ACS880-01 and AC500-S Safely-Limited Speed Function Implementation Guide

This technical document details the design and implementation of a safely-limited speed (SLS) safety function using an ACS880-01 industrial drive and an AC500-S safety PLC, along with other ABB safety devices. It covers the required safety standards (EN/IEC 62061, EN ISO 13849-1, EN/IEC 60204-1, EN/IEC 61800-5-2), SIL/PL calculations using ABB’s Functional safety design tool, and the operation of the SLS function including ramp monitoring, activation via an Eden OSSD sensor, and safe torque off (STO) actuation.
