SINUMERIK Safety Integrated


SINUMERIK Safety Integrated is a comprehensive safety package that helps to protect both personnel as well as machines. This is extremely efficient and cost effective thanks to the safety functions that are completely integrated into the control and drive technology. Not only this, your machine can be safely and practically operated under all of the specified operating conditions. For instance, in the setting-up and test modes with the protective door open. The safety functions comply with the requirements laid down in DIN EN 61508 for use up to and including SIL 2 (Safety Integrity Level), Category 3 and PL d (Performance Level) according to DIN EN ISO 13849. As a consequence, the essential requirements relating to functional safety can be simply and cost-effectively implemented.
