The logical output signal operation function allows you to make
the inverter internally perform a logical operation of output
signals.
This function applies to all output signals, except to logical
operation results (LOG1 to LOG6).
Three types of operators (AND, OR, and XOR) are selectable.
LOGx (AND)
LOGx (OR)
LOGx (XOR)
Output signal 1
Output signal 2
The necessary parameters depend on the logical output signal to be operated. The following table lists the
parameters to be set for each logical output signal:

(Example) To output the AND of the running signal (00: RUN) and set the frequency overreached signal
(02: FA2) as the logical output signal 1 (LOG1) to the intelligent output terminal [2]:
- Intelligent output terminal [2] (C002): 33 (LOG1)
- Logical output signal 1 selection 1 (C142): 00 (RUN)
- Logical output signal 1 selection 2 (C143): 02 (FA2)
- Logical output signal 1 operator (C143): 00 (AND)
