14.1.22.3 Function 3: nIn1 < nIn2
This function serves, for instance, to implement the comparison "actual speed is lower
than a limit value" (n
act
< n
x
) for one direction of rotation.
[14-10] Function 3: Switching performance
Functional sequence
1. If the value at nIn1_a falls below the value at nIn2_a, bOut changes from FALSE to
TRUE.
2. Only if the signal at nIn1_a exceeds the value of nIn2_a - hysteresis again, bOut changes
back from TRUE to FALSE.
