SGDH15AESOY (SGDH-15AE-S-OY) Yaskawa Sigma-II 1.5kW AC Servo Drive
SGDH15AESOY, full model SGDH-15AE-S-OY, belongs to Yaskawa Sigma-II series SERVOPACK AC servo amplifier, rated 1.5kW, 200V class single/three-phase power input. This servo drive supports analog voltage command and pulse train position command input, widely matched with Yaskawa SGMPH and SGMBH series Sigma-II servo motors for high-precision positioning and speed control on machine tools, packaging machinery and automated assembly equipment.
This servo amplifier provides three standard control modes: position, speed and torque. It adopts high-speed digital signal processing algorithm to realize fast response and low vibration motion control. The front panel is equipped with digital display and LED status indicators for real-time running data reading and fault alarm code checking. It comes with CN1 control signal connector, CN2 encoder feedback port and CN3 serial communication port, supporting parameter setting and monitoring via Yaskawa SigmaWin software. Built-in regenerative circuit, external regenerative resistor can be connected for high deceleration load applications.
Integrated comprehensive protection functions include overcurrent, overvoltage, undervoltage, overheat, overload, encoder abnormality and over-speed protection. Once fault is detected, the drive cuts off torque output immediately and triggers alarm code to protect the amplifier and matched servo motor. The drive is designed for cabinet rack mounting with IP20 protection grade, working temperature range from 0℃ to 55℃. It features strong anti-electromagnetic interference performance to adapt to vibration, dust and oil mist in machining workshops. It accepts incremental encoder feedback signal and supports electronic gear function to flexibly match mechanical reduction ratio.
SGDH-15AE-S-OY is discontinued legacy Yaskawa automation spare part. Many old CNC machines and automation production lines still adopt Sigma-II servo systems. When the original servo drive fails, replacing it with identical SGDH15AESOY can reuse existing servo motor, encoder cable, power wiring and original servo parameter settings. There is no need to modify PLC motion program or mechanical structure, which greatly reduces maintenance cost and shortens equipment downtime. Technicians can directly restore backup parameters without complex loop re-tuning, and equipment can resume production quickly.
We supply fully tested SGDH15AESOY servo drives. Before shipment, each unit undergoes complete functional inspection including power-on startup test, pulse/analog command response test, encoder feedback verification, JOG motor running test and protection function simulation. We check alarm code output stability and communication connectivity with SigmaWin software. All products come with 12-month warranty. Our automation technical team provides remote support for wiring guidance, parameter backup, servo gain adjustment and fault diagnosis. Fast global shipping is available for urgent maintenance orders.
For CNC maintenance engineers and system integrators, SGDH15AESOY is a reliable spare servo amplifier for legacy Yaskawa Sigma-II motion systems. It retains original positioning accuracy and dynamic performance of the machine, extends service life of automation assets and avoids high-cost full motion control system renovation.
