11.2.2 Controlling the Basic Functions via PROFIsafe
The following table lists the response times

from receiving the PROFIsafe Telegram in the
drive up to initiating the particular response.

1)
The specified response times involve internal SINAMICS response times. Program run times in the F‑host and the
propagation time via PROFINET are not taken into account. When calculating the response times between 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.
2)
t_K is the time for internal communication within the SINAMICS module; t_K can be determined as follows:
t_K = To (for To, see parameter r2064[4])
