4.2.66 Logical output signal operation function (LOG1 to LOG6)
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.
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:
Selected signal
Operation-target 1
selection
Operation-target 2
selection
Operator
selection
33: Logical output signal 1 (LOG1) C142 C143 C144
34: Logical output signal 2 (LOG2) C145 C146 C147
35: Logical output signal 3 (LOG3) C148 C149 C150
36: Logical output signal 4 (LOG4) C151 C152 C153
37: Logical output signal 5 (LOG5) C154 C155 C156
38: Logical output signal 6 (LOG6) C157 C158 C159
(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)
