SBT Safe Brake Test
The implementation of safety concepts is facilitated significantly through the use of
drive-integrated safety engineering and its use also simplifies the verification of the
required safety category for a machine.
The user is also supported by the
In the current example, a SIMATIC F-CPU uses the PROFIsafe telegram with
PROFINET to control the safety functions. The SLS limit value input is
implemented using telegram 901 via the F-CPU.
PROFIsafe SLS Override
Version 1.0, Entry ID: 81682475
Function
The safety-relevant position values of the SINAMICS
S120 are transferred to a higher-level fail-safe control
system (F-CPU) using a PROFIsafe telegram
For safety functions without encoder, these are only
available with some restrictions.
Using this function, the holding torque of up to 2 (holding)
brakes can be tested.
In conjunction with the SBC function, a safety-relevant
brake can be implemented.
Not available for safety functions without encoder.
