Trace evaluation:
● SLS function with SLS level 2 is active (see bits "deselection SLS", "selection SLS bit 0",
● Drive is accelerated beyond the SLS limit (time axis from approx. -400 ms)
● Exceeding of the limit is recognized (time axis 0 ms)
● Safety fault is initiated (time axis 0 ms; bit "internal event" is set to 0)
● Fault response STOP B is initiated (time axis 0 ms; see bit "STOP A or B active" and
● Drive is decelerated to a standstill (see orange curve of r9714[0])
● Standstill reached (time axis from approx. 250 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) (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.
