Product Overview

The Yaskawa SGD7S-550A00A is a high-capacity Sigma-7 SERVOPACK designed for 7.5 kW servo motors in 200 V class industrial systems. It uses analog voltage and pulse-train command references and provides 55.0 A rated output for large mechanical axes. This model is intended for machinery requiring high torque, rapid acceleration and accurate control of substantial loads.

Main Features

• 7.5 kW servo motor capacity with 55.0 A rated output current.
• Analog voltage and pulse-train command interface.
• 3.1 kHz speed frequency response.
• Supports high-resolution 24-bit serial encoder feedback.
• Advanced tuning functions assist high-inertia load control.
• Resonance filtering and vibration suppression improve stability.

Technical Specifications

Compatible System and Applications

This high-power SERVOPACK is suitable for large machine-tool axes, printing presses, forming machines, heavy material-handling equipment, winding systems and industrial positioning mechanisms. System engineering must consider motor torque, load inertia, power-circuit capacity, regenerative energy and braking requirements.

Maintenance and Replacement Notes

Confirm the complete SGD7S-550A00A nameplate, motor model, encoder type, input phase, power-cable size and protective-device ratings. Check the regenerative resistor or regenerative unit, braking circuit, cooling conditions, pulse format and controller parameters. Maintenance must be performed only after the main circuit is isolated and the DC bus is fully discharged.

Related Models

Related ratings include SGD7S-330A00A for 5 kW, SGD7S-470A00A for 6 kW and SGD7S-590A00A for 11 kW systems. Motor capacity and power-circuit requirements prevent direct substitution without an engineering review.
