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.

Output signal 1

Output signal 2

LOGx (AND)

LOGx (OR)

LOGx (XOR)

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	Operation-target 2	Operator
	selection	selection	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)
