Description
The Yaskawa SGDM-15DN is an AC servo amplifier of the Sigma-II series for 400 V servo applications in the power range up to 1.5 kW. The SGDM series is technically based on the SGDH platform, meaning that alarms and troubleshooting are fully compatible with the SGDH series. The device is designed for precise axis control, high dynamics, and reliable continuous operation in industrial automation environments.
