Logic Operation Output Signal (Log1 To Log3) - Omron MX2 Series User Manual

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 P1/P2 Selection (C021/C022), or Multi-function Relay Output (MA, MB) 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.

Each logic operation output signal requires different parameter settings.
Set the necessary parameters according to the table below.
Selected signal
33: Logic operation output 1 (LOG1)
34: Logic operation output 2 (LOG2)
35: Logic operation output 3 (LOG3)
