The Sigma-7 line of rotary, linear and direct-drive servos and amplifiers offer almost double the bandwidth of Yaskawa’s Sigma-5 servos for quicker response to system commands. Features include 24-bit encoding that boosts precision; a 20% smaller footprint and amplifier design that saves control panel space; a package of algorithms that correct machine imperfections, including ripple compensation, anti-resonance and friction model compensation; dual-axis amplifiers that mount in smaller spaces, cut parts counts and regenerate power for long-term energy conservation; and full compatibility with Sigma-5 servos currently in the field, enabling replacement without the need for reprogramming or re-engineering existing equipment.
