Trace evaluation:
● SS2 function is selected (time axis 0 ms; see bit "deselection SS2")
● Response bit "SS2 active" is set (time axis approx. 20 ms)
● The drive decelerates along the configured OFF3 ramp (p1135)
● Recording r9714[0] (
● SOS is activated (time axis approx. 500 ms; see bit "SOS active"); at this point the SS2
timer (p9552) has expired

Time differences through internal c alculations
Small time differences (of the order of two to three safety cycles (here up to 36 ms)) are
caused by internal calculations and do not present a problem.
