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.
