Yaskawa Electric Corporation SRC2 Servo Controller

The Yaskawa SRC2 MAX 400VA servo controller is a compact, closed-loop drive designed to regulate AC servo motors in industrial automation, including Yamaha/Yaskawa robotic systems and CNC setups. It provides up to 400 VA of output power with 100–120 VAC control power, and it drives motors at typical output voltages of ~200–400 VAC while using encoder feedback for precise position, speed, and torque control. This SRC-series controller is intended for panel or control cabinet mounting and supports either passive cooling or fan-assisted cooling depending on the model, making it suitable for robotics, CNC machinery, and precision automation requiring reliable, continuous operation. Common replacements include Yaskawa SRCA-2 MAX400 servo drive and Sigma-II (SGDH series), as well as Sigma-5 / Sigma-7 systems for modern upgrades.
