Trace evaluation:
● Function "SDI negative" is activated (see bits "Deselect SDI negative " and "SDI negative
active")
● The drive starts moving (time axis approx -220 ms)
● Exiting the SDI tolerance window is detected (time axis 0 ms)
● Safety messages are initiated (time axis 0 ms; bit "internal event" is set to 0)
● Error response STOP B is triggered (time axis 0 ms; see bit "SS1 active")
● The drive is braked to a standstill
● Shutdown speed is detected (time axis from approx. 25 ms)
● STOP A (as follow-up response to STOP B) is activated (see bit "pulse enable" = 1); at
this point, the speed falls below the shutdown speed SS1 (p9560/p9360) (speed drops
below the shutdown speed SS1 before SS1 timer p9556/p9356 has expired)
Note
Small time differences (of the order of 2 to 3 Safety clock cycles (here up to 7 ms)) are
caused by internal calculations and do not present a problem.
