Omron 3G3JX User Manual

In no event shall the responsibility of OMRON for any act exceed the individual price of the product on which liability is asserted. At the customer’s request, OMRON will provide applicable third party certification documents identifying ratings and limitations of use that apply to the products.

Performance data given in this manual is provided as a guide for the user in determining suitability and does not constitute a warranty. It may represent the result of OMRON’s test conditions, and the users must correlate it to actual application requirements. Indications and Meanings of Safety Information In this user’s manual, the following precautions and signal words are used to provide information to ensure the safe use of the 3G3JX Inverter.

The information provided here is vital to safety. Strictly observe the precautions provided.

Doing so might result in a small-scale fire, heat generation or damage to the unit. Install a stop motion device to ensure safety. Not doing so might result in a minor injury. A holding brake 3g3jc not a stop motion device designed to ensure safety. The material of the wall has to be nonflammable manyal as a metal plate. Precautions for Correct Use Warning Labels Warning labels are located on the Inverter as shown in the following illustration. Be sure to follow the instructions. Should you find any problems with the product, immediately contact your nearest local sales representative or OMRON sales office.

Understanding 33jx following configuration ensures more effective use of the product. Overview Chapter 1 Overview Describes features and names of parts. App-1 Appendix-2 Product Life Curve For factory maintenance only Communications connector Relay output terminal block Control circuit terminal block Main circuit terminal block output side S7: Not doing so may result in a serious injury due to an electric shock.


Wiring work must be carried out only by qualified personnel. Install the 3g3ix on a nonflammable wall surface material, like metal. After completing the installation process, be sure to remove the covers from the Inverter before operation.

Ventilation openings Both sides and top. Lift the bottom of the front cover to remove while holding the body. Loosen the front cover mounting screw.

Hang the upper side on the hooks. Connect securely to the ground as specified type-D grounding for V class, and type-C grounding for V class. Do not share the grounding electrode with other strong electrical devices.

Example of incorrect grounding Example of correct grounding Inverter Inverter Inverter External power supply input Manal source logic PNP: Power supply output Note: By factory default, the input logic of the multi-function input terminal circuit is set to the sink logic. The default setting is sink logic. When forcibly stopping the load with an MC on the primary side of the main manhal, however, the regenerative braking does not work and the load coasts to a stop free run.

A general-purpose noise filter will be less effective and may not reduce noise. Connect a noise filter to the output side of the Mabual to reduce induction and radio noise. Electromagnetic induction can generate noise on the signal line, causing the controller to malfunction. If the cable length is increased, the stray capacitance between the Inverter outputs and the ground is increased proportionally. An increase in stray capacitance causes high-frequency leakage current to increase, affecting the current detector in the Inverter’s output unit and peripheral devices.

At source logic mA max.


Contact The figure below illustrates the wiring of the sink logic. Below are the contact specifications of the relay output. Be sure to install it inside the control panel. Chapter 3 Operation Test Run Procedure Doing so may result in a serious injury due to an electric shock.
