Yaskawa Sigma-7 SGD7S-R90A00A 100W AC Servo Drive with 3.1kHz Bandwidth and 24-bit Encoder Support

The Yaskawa SGD7S-R90A00A (including the hardware-optimized SGD7S-R90A00A002) is a high-precision 100W AC Servo Amplifier. As part of the world-renowned Sigma-7 Series, this drive is engineered to provide the fastest response and highest accuracy in the compact 0.1kW power class.

Operating on a single-phase 200V-230V input, the SGD7S-R90A00A is the go-to solution for developers who require ultra-fast settling times and sub-micron positioning. Its "Tuningless" technology and advanced vibration suppression make it ideal for high-speed pick-and-place, laboratory automation, and delicate 3C electronic assembly.

Essential parameters for engineers and mechanical designers:

• Industry-Leading 3.1kHz Bandwidth: The Sigma-7 series boasts a speed response frequency of 3.1kHz. For 100W applications, this translates to nearly instantaneous command execution and significantly reduced cycle times, allowing for higher throughput in high-speed sorting and inspection lines.
• Yaskawa "Tuningless" Technology: The SGD7S-R90A00A automatically adjusts to varying load inertias (up to 30:1 ratio) without the need for manual gain tuning. This ensures stable, vibration-free operation even in mechanical systems that change over time, drastically reducing commissioning costs.
• Advanced 24-bit Resolution: When paired with Sigma-7 motors (like the SGM7J or SGM7A), this drive supports 24-bit encoders (16,777,216 pulses per revolution). This provides ultra-smooth rotation at low speeds and unmatched positioning accuracy for high-precision optics and medical lab equipment.
• Comprehensive Vibration Suppression: Equipped with advanced notch filters and ripple compensation, the SGD7S-R90A00A actively detects and cancels mechanical resonance. This protects delicate mechanical components and ensures ultra-fine surface finishes in micro-machining.

• Semiconductor Manufacturing: Wafer handling, wire bonding, and inspection.
• 3C Electronic Assembly: High-speed SMT placement and smartphone testing.
• Medical & Laboratory Automation: Precise liquid handling, centrifuges, and robotic surgery.
• Printing & Packaging: Accurate label placement and small-scale synchronized axes.
• Optical Equipment: Precision lens grinding and high-speed shutter control.
