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, PROFINET 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

multi--processor structure.
