Control of Basic Functions via PROFIsafe
The following table lists the response times from receiving the PROFIsafe telegram at the
Control Unit up to initiating the particular response.
Table 8- 4 Response times when controlling the Basic Functions via PROFIsafe
Function
STO
SBC
SS1 (time controlled)
Selection up until STO is initiated
SS1 (time controlled)
Selection up until SBC is initiated
Controlling the Extended Functions
The tables below show the response times, when functions STO, SS1, or SS2 are selected,
between recognition of the selection at the Control Unit and the initiation of the relevant
braking response. The entries for monitoring functions SOS, SLS, SAM, and SSM show the
time between when the relevant limit value is exceeded and when the response is initiated.
Control of Extended Functions with encoder via PROFIsafe
The following table lists the response times from receiving the PROFIsafe telegram at the
Control Unit up to initiating the particular response.
Table 8- 5 Reaction times when controlling the Extended Functions with encoder via PROFIsafe
Function
STO
SBC
SS1 (time and acceleration controlled), SS2
selection until braking initiated
SAM response of the safe acceleration
monitoring
SOS standstill tolerance window violated
SLS speed limit violated

3)
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.
