Product Overview

The Yaskawa SGD7S-120A20A is a Sigma-7 single-axis SERVOPACK rated for 1.5 kW servo motors in 200 V class automation systems. Its MECHATROLINK-III communication interface supports deterministic command transmission, coordinated multi-axis motion and centralized diagnostics through a compatible Yaskawa machine controller. The model is intended for applications requiring higher torque together with accurate synchronized positioning.

Main Features

• 1.5 kW motor capacity with 12.0 A rated output current.
• MECHATROLINK-III communication for coordinated motion control.
• High 3.1 kHz speed frequency response.
• Supports high-resolution 24-bit serial encoder feedback.
• Advanced autotuning compensates for load inertia and mechanical variation.
• Vibration suppression and resonance filtering improve positioning stability.

Technical Specifications

Compatible System and Applications

This SERVOPACK is suitable for packaging lines, printing machines, winding systems, synchronized conveyors, automated cutting equipment and medium-inertia positioning axes. It requires a compatible Yaskawa 1.5 kW servo motor and a controller supporting MECHATROLINK-III communication.

Maintenance and Replacement Notes

Confirm the complete SGD7S-120A20A code, connected motor, encoder type, brake option and controller network before replacement. Verify the controller project, station address, communication profile, firmware and parameter file. Inspect the network, motor and encoder cables together with the regenerative circuit, STO wiring and protective grounding.
