Multi-function Compact Inverter 3G3MX2-EV2 User’s Manual (I666-E1)
Allocate the Multi-function Output 11/12 Selection (C021/C022) or Multi-function Relay Output (AL1,
AL2) Function Selection (C026) to 12 (ONT: Power ON time over).
Set the RUN Time/Power ON Time Detection Level (b034).
7-8-11 Logic Operation Output Signal (LOG1 to LOG3)
Use these signals to have the inverter internally perform logical operations with output signals. Set the
Multi-function Output 11/12 Selection (C021/C022), or Multi-function Relay Output (AL1, AL2)
Function Selection (C026), to 33 (LOG1: Logic operation output 1), 34 (LOG2: Logic operation output
2), or 35 (LOG3: Logic operation output 3). The logic output signal selection parameters cannot be
set to 255 (no: No allocation), 63 (OPO: Option), or 33 to 35 (LOG1 to LOG3: Logic operation output
1 to 3).
Three operators, AND, OR, and XOR, are available.
Logic output sig-
nal selection 1
Logic output sig-
nal selection 2
LOGx (AND)
LOGx (OR)
LOGx (XOR)
Each logic operation output signal requires different parameter settings.
Set the necessary parameters according to the table below.
