3.2 Safety technology integrated in the system
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 servomotors 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.
