooth rotation at low speeds, which is critical for CNC and robotic arms. #### B. Permanent Magnet Synchronous Motor (PMSM) The motor uses high-grade permanent magnets on the rotor. Unlike induction motors, this electronic design ensures: * High power density (small footprint for high torque). * Low rotor inertia, allowing for rapid acceleration and deceleration. #### C. Integrated Safety & Protection (CE Marking) The `/CE` suffix indicates compliance with European Union safety standards. Electronic protections include: * **Overcurrent Protection:** Prevents winding damage during stalls. * **Overvoltage Protection:** Guards against regenerative energy spikes. * **Thermal Sensors:** Embedded sensors to prevent overheating. --- ### 3. Connection Interface The motor interfaces with the **ASD-A2-0421-M/F/L/U** series servo drives using the following connectors: 1. **Power Cable:** Supplies U, V, W, and Ground (G) phases to the stator windings. 2. **Encoder Cable:** A dedicated shielded cable to transmit high-speed differential signals back to the drive for closed-loop control. --- ### 4. Typical Applications Due to its 400W power rating and high-speed capability, it is commonly found in: * **SMT (Surface Mount Technology) machines.** * **Packaging equipment.** * **Medical imaging tables.** * **Laser cutting heads.**
