Hz (Zs); Output Signal Logic Operation (Log1 To Log3) - Omron 3G3MX2 User Manual

5-9 Functions Relating to Protections, Warnings and Various Output Signals

0 Hz (ZS)

This function outputs a detection signal when the Inverter output frequency drops to below the
level set by 0 Hz Detection Level (C063).
This function is enabled when "21: ZS (0 Hz)" is allocated to any Multi-function Output Terminal
Selections (C021 to C022) or Multi-function Relay Output Function Selection (C026).
Although this function normally operates according to the Inverter output frequency, during
simple position control it operates according to the motor frequency.

Output Signal Logic Operation (LOG1 to LOG3)

This function performs output signal logic operations inside the Inverter. "No" (not assigned),
62, 63, and logic operation results (LOG1 to LOG3) cannot be selected.
Three types of operators, AND, OR and XOR, can be selected.
Output signal 1
Output signal 2
LOGx (AND)
LOGx (OR)
LOGx (XOR)
The setting parameters vary depending on the logic output signal selected.
Refer to the following table to set the necessary parameters.
33: Logic operation output 1 (LOG1)
34: Logic operation output 2 (LOG2)
35: Logic operation output 3 (LOG3)
