ACS880-01 Encoderless Safely-Limited Speed Implementation Guide

This document details the design and implementation of an encoderless safely-limited speed (SLS) safety function using an ACS880-01 drive and an FSO-12 safety functions module, compliant with EN/IEC 62061, EN ISO 13849-1, and other machinery standards. It covers the operation, safety performance calculations using ABB's Functional safety design tool, and verification steps to achieve SIL 3 / PL e.
