3.5.2 Response times, Safety Integrated Extended Functions with encoder
Activation of Extended Functions with encoder via PROFIsafe
The following table lists the response times from receiving the PROFIsafe telegram on the
Control Unit up to initiating the response.

The specified response times involve internal SINAMICS response times. Program run times
in the F host and the transmission time via PROFIBUS or PROFINET are not taken into
account.
Activation of Extended Functions with encoder via TM54F
The following table lists the response times between a signal occurring at the terminals up to
the initiation of the response.
