标准摘要
[中文适用范围]： 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 power drive systems (PDS(SR)) in terms of their functional safety considerations. It applies to adjustable speed electrical power drive systems covered by the other parts of the IEC 61800 series of standards as referred in IEC 61800-2. This International Standard is applicable where functional safety of a PDS(SR) is claimed and the PDS(SR) is operating mainly in the high demand or continuous mode. While low demand mode operation is possible for a PDS(SR), this standard 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 series. This part of IEC 61800 sets out safety-related considerations of PDS(SR)s in terms of the framework of IEC 61508, and introduces requirements for PDS(SR)s as subsystems of a safety-related system. It is intended to facilitate the realisation of the electrical/ electronic/ programmable electronic (E/E/PE) parts of a PDS(SR) in relation to the safety performance of safety sub-function(s) of a PDS. Manufacturers and suppliers of PDS(SR)s by using the normative requirements of this part of IEC 61800 will indicate to users (system integrator, original equipment manufacturer) the safety performance for their equipment. This will facilitate the incorporation of a PDS(SR) into a safety-related control system using the principles of IEC 61508, and possibly its specific sector implementations (for example IEC 61511, IEC 61513, IEC 62061 or ISO 13849). By applying the requirements from this part of the IEC 61800 series, the corresponding requirements of IEC 61508 that are necessary for a PDS(SR) are fulfilled. This part of IEC 61800 does not specify requirements for: the hazard and risk analysis of a particular application; the identification of safety sub-functions for that application; the initial allocation of S/Ls 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 electrical, thermal and energy safety considerations, which are covered in IEC 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 sub-functions with a SIL not greater than SIL 3. [外文原描述]： IEC 61800-5-2:2016 RLV contains both the official IEC International Standard and its Redline version. The Redline version is available in English only and provides you with a quick and easy way to compare all the changes between the official IEC Standard and its previous edition. IEC 61800-5-2:2016 specifies requirements and makes recommendations for the design and development, integration and validation of safety related power drive systems (PDS(SR)) in terms of their functional safety considerations. It applies to adjustable speed electrical power drive systems covered by the other parts of the IEC 61800 series of standards as referred in IEC 61800-2. IEC 61800-5-2, which is a product standard, sets out safety-related considerations of PDS(SR)s in terms of the framework of IEC 61508, and introduces requirements for PDS(SR)s as subsystems of a safety-related system. It is intended to facilitate the realisation of the electrical/electronic/programmable electronic (E/E/PE) parts of a PDS(SR) in relation to the safety performance of safety sub-function(s) of a PDS. This edition includes the following significant technical changes with respect to the previous edition: a) rational added in the scope why low demand mode is not covered by this standard, b) definition added for: "category" and "safety function", c) "Other sub-functions" sorted into "Monitoring sub-functions" and "Output functions", d) deleted "proof test" throughout the document because for PDS(SR) a proof test is not applicable, e) replaced the term "safety function" by "safety sub-function" throughout the document, f) Updated references to IEC 61508 series Ed.2010, g) Added the principle rules of ISO 13849-1 and reference to tables of ISO 13849-2, h) 6.1.6 Text replaced by Table 2, i) 6.1.7 Integrated circuits with on-chip redundancy matched to changed requirement in IEC 61508-2: 2010, Annex E, j) 6.2.8 Design requirements for thermal immunity of a PDS(SR), k) 6.2.9 Design requirements for mechanical immunity of a PDS(SR), l) 6.1.6 SIL for multiple safety sub-functions within one PDS(SR), m) 6.1.7 Integrated circuits with on-chip redundancy, n) 6.2.1 Basic and well-tried safety principles, o) 6.2.2.1.4 Diagnostic test interval when the hardware fault tolerance is greater than zero, p) 6.2.5.2.7 PDS(SR) parameterization, q) 9 Test requirements, r) 9.3 Electromagnetic (EM) immunity testing, s) 9.4 Thermal immunity testing, t) 9.5 Mechanical immunity testing, u) Annex A Sequential task table, v) Annex D, D.3.16, Motion and position feedback sensors updated, w) Annex E Electromagnetic immunity (EM) requirement for PDS(SR), x) Annex F Estimation of PFDavg value for low demand with given PFH value.
