Yaskawa SGD7S-2R8A20A Sigma-7 SERVOPACK 200V 400W MECHATROLINK-III

Product Overview

The Yaskawa SGD7S-2R8A20A is a Sigma-7 series single-axis SERVOPACK designed for 200 V class, 400 W rotary servo systems. Its MECHATROLINK-III interface supports deterministic motion communication between the servo amplifier and a compatible machine controller, making the unit suitable for synchronized multi-axis equipment requiring stable positioning, fast command response and repeatable production performance.

Main Features

• Rated for a compatible 400 W Yaskawa Sigma-7 servo motor.
• MECHATROLINK-III interface for coordinated motion-control networks.
• High 3.1 kHz speed frequency response for rapid machine-cycle operation.
• Supports high-resolution 24-bit serial encoder feedback.
• Advanced tuning functions help reduce setup time and mechanical vibration.
• Integrated STO safety function supports machine safety system design.

Technical Specifications

Compatible System and Applications

This SERVOPACK is commonly applied to electronic assembly equipment, packaging machinery, synchronized conveyors, indexing tables, semiconductor equipment and compact robotic axes. It should be connected to a compatible Yaskawa 400 W servo motor and a controller supporting MECHATROLINK-III communication.

Maintenance and Replacement Notes

Before replacement, confirm the complete SGD7S-2R8A20A nameplate code, motor model, encoder type, controller network, station settings, firmware requirements and connector arrangement. Parameter backups should be obtained from the existing drive whenever possible. Also inspect the motor cable, encoder cable, network cable, grounding and braking circuit before commissioning.

Related Models

Related configurations include SGD7S-2R8A00A for analog/pulse control, SGD7S-2R8AA0A for EtherCAT communication and SGD7S-2R8A30A for alternative network configurations. These models are not automatically interchangeable because their command interfaces and controller requirements differ.

Inquiry and Supply Notes

Please provide the complete model code, motor model, controller model, required quantity and equipment application when requesting a quotation. Photographs of the original nameplate and connectors are recommended for replacement projects.
