Yaskawa SGDH-04AE-OY Sigma II 400W Servo Drive: Specifications, Applications and Replacement Guide

The Yaskawa SGDH-04AE-OY is a Sigma II series servo drive designed for industrial motion control applications. With a 400 W power rating and a single-phase 200 V class power supply, this servo amplifier is relevant to equipment maintenance teams, automation engineers, and industrial spare-parts buyers.

When a servo drive fails, identifying the exact model is essential for minimizing downtime and avoiding compatibility problems. The complete model number, SGDH-04AE-OY, should be checked against the existing unit and the machine's electrical documentation before purchasing a replacement.

The SGDH series belongs to Yaskawa's Sigma II servo system family. The SGDH-04AE model is specified for a 400 W servo motor application with a single-phase 200 V class supply.

This drive is used as part of a servo system, where the amplifier controls the connected servo motor according to the requirements of the machine and its motion controller.

Important: Confirm the complete model suffix, communication interface, motor compatibility, and electrical requirements using the original nameplate and Yaskawa documentation. Do not assume that every SGDH-04AE variant has the same options or interface configuration.

A servo drive receives commands from a motion controller and regulates the connected servo motor. Depending on the system configuration, the servo system can be used for speed control, torque control, or position control.

The Yaskawa Sigma II SGDH series was designed for industrial servo applications that require controlled motor movement and repeatable machine operation.

Typical system components include:

• Servo amplifier

• Compatible servo motor

• Motor power and feedback cables

• Motion controller or machine controller

• Appropriate power supply and protective devices

The exact motor and control interface must match the installed system. Always consult the original machine drawings and the relevant Yaskawa manual when checking compatibility.

The SGDH-04AE model is rated for a 400 W servo motor application. This makes the model relevant when identifying a replacement for an existing 400 W Sigma II servo system.

When selecting a drive, compare the motor's rated capacity and current requirements with the drive specifications. Power rating alone is not enough to confirm compatibility.

The SGDH-04AE is a single-phase 200 V class model. Verify the actual supply voltage, wiring arrangement, grounding, and protection requirements before installation.

Using the wrong voltage class or wiring configuration can damage equipment or create an electrical safety risk.

The SGDH-04AE-OY is identified with Yaskawa's Sigma II SGDH family. When servicing an existing Sigma II installation, use the complete model number to distinguish the required drive from other models in the series.

Similar-looking servo amplifiers may differ in power rating, supply voltage, interface options, or motor compatibility.

Servo drives are used in machines where motor speed, torque, or position must be controlled according to the application.

Depending on the complete system configuration, typical applications can include automated machinery, packaging equipment, material handling, and production equipment.

Servo systems can control coordinated movement in packaging, feeding, cutting, and processing machinery. Correct drive and motor matching helps maintain the intended motion profile.

Industrial machines may use servo drives to control moving axes, positioning mechanisms, and synchronized operations.

Certain conveyors and handling mechanisms use servo motion control where controlled movement or repeatable positioning is required.

For maintenance teams, locating the exact SGDH-04AE-OY model can be important when repairing an existing machine and preserving its established control architecture.

These are general servo-drive application categories. The suitability of this particular model depends on the original machine design and connected components.

When sourcing a replacement for the Yaskawa SGDH-04AE-OY, verify the following details before ordering.

1. Complete model number: Check that the label reads SGDH-04AE-OY, including the suffix.

2. Power rating: Confirm the 400 W application requirement.

3. Supply voltage: Verify the single-phase 200 V class supply and actual site wiring.

4. Servo motor: Confirm the connected motor model and electrical compatibility.

5. Feedback connections: Check encoder and feedback cable requirements.

6. Control interface: Verify the installed communication option and controller requirements.

7. Parameters: Record the existing drive parameters and configuration before replacement.

8. Mounting and wiring: Compare terminal layout, dimensions, connectors, and installation clearances.

9. Alarm history: Identify the cause of the original drive failure before commissioning the replacement.

10. Commissioning: Follow the relevant Yaskawa manual and the machine manufacturer's procedure.

A drive with a similar appearance or matching power rating is not necessarily a compatible replacement. Verify the complete configuration before installation.

Industrial buyers often search for servo drives using the model printed on the equipment label. For this product, use both the complete model and the base model when researching availability.

Relevant search phrases include:

• Yaskawa SGDH-04AE-OY

• SGDH-04AE-OY servo drive
