Description of Safety Integrated functions
4.2 Safety Integrated Extended Functions
Note
SBT and EPOS
If EPOS is activated, you must activate "follow-up mode" (r2683.0) before you perform the
brake test so that the position monitoring does not react during the brake test.
Note
SBT and DSC
If you use SBT with SIMOTION, evaluate parameter r10234 (S_ZSW3B) and activate Safety
Control Channel control word 3B (S_STW3B). In SIMOTION, r10234.1 specifies that no
position monitoring or traversing may be active during the brake test.
Note
SBT and HLA
The "Safe Brake Test" (SBT) function is not available for SINAMICS HLA.
