Trace evaluation:
● SOS function is activated (see bits "deselect SOS" and "SOS active")
● The drive starts moving (time axis approx -100 ms)
● Exiting the SOS tolerance window is recognized (time axis approx 0 ms)
● Safety fault is initiated (time axis approx. 0 ms; bit "internal event" is set to 0)
● Fault response STOP B is initiated (see bit "STOP A or B active" and "SS1 active")
● The drive is decelerated to a standstill
● Standstill reached (time axis approx. 200 ms)
● STOP A (as follow-up response to STOP B) is activated (see bit "STO active"); at this

point the speed falls below the shutdown speed SS1 (p9560/p9360) before the SS1 timer
(p9556/p9356) has expired (drops below the shutdown speed SS1 before SS1 timer
(p9556/p9356) has expired)
Note
Minor time differences (of the order of 2 to 3 Safety clock cycles (here up to 36 ms)) are
caused by internal calculations and do not present a problem.
