Adjustable speed electrical power drive systems - Part 5-3: Safety requirements - Functional, electrical and environmental requirements for encoders (IEC 61800-5-3:2021)

This part of IEC 61800, 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).
NOTE 1 The term "integration" refers to the Encoder(SR) itself, not to its incorporation into the safety-related
application.
This document can also be referred to and used for Encoder(SR) in any other safety-related
application, for example safety-related position monitoring.
NOTE 2 This document specifies only complementary functional safety, electrical safety and environmental condition
requirements that are not clearly provided by other parts of the IEC 61800 series.
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.
NOTE 3 While low demand mode operation is possible for an Encoder(SR), this document concentrates on high
demand and continuous mode. Safety sub-functions implemented for high demand or continuous mode can also be
used in low demand mode. Requirements for low demand mode are given in IEC 61508 (all parts) [2]. Some guidance
for the estimation of average probability of dangerous failure on demand (PFDavg) value is provided in
IEC 61800-5-2:2016, Annex F.
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 safetyrelated
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).
Manufacturers and suppliers of Encoder(SR) will, by using the normative requirements of this
document, indicate to users (system integrator, original equipment manufacturer) the safety
performance of the Encoder(SR). This will facilitate the incorporation of Encoder(SR) into
safety-related control systems using the principles of IEC 61508 (all parts), and possibly its
specific sector implementations (for example IEC 61511 (all parts) [3], IEC 61513 [4],
IEC 62061 [5] or ISO 13849-1 and ISO 13849-2 (see Clause 2).
By applying the requirements from this document, the corresponding requirements of
IEC 61508 (all parts) that are necessary for an Encoder(SR) are fulfilled.
This document does not specify requirements for:
• the functional properties of an Encoder(SR) without any safety relevance;
• the hazard and risk analysis of a particular application;
• the identification of safety sub-functions for that application;
• the initial allocation of SILs to those safety sub-functions;
• the driven equipment except for interface arrangements;
• secondary hazards (for example from failure in a production or manufacturing process);
• the Encoder(SR) manufacturing process;
• the validity of signals and commands to the Encoder(SR); and
• security aspects (e.g. cyber security or Encoder(SR) security of access).
NOTE 4 The functional safety requirements of an Encoder(SR) are dependent on the application, and can be
considered as a part of the overall risk assessment of the installation. Where the supplier of the Encoder(SR) is not
responsible for the driven equipment, the installation designer is responsible for the risk assessment, and for
specifying the functional and safety integrity requirements of the Encoder(SR).
This document applies to Encoder(SR) implementing safety sub-functions with a SIL not greater
than SIL 3.
This document provides additional information for Encoder(SR) claiming

Entraînements électriques de puissance à vitesse variable - Partie 5-3: Exigences de sécurité - Exigences fonctionnelle, électrique et environnementale pour codeurs (IEC 61800-5-3:2021)

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)

Električni pogonski sistemi z nastavljivo hitrostjo - 5-3. del: Varnostne zahteve - Funkcionalne, električne in okoljske zahteve za kodirnike (IEC 61800-5-3:2021)

