Safety Integrated Functions
8.9 Acceptance test and acceptance report
Trace evaluation:
● SLS function with SLS level 1 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 A is initiated (time axis 0 ms; see bit "STOP A or B active" and
● Drive coasts down (see Drive_1.r9714[0])
Note
Small 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.
