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 200eco.
This means that a complete digital system is available that is suitable for complex
machining tasks.
