Control Of Advanced Functions With Encoder Via Profisafe (Cu310-2 And Cu320-2) - Siemens SINAMICS S120 Function Manual

8.4.10 Control of Advanced Functions with encoder via PROFIsafe (CU310-2 and
CU320-2)
The following table lists the response times
Control Unit up to initiating the particular response.
Table 8- 10 Response times when controlling via PROFIsafe

SLP (limit value violation until a response is initiated)
SCA: Time between violation of a cam start or end
position and output of the feedback message in

The specified response times involve internal SINAMICS response times. Program run times in the F-host and the
1)
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.
