8.4.4 Control of Extended Functions with encoder via PROFIsafe (CU310-2 and
CU320-2)
The following table lists the response times

STO
SBC
SS1 (time controlled), SS1E, SS2E: Time from select-
ing up to starting the safe timer
SS1 (acceleration controlled), SS2: Time from select-
ing up to initiating braking
SOS: Time from selecting up to starting standstill
monitoring
SBR or SAM (limit value violation until STO is active)
SOS standstill tolerance window violated
SLS speed limit violated

SDI (limit value violation until braking is initiated)
SLP (limit value violation until a response is initiated)
The specified response times are valid for Extended Functions with and without selection.
1)
The specified response times involve internal SINAMICS response times. Program run times in the F-host and the
2)
transmission time via PROFIBUS or PROFINET are not taken into account. When calculating the response times be-
tween the F-CPU and the converter, you must take into account that faults in the communication can result in a safety
function only being selected after the PROFIsafe monitoring time (F_WD_Time) has expired. The PROFIsafe monitoring
time (F_WD_Time) must also be included in the calculation when an error occurs.
SLS: Specification of the response time required to initiate a braking response in the drive - or for the output of the "SOS

For p9511 = 0 If an isochronous PROFIBUS master is available:
Otherwise:
t_K is the time for internal communication within the SINAMICS module; t_K can be determined as follows:

For isochronous communication
For non-isochronous
communication
p2048 applies to communication via IF1, p8848 to communication via IF2.
