Example Trace SS1 with encoder
Figure 10-1 Example Trace SS1 with encoder
Trace evaluation:
● SS1 function is selected (time axis 0 ms; see bit "deselection SS1")
● Response bit "SS1 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
● STO is activated (time axis approx. 370 ms; see bit "STO active"); at this point the speed
● 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.

underranges the shutdown speed SS1 (p9560/p9360) (in this case shutdown speed SS1
is underranged before SS1 timer p9556/p9356 has expired)
exceeded by the actual speed (r9714[0])
