7.8.12 Logical output signal operation function (LOG1)
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) and allocation none
(NO).
Three types of operators (AND, OR, and XOR) are selectable.

Operation-target 1

33: Logical output signal 1 (LOG1) C142 C143 C144
(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 [11]:
- Intelligent output terminal [11] (C021): 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 (C144): 00 (AND)
