Yaskawa Electric Corporation SGDS-04A12A Servo Drive

The Yaskawa SGDS-04A12A servo drive delivers 0.4 kW of continuous output for precise, closed‑loop motor control in automated systems. Part of the SGDS Series (Sigma II) and designed for panel‑mounted installation, this drive uses digital servo control with an analog and pulse input interface to pair with Yaskawa Sigma II servo motors. It accepts 200 VAC class power and relies on forced air cooling for reliable operation in industrial environments. Typical applications include CNC machining centers, robotic cells, conveyor lines, packaging machinery, and assembly lines where synchronized motion, accurate speed control, and precise positioning are essential. Maintenance teams, OEMs, and system integrators often use the SGDS‑04A12A for repairs, retrofits, and motion control upgrades. Common replacements include SGDS-04A01A, SGDV-2R8A01A, and SGDA-04AS.
