Example Wiring Diagram Of Logic Connector Wiring - Omron MX2 User Manual

Connecting to PLCs and Other Devices
4-2-1 Example Wiring Diagram
Breaker, MCCB
or GFI
Power source,
3-phase or
1-phase, per
inverter model
Intelligent inputs,
7 terminals
Forward
NOTE:
For the wiring of intelligent
I/O and analog inputs,
be sure to use twisted
pair / shielded cable.
Attach the shielded wire
for each signal to its
respective common
terminal at the inverter
end only.
Input impedance of
each intelligent input is
4.7 kΩ
Thermistor
Short bar
(Source type)
GND for logic inputs
Freq. Meter
Volt. Meter
Analog reference
0~10VDC
4~20mA
Pulse train input
24 VDC 32 kHz max.
GND for analog signals
168
The schematic diagram below provides a general example of logic connector
wiring, in addition to basic power and motor wiring converted in Chapter 2.
The goal of this chapter is to help you determine the proper connections for
the various terminals shown below for your application needs.
