适用范围：This part of IEC 61800 specifies requirements and makes recommendations for the designand development, integration and validation of PDS(SR)s in terms of their functional safetyconsiderations. It applies to adjustable speed electric drive systems covered by the otherparts of the IEC 61800 series of standards.This International Standard is only applicable where functional safety of a PDS(SR) is claimedand the PDS(SR) is operating in the high demand or continuous mode (see 3.10). For lowdemand applications, see IEC 61508.This part of IEC 61800, which is a product standard, sets out safety-related considerations ofPDS(SR)s in terms of the framework of IEC 61508, and introduces requirements forPDS(SR)s as subsystems of a safety-related system. It is intended to facilitate the realisationof the electrical/electronic/ programmable electronic (E/E/PE) elements of a PDS(SR) inrelation to the safety performance of safety function(s) of a PDS.Manufacturers and suppliers of PDS(SR)s by using the normative requirements of this part ofIEC 61800 will indicate to users (control system integrators, machinery and plant designers,etc.) the safety performance for their equipment. This will facilitate the incorporation of aPDS(SR) into a safety-related control system using the principles of IEC 61508, and possiblyits specific sector implementations (for example IEC 61511, IEC 61513, IEC 62061) orISO 13849.Conformity with this part of IEC 61800 fulfils all the requirements of IEC 61508 that arenecessary for a PDS(SR).This part of IEC 61800 does not specify requirements for:• the hazard and risk analysis of a particular application;• the identification of safety functions for that application;• the initial allocation of SILs to those safety functions;• the driven equipment except for interface arrangements;• secondary hazards (for example from failure in a production or manufacturing process);• the electrical, thermal and energy safety considerations, which are covered inIEC 61800-5-1;• the PDS(SR) manufacturing process;• the validity of signals and commands to the PDS(SR).This part of IEC 61800 only applies to PDS(SR)s implementing safety functions with a SIL notgreater than SIL 3.
