•

Install the Inverter under the following conditions.

Ambient temperature for operation (panel-mounting): –10

C to 50

Humidity: 95% or less (no condensation)

•

Install the Inverter in a clean location free from oil mist and dust. Alternatively, install it in a totally enclosed panel that is completely protected from floating dust.

•

When installing or operating the Inverter, always take special care so that metal powder, oil, water, or other foreign matter does not get into the Inverter.

• Do not install the Inverter on inflammable material such as wood.

Direction

•

Install the Inverter on a vertical surface so that the characters on the nameplate are oriented upward.

Air

Ambient Temperature Control

•

To enhance operation reliability, the Inverter should be installed in an environment free from extreme temperature changes.

•

If the Inverter is installed in an enclosed environment such as a box, use a cooling fan or air conditioner to maintain the internal air temperature below 50

The life of the built-in electrolytic capacitors of the Inverter is prolonged by maintaining the internal air temperature as low as possible.

•

The surface temperature of the Inverter may rise approximately 30

C higher than the ambient temperature. Be sure to keep away equipment and wires from the Inverter as far as possible if the equipment and wires are easily influenced by heat.

Protecting Inverter from Foreign Matter during Installation

•

Place a cover over the Inverter during installation to shield it from metal power produced by drilling.

Upon completion of installation, always remove the cover from the Inverter. Otherwise, ventilation will be affected, causing the Inverter to overheat.

2-1-2 Accepting Operation Commands While Changing

Parameters

With the default settings, the Inverter will not accept operation commands when parameter settings are being changed. This functions as a safety measure to prevent the motor from rotating if the operation command is mistakenly set to ON when changing parameters.

Depending on the operating conditions, however, the user may want to have operation commands accepted even while parameters are being changed. In that case, change the following settings.

Using the Indicators to Determine When Operation Commands Can Be

Accepted

The indicators on the Digital Operator can be used to determine if operation commands will be accepted or not while changing parameters.

Green: Operation commands will be accepted if the indicator lights green.

Red: Operation commands will not be accepted after the Inverter stops if an indicator lights red.

Therefore, if the indicator lights red when changing parameters or when switching between local and remote operation, operation will continue, but once the Inverter stops, the Inverter will not operate even if the operation command is set to ON again.

The FREF indicator will light when the power supply is turned ON.

The default value for n01 is 1.

Operation commands will not be accepted when n01 itself is being changed.

Some parameters cannot be changed during operation. Those parameters cannot be changed during operation even if the setting for n01 is changed.

When n01 is changed to 5, an operation command will be accepted even when changing parameters, such as during trial operation. Thoroughly check safety before changing any setting.

Chapter 2

The 3G3IV-PJVOP140 and 3G3IV-PJOP146 Digital Operators contain an EEPROM.

All Inverter parameter settings, the Inverter capacity, and the software number are recorded in this EEPROM. The EEPROM can be used to copy parameter settings to other

Inverters.

Parameter settings can be copied between Inverters with the same power supply specifications, but some of the parameter settings are not copied.

4-1-1 Fault Detection (Fatal Error)

The Inverter will detect the following faults if the Inverter or motor burns or the internal circuitry of the Inverter malfunctions. When the Inverter detects a fault, the fault code will be displayed on the Digital Operator, the fault contact output will operate, and the

Inverter output will be shut off causing the motor to coast to a stop. The stopping method can be selected for some faults, and the selected stopping method will be used with these faults. If a fault has occurred, refer to the following table to identify and correct the cause of the fault. Use one of the following methods to reset the fault after restarting the

Inverter. If the operation command is being input, however, the reset signal will be ignored. Therefore, be sure to reset the fault with the operation command turned off.

Turn on the fault reset signal. A multi-function input (n36 to n39) must be set to 5 (Fault

Reset).

Certain Precautions on Specifications and Use

Suitability of Use. Omron Companies shall not be responsible for conformity with any standards, codes or regulations which apply to the combination of the

Product in the Buyer’s application or use of the Product. At Buyer’s request,

Omron will provide applicable third party certification documents identifying ratings and limitations of use which apply to the Product. This information by itself is not sufficient for a complete determination of the suitability of the Product in combination with the end product, machine, system, or other application or use. Buyer shall be solely responsible for determining appropriateness of the particular Product with respect to Buyer’s application, product or system.

Buyer shall take application responsibility in all cases but the following is a non-exhaustive list of applications for which particular attention must be given:

(i) Outdoor use, uses involving potential chemical contamination or electrical interference, or conditions or uses not described in this document.

(ii) Use in consumer products or any use in significant quantities.

(iii) Energy control systems, combustion systems, railroad systems, aviation systems, medical equipment, amusement machines, vehicles, safety equipment, and installations subject to separate industry or government regulations.

(iv) Systems, machines and equipment that could present a risk to life or property. Please know and observe all prohibitions of use applicable to this Product.

NEVER USE THE PRODUCT FOR AN APPLICATION INVOLVING SERIOUS

RISK TO LIFE OR PROPERTY OR IN LARGE QUANTITIES WITHOUT

ENSURING THAT THE SYSTEM AS A WHOLE HAS BEEN DESIGNED TO

ADDRESS THE RISKS, AND THAT THE OMRON’S PRODUCT IS PROP-

ERLY RATED AND INSTALLED FOR THE INTENDED USE WITHIN THE

OVERALL EQUIPMENT OR SYSTEM.

Programmable Products. Omron Companies shall not be responsible for the user’s programming of a programmable Product, or any consequence thereof.

Performance Data. Data presented in Omron Company websites, catalogs and other materials 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 user must correlate it to actual application requirements. Actual performance is subject to the Omron’s Warranty and Limitations of Liability.

Change in Specifications. Product specifications and accessories may be changed at any time based on improvements and other reasons. It is our practice to change part numbers when published ratings or features are changed, or when significant construction changes are made. However, some specifications of the Product may be changed without any notice. When in doubt, special part numbers may be assigned to fix or establish key specifications for your application. Please consult with your Omron’s representative at any time to confirm actual specifications of purchased Product.

Errors and Omissions. Information presented by Omron Companies has been checked and is believed to be accurate; however, no responsibility is assumed for clerical, typographical or proofreading errors or omissions.
