Control of Extended Functions with encoder via terminals (only CU310-2)

The table below shows the response times
until the response is initiated.
Table 8- 6 Response times when controlling the Extended Functions with encoder via safe onboard terminals (only
CU310-2)
Function
STO
SBC
SS1 (time and acceleration controlled),
SS1E (tme controlled),
SS2 selection until braking is initiated
SBR or SAM (limit value violation until STO active)
SOS standstill tolerance window violated
SLS speed limit violated
SSM
3)
SDI (limit value violation until braking is initiated)
The specified response times are valid for Extended Functions with and without selection!
1)
SLS: Specification of the response time required to initiate a braking response in the drive - or for the output of the "SOS
2)
selected" message to the motion control system.
SSM: The data corresponds to the times between the limit value being fallen below up to output of the information via

For p9511 = 0 If an isochronous PROFIBUS master is available:
Otherwise:
For t_E, the following applies:

p10017 = 0 t_E = 2 · p0799
p10017 ≠ 0 t_E = p10017 + p0799 + 1 ms
