Lower costs, increased safety

While conventional safety technology always requires addi-

tional contactors, safety relays and interlocking circuits, for

the integrated safety technology from Siemens, all of these

additional electromechanical components are eliminated

from the very start.

And even more: as the safety-relevant signals can be trans-

ferred via standard fieldbuses, the complexity and therefore

wiring costs are reduced. As a consequence, the high re-

quirements of the safety standards can be far more simply

implemented. And not only this, as a result of the lower

number of components, machine availability is increased.

It is safe to say that SINAMICS Safety

Safety Integrated for SINAMICS

Almost all members of the SINAMICS family have safety

functions integrated in the drive – and in many instances,

an encoder is not required. These are certified according to

IEC 61508/SIL 2, EN ISO 13849-1 Cat. 3 and PL d.

There is an increased risk of injury to personnel and damage to the machine wherever there are rotating units –

such as saws, rolls and spindles. This is also the case for linear handling axes and machine slides, frequently

with high velocities. Safety Integrated is the safety concept that reliably masters specific dangerous situations.

It has a significantly faster response time and a higher degree of functionality with generally unchanged and

occasionally even increased productivity.
