Sigma 5 vs. Sigma 7: Choosing Your Yaskawa Servo Champion

Choosing between Yaskawa’s flagship Sigma 5 and Sigma 7 series is about matching your application’s ambition to the right performance tier. Both are excellent, but key differences guide the choice.

For Ultimate Performance & Cutting-Edge Tech: Choose Sigma 7.
If your application demands the absolute best, Sigma 7 is the answer. It’s designed for the most challenging tasks:

• Unmatched Precision & Speed: Features like advanced vibration suppression II+ and high-frequency responsiveness make it ideal for ultra-high-speed packaging, precision laser cutting, or sophisticated robotics where settling time and accuracy are critical.
• Future-Ready Connectivity: It natively supports the latest industrial networks, including EtherCAT, for seamless integration into smart, Industry 4.0-ready factories.
• Handling Extreme Loads: Its robust control is superior for applications with significant load fluctuations or high inertia.

For Proven Reliability & Cost-Effective Excellence: Choose Sigma 5.
For the vast majority of industrial applications, the Sigma 5 series remains a powerhouse. It’s the proven, versatile choice when:

• You Need Robust, All-Around Performance: It delivers exceptional speed, torque stability, and reliability for CNC machines, material handling, and general automation.
• Value is a Key Driver: Sigma 5 offers outstanding performance at a more accessible price point, providing a fantastic return on investment.
• Simplifying Upgrades: If you’re modernizing an existing Sigma-II system, upgrading to Sigma 5 is often very straightforward.

The Bottom Line:
Think of Sigma 7 for peak, next-generation performance in the most demanding roles. Think of Sigma 5 for superior, cost-effective performance in a wide range of general to high-performance applications. Define your speed, precision, and connectivity needs first, and the right choice becomes clear.
