Product Overview

The Yaskawa SGD7S-120A00A is a 1.5 kW Sigma-7 single-axis servo amplifier for medium-power industrial motion applications. With a 12.0 A rated output and Analog/Pulse command interface, it supports demanding positioning, speed and torque control tasks while retaining compatibility with conventional machine controller reference signals.

Main Features

• 1.5 kW maximum applicable motor capacity
• 12.0 A rated servo output current
• Analog voltage and pulse train command references
• 3.1 kHz response for fast dynamic control and short settling time
• 24-bit serial encoder feedback
• Advanced automatic tuning and vibration suppression
• Single-axis architecture for independent industrial motion
• STO safety support with additional functions dependent on configuration

Technical Specifications

Compatible System and Applications

This model is intended for compatible 1.5 kW Sigma-7 servo motors used in machine tools, forming equipment, industrial handling, packaging lines, converting machines and high-inertia positioning mechanisms. Motor selection must account for continuous torque, peak torque, rated speed, encoder configuration and regenerative operating conditions.

Maintenance and Replacement Notes

For replacement projects, verify the complete order code, design revision, motor model, feedback type and command interface. Inspect the main circuit supply, control supply, brake control circuit, regenerative resistor and grounding arrangement. Copying parameters from a different power rating or network version can cause commissioning faults or unstable operation.
