Trace evaluation:
● SLS function with SLS level 1 is active (see bits "deselection SLS", "selection SLS bit 0",
"selection SLS bit 1" and "SLS active", "active SLS level bit 0" and "active SLS level
bit 1")
● Drive is accelerated beyond the SLS limit (time axis from approx. -800 ms)
● Exceeding the limit is recognized (time axis 0 ms)
● Safety fault is initiated (time axis 0 ms; bit "internal event" is set to 0)
