SGDH15AESOY (SGDH-15AE-S-OY) Yaskawa Sigma-II 1.5kW SERVOPACK AC Servo Drive
SGDH15AESOY, full ordering code SGDH-15AE-S-OY, belongs to Yaskawa Sigma-II series SERVOPACK single-axis AC servo amplifier with rated power of 1.5kW, 200V class single/three-phase AC input. This servo drive is specially matched with Yaskawa SGMPH and SGMAH Sigma-II servo motors, widely used for high-precision positioning, speed and torque control on machine tools, printing machinery, packaging lines and automated assembly stations.
This servo amplifier supports three core control modes: position, speed and torque. It accepts pulse train command or analog voltage reference input, featuring high-speed DSP operation for fast response and low vibration motion performance. The front panel is equipped with 5-digit 7-segment display and LED status indicators, used to read real-time operating data and check fault alarm codes directly on site. It carries CN1 control signal connector, CN2 encoder feedback port and CN3 serial communication interface, supporting parameter upload, download and monitoring via SigmaWin configuration software. Built-in regenerative circuit allows connection of external regenerative resistors for high inertia and fast deceleration applications.
It integrates complete protection functions including overcurrent, overvoltage, undervoltage, overheat, overload, overspeed and encoder fault protection. Once abnormal signals are detected, the drive immediately cuts off torque output and triggers alarm codes to protect the amplifier and paired servo motor. The unit adopts cabinet base mounting design with IP20 protection rating, operating temperature range 0℃~55℃. It has excellent anti-electromagnetic interference capability, stable under workshop vibration, dust and oil mist environments. It supports incremental encoder feedback and electronic gearing function to flexibly adapt to different mechanical reduction ratios.
SGDH-15AE-S-OY is discontinued legacy industrial spare part. A large number of old CNC machines and automation production equipment still run on Sigma-II servo systems. When the original servo amplifier fails, replacing it with identical SGDH15AESOY can reuse the existing servo motor, encoder cables, power wiring and saved servo parameters. There is no need to modify PLC motion program or mechanical structure, which greatly reduces maintenance expense and shortens equipment downtime. Technicians can restore backup parameters without complicated loop re-tuning to resume production quickly.
We supply fully tested SGDH15AESOY servo drives. Before shipment, each unit undergoes comprehensive functional inspection, including power-on startup test, pulse/analog command response test, encoder feedback verification, JOG motor running test and protection function simulation. We verify alarm 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 automation system integrators, SGDH15AESOY is a reliable spare servo amplifier for legacy Yaskawa Sigma-II motion systems. It retains original positioning precision and dynamic performance of the machine, extends service life of automation assets and avoids high-cost full motion control system renovation.
