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.
