Adjustable speed electrical power drive systems - Part 5-3: Safety requirements - Functional, electrical and environmental requirements for encoders

IEC 61800-5-3:2021, which is a product standard, specifies requirements and makes recommendations for the design and development, integration and validation of safety-related encoder (Encoder(SR)) in terms of their functional safety considerations, electrical safety and environmental conditions. It applies to Encoder(SR), being sensors as part of a PDS(SR). This document can also be referred to and used for Encoder(SR) in any other safety-related application, for example safety-related position monitoring. This document is applicable where functional safety of an encoder is claimed and the Encoder(SR) is operating mainly in the high demand or continuous mode. The requirements of IEC 61800-5-2:2016 for PDS(SR) apply to Encoder(SR) as applicable. This document includes additional or different requirements for Encoder(SR). It sets out safety-related considerations of Encoder(SR) in terms of the framework of IEC 61508 (all parts), and introduces requirements for Encoder(SR) as subsystems of a safety-related system. It is intended to facilitate the realisation of the electrical/electronic/programmable electronic (E/E/PE) and mechanical parts of an Encoder(SR) in relation to the safety performance of safety sub-function(s) of an Encoder(SR).

Entraînements électriques de puissance à vitesse variable - Partie 5-3: Exigences de sécurité - Exigences fonctionnelle, électrique et environnementale pour codeurs

L'IEC 61800-5-3:2021, qui est une norme de produit, spécifie des exigences et donne des recommandations pour la conception et le développement, l'intégration et la validation des codeurs relatifs à la sécurité (codeurs(SR)), au regard de leur sécurité fonctionnelle, de leur sécurité électrique et des conditions d'environnement. Elle s'applique aux codeurs(SR) qui sont des capteurs qui font partie d'un PDS(SR). Le présent document peut également servir de référence et être utilisé pour les codeurs(SR) dans le cadre de toute autre application relative à la sécurité, par exemple la surveillance de position relative à la sécurité. Le présent document est applicable lorsque la sécurité fonctionnelle d'un codeur est revendiquée et que le codeur(SR) fonctionne principalement en mode à sollicitation élevée ou en mode continu. Les exigences de l'IEC 61800-5-2:2016 concernant les PDS(SR) s'appliquent aux codeurs(SR), selon le cas. Le présent document comprend des exigences supplémentaires ou différentes pour les codeurs(SR). Il expose des considérations relatives à la sécurité des codeurs(SR), prises dans le cadre de l'IEC 61508 (toutes les parties), et présente des exigences pour les codeurs(SR) en tant que sous-systèmes d'un système relatif à la sécurité. Il est destiné à faciliter la réalisation des parties électriques/électroniques/électroniques programmables (E/E/PE) d'un codeur(SR) en liaison avec la performance de sécurité d'une ou de plusieurs sous-fonctions de sécurité d'un codeurs(SR)
