Integrated – and "ready-to-run"

SINUMERIK Safety Integrated

Implementing innovative safety concepts that offer maximum safety for people and machines is particularly easy with SINUMERIK Safety Integrated. In combination with SINAMICS drives, the SINUMERIK controls offer numerous benefits - together with customized safety functions: less engineering effort thanks to integrated safety functions that can be matched individually to any requirement; less external wiring due to simple connection with I/Os and converters using PROFINET and DRIVE CLiQ; faster commissioning through automated acceptance testing with the required protocols.

SINUMERIK with Safety Integrated

Efficient and cost-efficient

SINUMERIK Safety Integrated is a wide-ranging safety package that helps to protect people as well as machines. Thanks to the comprehensive integration of the safety functions in the control and drive technology, the system is extremely efficient and economical; for example, in setup and test operation while the protective door is open. The safety functions meet the requirements of DIN EN 61508 for use up to and including SIL 2 (Safety Integrity Level), and Category 3, and PL d (Performance Level) according to DIN EN ISO 13849. This allows the main requirements for functional safety to be implemented simply and economically.


The safety functions are available in all modes and can communicate with the process using safety-related input/output signals. They can be implemented for each individual axis and spindle. The following Safety Integrated functions are available:

Safety Integrated basic function
System-integrated safety functions
Safe pulse cancellation of the drive
Safe monitoring of the speed
Safe control of a holding brake
Safe monitoring of standstill and position
Safe shutdown of a drive
Safe processing of the sensors and actuators
