Siemens SINAMICS G220 - Machinery Directive

Benchmarks for establishing whether or not a su󹪟cient level of functional safety has
been achieved include the probability of hazardous failures, the fault tolerance and the
quality that is to be guaranteed by avoiding systematic faults. This is expressed in the
standards using speci󹪝c classi󹪝cation. In IEC61800‑5‑2, IEC62061 "Safety Integrity Level"
(SIL) andISO13849‑1 "Category" and "Performance Level" (PL).
14.12.13 Machinery directive
Overview
The basic safety and health requirements speci󹪝ed in Annex I of the Directive must be ful󹪝lled
for the safety of machines.
Description
The protective goals must be implemented responsibly to ensure compliance with the Directive.
Manufacturers of a machine must verify that their machine complies with the basic
requirements. This veri󹪝cation is facilitated by means of harmonized standards.
IEC61800‑5‑2 Adjustable-speed electrical power drive systems Part 5-2 is relevant for the
Machinery Directive: Safety requirements - Functional safety.
Within the context of EN 61508, IEC61800‑5‑2 considers adjustable-speed electrical power
drive systems (PDS), which are suitable for use in safety-related applications (PDS(SR)).
IEC61800‑5‑2 places requirements on PDS(SR) as subsystems of a safety-related system. This
therefore permits the implementation of the electrical/electronic/programmable electronic
elements of a PDS(SR) taking into account the safety-relevant performance of the safety
function(s) of a PDS.
Manufacturers and suppliers of PDS(SR) can prove to users (e.g. integrators of control
systems, developers of machines and plants etc.) the safety-relevant performance of their
equipment by implementing the speci󹪝cations stipulated in standard IEC61800‑5‑2.
