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.
The following table shows all four possible logic input combinations with each of the
three available logical operations.
