Yaskawa SGDH-15DE-OY Sigma-II 1.5kW 400V Three-Phase Servo Drive

Product Overview

The Yaskawa SGDH-15DE-OY is a Sigma-II series 400 V class AC SERVOPACK designed for single-axis control of compatible servo motors with a rated capacity of up to 1.5 kW. It supports precision position, speed, and torque control in industrial motion systems.

The -OY suffix identifies a system-specific Yaskawa/Omron configuration. The complete suffix, hardware revision, controller project, and installed machine configuration must be checked before using it to replace a standard SGDH-15DE or another SGDH variant.

Main Features

• 1.5 kW applicable servo motor capacity
• Three-phase 380–480 VAC main power input
• Position, speed, and torque control modes
• Analog voltage and pulse train command support
• Sigma-II serial encoder interface
• Automatic tuning and vibration suppression
• OY system-specific configuration

Technical Specifications

Compatible System and Applications

The SGDH-15DE-OY is intended for selected Yaskawa Sigma-II 400 V servo motor configurations, including compatible SGMGH and SGMSH motors. Typical applications include machine tools, printing machinery, packaging equipment, automated production lines, indexing systems, and material handling machinery.

Because this is an -OY variant, confirm the host controller, controller project, command interface, communication network, installed application or interface module, motor voltage, encoder type, brake option, regenerative resistor, and cable set.

Maintenance and Replacement Notes

Back up all original parameters before removing the existing SERVOPACK. Confirm the full SGDH-15DE-OY model, nameplate revision, firmware or hardware version, connector assignments, and original machine documentation. Do not assume that SGDH-15DE and SGDH-15DE-OY are directly interchangeable.

After installation, verify the incoming voltage and phase, protective grounding, motor and encoder wiring, brake control, regenerative circuit, limit signals, alarm outputs, electronic gearing, rotation direction, and tuning parameters. Initial commissioning should be performed at reduced speed.

Related Models

Related models include SGDH-10DE-OY, SGDH-20DE-OY, SGDH-15DE, and SGDH-30DE-OY. Differences in power rating, full suffix, connectors, firmware, system interface, and motor matching must be checked before replacement.

Inquiry and Supply Notes

Please provide clear photographs of the complete nameplate and connectors together with the controller model, controller project, communication network, motor model, encoder type, brake requirement, cable part numbers, installed modules, hardware or firmware revision, and parameter backup. Product condition and supplied accessories should be confirmed separately.