Ta del standarda IEC 61800, ki je standard za izdelek, določa zahteve in podaja priporočila za načrtovanje in izdelavo, vgradnjo in potrjevanje z varnostjo povezanega kodirnika (Encoder(SR)) v smislu funkcionalne varnosti, električne varnosti in okoljskih pogojev. Uporablja se za kodirnik Encoder(SR) kot senzor v električnem pogonskem sistemu z nastavljivo hitrostjo (PDS(SR)).
OPOMBA 1: izraz »vgradnja« se nanaša na sam kodirnik Encoder(SR) in ne na njegovo vključitev v z varnostjo povezano aplikacijo.
Ta dokument se lahko nanaša in uporablja tudi za kodirnik Encoder(SR) v kateri koli drugi z varnostjo povezani aplikaciji, na primer v z varnostjo povezani kopirni napravi.
OPOMBA 2: Ta dokument določa samo zahteve za dopolnilno funkcionalno varnost, električno varnost in okoljske pogoje, ki niso jasno podani v drugih delih skupine standardov IEC 61800.
Ta dokument se uporablja, kjer se zahteva funkcionalna varnost kodirnika in kodirnik Encoder(SR) deluje predvsem v načinu z visokimi zahtevami ali neprekinjenem načinu.
OPOMBA 3: Čeprav je za kodirnik Encoder(SR) mogoče tudi delovanje v načinu z nizkimi zahtevami, se ta dokument osredotoča na delovanje v načinu z visokimi zahtevami in neprekinjenem načinu. Varnostne podfunkcije, ki so vpeljane za način z visokimi zahtevami ali neprekinjeni način, je mogoče uporabiti tudi v načinu z nizkimi zahtevami. Zahteve za način z nizkimi zahtevami so podane v standardu IEC 61508 (vsi deli) [2]. Nekaj navodil za ocenjevanje povprečne vrednosti verjetnosti nevarnih okvar na zahtevo (PFDavg) je podanih v dodatku F standarda IEC 61800-5-2:2016.
Zahteve standarda IEC 61800-5-2:2016 za električni pogonski sistem z nastavljivo hitrostjo se uporabljajo za kodirnik Encoder(SR), kjer je to ustrezno. Ta dokument vključuje dodatne ali različne zahteve za kodirnik Encoder(SR). Določa varnostne vidike za kodirnik Encoder(SR) v smislu okvira standarda IEC 61508 (vsi deli) in uvaja zahteve za kodirnik Encoder(SR) kot podsisteme varnostnega sistema. Namenjen je za lažjo realizacijo električnih/elektronskih/programirljivih elektronskih (E/E/PE) in mehanskih delov kodirnika Encoder(SR) v povezavi z varnostno zmogljivostjo varnostnih podfunkcij kodirnika Encoder(SR).
Proizvajalci in dobavitelji kodirnika Encoder(SR) bodo z uporabo normativnih zahtev tega dokumenta uporabnikom (integrator sistema, proizvajalec originalne opreme) navedli varnostno zmogljivost kodirnika Encoder(SR). To bo poenostavilo vključitev kodirnika Encoder(SR) v z varnostjo povezane nadzorne sisteme z uporabo načel iz standarda IEC 61508 (vsi deli) in po možnosti njegovih uvajanj za ustrezen sektor (npr. standard IEC 61511 (vsi deli) [3], IEC 61513 [4],
IEC 62061 [5] ali ISO 13849-1 in ISO 13849-2 (glej točko 2).
Z uporabo zahtev iz tega dokumenta se izpolnijo ustrezne zahteve standarda IEC 61508 (vsi deli), ki so potrebne za kodirnik Encoder(SR).
Ta dokument ne določa zahtev za:
• funkcionalne lastnosti kodirnika Encoder(SR) brez varnostnega vidika;
• analizo nevarnosti in tveganja za določeno uporabo;
• prepoznavanje varnostnih podfunkcij za to uporabo;
• začetno dodelitev stopenj varnostne celovitosti (SIL) tem varnostnim podfunkcijam;
• pogonsko opremo, razen za priprave vmesnika;
• sekundarne nevarnosti (npr. zaradi okvare pri postopku proizvodnje);
• postopek proizvodnje kodirnika Encoder(SR);
• veljavnost signalov in ukazov za kodirnik Encoder(SR); in
• varnostne vidike (npr. kibernetska varnost ali varnost dostopa do kodirnika Encoder(SR)).
OPOMBA 4: Zahteve za funkcionalno varnost kodirnika Encoder(SR) so odvisne od uporabe in jih je mogoče upoštevati kot del splošne ocene tveganja za namestitev. Če dobavitelj kodirnika Encoder(SR) ni odgovoren za pogonsko opremo, je načrtovalec namestitve odgovoren za oceno tveganja ter določanje zahtev glede funkcionalnosti in varnostne celovitosti kodirnika Encoder(SR).
Ta dokument se uporablja za kodirnik Encoder(SR), ki uvaja varnostne podfunkcije s stopnjo varnostne celo
