Yaskawa SGDH-04AE-OY Sigma II Series 400W Servo Drive
Product Overview
The Yaskawa SGDH-04AE-OY is a Sigma II series servo drive rated at 400W (0.4 kW) for 200 VAC input. It features MECHATROLINK-II high-speed motion network communication, allowing cascaded multi-axis control. This drive is ideally suited for precision positioning in CNC machines, pick-and-place robots, and general-purpose factory automation. The “-OY” suffix indicates specific firmware and connector options for OEM integration.

MECHATROLINK-II Network Integration
The SGDH-04AE-OY uses a MECHATROLINK-II interface for high-speed, real-time command and status exchange. This allows a single motion controller (e.g., Yaskawa MP2300) to control multiple axes in a daisy-chain configuration without complex wiring. Network cycle times as low as 0.5 ms enable synchronized motion for demanding applications like electronic camming and interpolation.
Advanced Servo Control Features
The Sigma II drive incorporates advanced auto-tuning, vibration suppression filters, and built-in electronic cams. The drive can store up to 32 motion profiles and execute them upon network commands, offloading the host controller. It also supports a unique “feed-forward” function to reduce following error during acceleration.
Connections and I/O
CN1 (MECHATROLINK): 4-pin RJ45
CN2 (Encoder): 20-pin connector
CN3 (External I/O): 8 inputs (servo-on, alarm reset), 4 outputs (ready, alarm, positioning complete), plus analog monitor
CN4 (Power): Main circuit and control power terminals
Industrial Applications
CNC milling and plasma cutters (feed axes)
Pick-and-place robots (gantry and rotary axes)
Automated guided vehicles (AGV) steering
Packaging equipment (flying knives, indexing conveyors)
Conclusion
The Yaskawa SGDH-04AE-OY Sigma II servo drive delivers high-performance motion control in a compact, network-ready package. Its MECHATROLINK-II interface, advanced tuning, and robust build make it an excellent choice for multi-axis OEM machines.
