SINUMERIK Safety Integrated

Using the SINUMERIK Safety Integrated function, for SINUMERIK 840D sl, for all

power/performance classes, integrated safety functions are available in conjunction

with the SINAMICS S120 drive system; these are used to monitor standstill (zero

speed), velocity and position.

SINAMICS S120 is used in conjunction with 1FT6/1FK6/1FK7 three–phase servo-

motors and 1FN linear motors for feed drives as well as 1FE and 1PH motors for

main spindle drives.

The safety–related sensors and actuators are connected through distributed I/O

via PROFIBUS–DP with the PROFIsafe profile, e.g. ET 200S, ET 200pro, ET

200eco, DP/AS–i F–Link.

This means that a complete digital system is available that is suitable for complex

machining tasks.

A two–channel, diverse system structure is formed on the basis of an existing mul-

ti–processor structure.
