Overview
The Yaskawa SGDB-10AN is a servo amplifier of the Σ series (SGDB series) for 200 V servo motors in the 0.85 kW power range. The AN variant combines the standard 200 V supply (“A”) with the digital MECHATROLINK command interface (“N”). The device is frequently used in CNC machine tools, precise automation axes, and handling systems where high reliability and digital bus communication are required.
