SINUMERIK Safety Integrated Siemens

Обзор



Drive Based Safety Integrated provides integrated safety functions that support the implementation of highly effective personnel and machine protection.

The safety functions comply with the requirements of Category 3 as well as Performance Level PL d according to DIN EN ISO 13849‑1 and safety integrity level SIL 2 according to DIN EN 61508. Consequently, important functional safety requirements can be implemented easily and economically.

The functional scope includes, for example:

  • Functions for safe monitoring of standstill
  • Functions for safe monitoring of speed

Функции



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

The following Safety Integrated functions are available (terms in accordance with IEC 61800‑5‑2):

Safety Integrated basic functions:

  • Safe Torque Off (STO)
    Prevention of unexpected startup by internal cancellation of the drive pulses.
  • Safe Brake Control (SBC)
    Safe brake control of holding brakes which are active in the de-energized state, e.g. motor holding brakes.
  • Safe Stop 1 (SS1)
    Safe stopping of the drive with subsequent prevention of unexpected startup (STO).

The Safety Integrated basic functions are license-free.

The basic functions of Safety Integrated are activated via the terminals of the SINAMICS S120 Combi Power Modules or the SINAMICS S120 Motor Modules in booksize compact format and SINUMERIK 828D.

Extended Safety Integrated functions:

  • Safe Operating Stop (SOS)
    Monitors drives for standstill. The drives remain fully functional in closed loop position control
  • Safe Stop 2 (SS2)
    Safe stopping of the drive with subsequent monitoring for standstill (SOS).
  • Safely Limited Speed (SLS)
    Monitoring of configurable velocity limit values, e.g. during setup.
  • Safe Speed Monitor (SSM)
    Safe checkback signal when a value falls below a settable speed limit, e.g. for enabling a protective door.
  • Safe Acceleration Monitor (SAM)
    Safe monitoring of drive acceleration.
  • Safe Direction (SDI)
    Safe monitoring of the direction of motion.
  • Safely Limited Position (SLP)
    Variable traversing range limitation
  • Safe Brake Management (SBM)
    • Safe Brake Control (SBC)
    • Safe Brake Test (SBT)

The Extended Safety Integrated functions require a software license in the form of a CNC option per axis/spindle with Safety functions.

A SINAMICS TM54F Terminal Module is required for controlling the Extended Safety Integrated functions.
