Safe Stop 2 Safety Chain Solution for Servo Drives

This document describes a safety chain solution implementing the Safe Stop 2 (SS2) function for servo-driven machinery, achieving Performance Level e and SIL 3. It details the use of an enhanced safety module (eSM) to monitor deceleration ramps and standstill positions, with Safe Torque Off (STO) as a backup, and outlines the redundant channel architecture for category 3 compliance.
