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.

Function

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

Safety functions

Integrated safety functions

Failsafe controls are characterized by their integrated safety functions, which they provide to the user as possible responses to safety-related events. The SINUMERIK Safety Integrated Functions available in Siemens controls are described below. 

Safe Torque Off (STO)

STO safety sets the drive into a torque-free condition: an undesirable restart is safely prevented. A fast restart is possible after STO has been deselected as the DC link remains charged.

Safe Stop 1 (SS1)

The drive is quickly and safely stopped and monitored – especially for high moments of inertia.

Safe Stop 2 (SS2)

The drive is quickly and safely stopped and then SOS is activated.

Safe Operating Stop (SOS)

The position is safely held and monitored at standstill for each drive control.

Safe Brake Control (SBC)

A holding brake is controlled and monitored in a safety-related fashion, especially for vertical axes; is always activated in parallel with STO.

Safe Brake Test (SBT)

Up to two brakes per axis can be cyclically tested using the SBT diagnostic function.

Safely-Limited Speed (SLS)


The speed/velocity value of the drive is monitored in safety-related fashion, and a configurable stop response is initiated when the limit value is violated.

Safe Speed Monitor (SSM)


A safety-related velocity/speed monitoring function supplies a safety-rated signal as long as the drive operates below a specified speed/feed velocity.

Safe Direction (SDI)

The direction of rotation is monitored in a safety-related fashion so that the drive can only move in the permissible direction; a configurable fault response is initiated if the drive moves in the incorrect direction.

Safetly-Limited Acceleration (SLA)

It is safely monitored that the drive does not exceed a preset acceleration limit value.

Safe-Limited Position (SLP)

Protection zones are monitored in a safety-related fashion using defined traversing ranges.

Safe Position (SP)

The SP function transfers the safe position actual values of the drive to the F control for further processing via PROFIsafe.

Safe cam (SCA)

Safe cams supply a safety-related signal if the drive is located within a configured position range.
