Logic Output Function

The Logic Output Function uses the inverter’s built-in logic feature. You can select any two of the other nine intelligent output options for internal inputs (use C141 and C142). Then, use C143 to configure the logic function to apply the logical AND, OR, or XOR (exclusive OR) operator as desired to the two inputs.

Intelligent outputs used as internal inputs:

RUN, FA1, FA2, OL, OD, AL, Dc, FBV, NDc
