FT91 Servo Amplifier with Functional Safety over EtherCAT Introduction

This document introduces Yaskawa's FT91 servo amplifier, which integrates Functional Safety over EtherCAT (FSoE) to replace traditional hard-wired safety systems, reducing wiring, cabinet footprint, and commissioning time. It details model number designations, safety ratings up to SIL3/PLe, and configuration examples using the Advanced Safety Module for networked machine safety.
