Safety Integrated basic functions
10.7 Response times
Control of the Basic Functions via terminals on the Control Unit and Motor Module (CU310-2 and
CU320-2)
The following table lists the response times from the control via terminals until the response
actually occurs.
Table 10- 2 Response times for control via terminals on the Control Unit and the Motor Module.
Function
STO
SBC
SS1/SS1E (time-controlled)
Selection until STO is initiated
SS1/SS1E (time-controlled)
Selection until SBC is initiated
SS1 (time-controlled)
Selection until braking is initiated
The following applies for t_E (debounce time of the digital input being used):
1)
p9651 = 0
p9651 ≠ 0
The minimum time for t_E is t_E_min = 2 ms.

Worst case for a fault-free drive system Worst case when a fault exists
2 x r9780 + t_E
1)
4 x r9780 + t_E
1)
2 x r9780 + t_E + p9652
1)

1)
3 x r9780 + t_E + 2 ms
1)
t_E = p0799 (default = 4 ms)
1)
t_E = p9651 + 1 ms
