Output Logic and Timing

Logic Output Function – The inverter has a built-in logic output feature. You can select any two of the other nine intelligent output options for internal inputs. Then, configure the logic function to apply the logical AND, OR, or XOR (exclusive OR) operator as desired to the two inputs. The terminal symbol for the new output is [LOG]. Use C021, C022, or C026 to route the logical result to terminal [11], [12], or the relay terminals.
