SIMATIC - Failsafe library LDrvSafe to control the Safety Integrated functions of the SINAMICS drive family

  • Entry
  • Associated product(s)
The library includes fail-safe SIMATIC S7 blocks to implement various Safety applications in conjunction with a S7-1200F, S7-1500F, failsafe Open/Software Controller, SINUMERIK ONE and SINAMICS drives as well as SIMATIC Micro-Drive coupled through PROFIsafe.

This library is intended to realize different Safety application, e.g. simple control of SINAMICS Safety Functions via PROFIsafe as well as failsafe diameter detection, up to Safety Integrity Level 2 (EN 62061) and Performance Level d, Category 3 (EN ISO 13849-1).

Overview about realized function blocks:

  • PROFIsafe control words (telegrams 30 to 903 with SINAMICS G and S as well as SIMATIC Micro-Drive)
  • PROFIsafe status words (telegrams 30 to 903 with SINAMICS G and S as well as SIMATIC Micro-Drive)
  • Safety Info and Control Channel (telegrams 700 and 701 with SINAMICS G and S)

  • Safe Referencing to use Safety Functions SLP, SP and SCA

  • Acknowledge changed hardware to adapt hardware checksums, e.g. after changing safety-relevant hardware

  • Failsafe calculation of the velocity

  • Safe brake test in connection with technology objects

    • Safe diameter calculation and adaption of the SLS limit at winding application 
      • Calculation of average value 
      • Monitoring of discrepancy
      • Unmasking sensor values
      • Calculation of radius
      • Calculation of Safely-Limited Speed as a function of the radius
