Integrated safety functions in the Sinumerik drive from Siemens meet the requirements of safety Category 3, compliance with EN 954-1, and are an integral part of the basic system. Additional sensors are not necessary, which reduces machine installation effort and results in a "slimline" control cabinet. The scope of functions supported includes system monitoring at speed and standstill, as well as functions for safe travel range limiting and range detection.
A multi-processor architecture forms a dual-channel, system structure, and safety functions are redundantly integrated in NC, drive and internal PLC. Process variables and safety-relevant system data are cross monitored. Safety functions are available in all operating modes and communicate with the process using input/output signals.

What should be the perception of a product’s real-world performance with regard to the published spec sheet? While it is easy to assume that the product will operate according to spec, what variables should be considered, and is that a designer obligation or a customer responsibility? Or both?
Biomimicry has already found its way into the development of robots and new materials, with researchers studying animals and nature to come up with new innovations. Now thanks to researchers in Boston, biomimicry could even inform the future of electrical networks for next-generation displays.
