SINUMERIK Safety Integrated

SINUMERIK Safety Integrated is a comprehensive safety package that helps protect both man and machinery. It ensures high efficiency and profitability due to the complete integration of safety functions into the control and drive technology. In addition, you can safely and practicably operate your machine under all operating conditions requested, for example, in setup and test mode with open protective door. The safety functions fulfil all requirements according to DIN EN 61508 for applications up to and including SIL 2 (Safety Integrity Level) and Category 3 as well as PL d (Performance Level) according to DIN EN ISO 13849. You can thus conveniently and economically fulfil the major requirements placed on functional safety.

Included in the function scope are the following, e.g.:

• Functions to safely stop drives
• Functions to safely monitor motion
• Direct connection of all safety-related signals and internal logic operation.

• Functions for operator and machine protection
• Short response times due to integration into the drive system
• Suitable for all modes of operation
• Replaces external electromechanical devices

The safety functions are available in all modes and can communicate with the process via safety-related input/output signals.

They can be realized for each individual axis and spindle:

• Safe stopping process
  Safely transfers the drives from motion to standstill as soon as a monitoring function or a sensor (e.g. a light barrier) responds.
• Safe operation stop (SBH)
  This safety function monitors the drives for standstill. The drives are fully functional in the bearing.
• Safe standstill (SH)
  Pulse suppression of the drives and safe, electronic interruption of power supply
• Safely reduced speed (SG)
  Monitoring of configurable speed limits, e.g. upon setup without pressing an enable key.
• Safe software limit switches (SE)
  Variable traversing range limits
• Safe software cams (SN)
  Area recognition
• Safety-relevant input/output signals (SGE/SGA)
  Process interface
• Safe programmable logic (SPL)
  Direct connection of all safety-relevant signals and their internal logic combination.
• Safe brake management (SBM)
  Two-channel brake control and cyclic brake test
• Safety-relevant communication via standard bus
  Connection of distributed I/Os for process and safety signals via PROFIBUS with PROFIsafe
• Safe network transition between ASI and PROFIBUS
  The DP/AS-I F-Link provides for a safe transition from ASIsafe to PROFIsafe. All safety-related signals are collected via the AS-i bus.
• Integrated acceptance test
  Partially automated acceptance test for all safety-relevant functions. Convenient operation of the test sequence, automatic configuration of trace functions and automatic generation of the acceptance certificate

• High safety:
  Contiguous realization of Class 3 / SIL 2 safety functions (EN 954-1)
• High flexibility:
  Practice-oriented safety and operating concepts can be realized
• High cost effectiveness:
  Reduction of hardware and installation costs
• High availability:
  Electromechanically operated contact mechanisms susceptible to interference are no longer required

Fast and convenient evaluation of safety functions
Take the direct route to obtain a safe machine using the “Safety Evaluation Tool“ for the standards IEC 62061 and ISO 13849-1. When implementing safety functions on machines, our TÜV-tested tool guides you quickly and safely through the necessary calculation steps (TÜV = German Technical Inspection Authority).
