When p9651 > 0: t_E = p9651 + 3 ms; p9651: Delays
2)
When p9651 = 0: t_E = 4 ms

When p10017 > 0: t_E = p10017 + 3 ms; p10017: Debounce time
1)
When p10017 = 0: t_E = 4 ms
T depends on how safety function SS1 is set:
2)
● SS1 with braking ramp monitoring: T = p9582 + time to brake down to standstill detection
● SS1 with acceleration monitoring: T = the lower of the two times:
– p9556
– Time to brake down to standstill detection
