Series of articles: Product lifecycle management – but how!? (4)

Monday, 11. March 2019

With our product life cycle management publications, we would like to inform you about standards and regulations. Especially, we focus on SMEs to help them with functional safety issues.

Part 4 shows how EN 61800-5-2 serves as the basis for product/sector-specific standards.

To manage functional safety, which, amongst other things, requires topics such as responsibilities, employee qualification, and quality assurance measures, this product standard refers directly to IEC 61508-1.

On the technical side, we will now examine the requirements for the hardware electronics and the device software. The most basic drive safety function safe torque off (STO) can, in principle, be implemented as purely hardware-based. EN 61800-5-2 provides good support for this. On the other hand, it becomes interesting when more complex drive safety functions are required.
