The Logic Output Function uses the inverter's built-in logic feature. You can select any two of
the other intelligent output options for use as internal inputs to the logic function. You may also
select from three logical operators AND, OR, or XOR (exclusive OR), to be applied to the two
inputs. A total of six outputs are available, shown in the following tables.

The example below shows a configuration for [LOG1] Logic Output 1. Parameters C142 and
C143 contain option codes for two outputs we select to be used as inputs to the logic operation.
Parameter C144 contains the select code for the logic operation. 00=AND, 01=OR, and
02=OR.
Intelligent outputs used as internal
inputs: RUN, FA1, FA2, OL, OD, etc.:
[RUN] = option code 00
[FA2] = option code 02

The inverter calculates the capacitor life remaining based on the internal temperature of the
inverter and the cumulative power-ON time. The [WAC] Capacitor Life Warning output turns
ON to indicate that the capacitors have reached end-of-life. If this event occurs, Hitachi
recommends that you replace the main circuit board and logic circuit board. You may also use
monitor parameter D022 at the digital operator to monitor the status of capacitor life.
