Example Trace SS2
Figure 10-2 Example Trace SS2
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 of r9714[0] (orange curve) shows whether the OFF3 ramp is active
● SOS is activated (time axis approx. 500 ms; see bit "SOS active"); at this point the SS2
● Brown curve: Envelope curve of function SBR (r9714[1]); a fault is generated if this is
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.
