Yaskawa Electric Corporation SGDV-R70A21AY817AA Servo Drive Amplifier

The Yaskawa Electric Corporation SGDV-R70A21AY817AA servo drive amplifier is a Sigma-5 servo drive designed to power Yaskawa servo motors for high-performance motion control in CNC machines and automated production lines. It supports fast response and precise multi-axis coordination in applications such as CNC machining centers, industrial robots, and packaging lines, with a panel-mounted drive configuration for easy integration. Key specifications include ~7.0 kW rated output, 200–230 VAC, 3-phase input, and control modes for position, speed, and torque, plus MECHATROLINK / analog-pulse communication (model-dependent) and high-resolution encoder feedback. Compatible with Yaskawa Sigma-5 servo motors, it is used for repair, retrofit, replacement, or upgrades to optimize machine performance in industrial automation systems. Condition: New / surplus / refurbished; Status: Active / supported component. Common replacements include Yaskawa SGD7S-R70A, SGDV-7R6A, and SGDH-75DE servo drives.
