2.3 Controlling the Safety Integrated functions

2.3 Controlling the Safety Integrated functions
The Safety Integrated functions can be controlled via terminals, via a PROFIsafe telegram
using PROFIBUS or PROFINET or, for the Extended Functions, via the TM54F Terminal
Module. In this case, control via terminals and TM54F or terminals and PROFIsafe can be
simultaneously selected.
NOTICE
Safety Integrated functions with SIMOTION
PROFISafe via PROFINET is not permitted with SIMOTION.
NOTICE
PROFIsafe or TM54F
Using a Control Unit, control is possible either via PROFIsafe or TM54F. Mixed operation is
not permissible
If induction motors are used, certain Safety Integrated functions can also be used without an
encoder. In encoderless operation the speed actual values are calculated from the measured
electrical ACTUAL values. As a consequence, speed monitoring down to n = 0 rpm is also
possible in encoderless operation.
