17.1.23.1 Function 1: nIn1 = nIn2
This function compares two signals with regard to equality. It can, for instance, provide the
comparison "actual speed equals setpoint speed" (n
act
=n
set
).
•Use C00682
to set the window within which the equality is to apply.
•Use C00681
to set a hysteresis if the input signals are not stable and the output oscillates.
