Precautions for Safe Use
Precautions for Safe Use
Installation and Storage
Do not store or use the product in the following places.
• Locations subject to direct sunlight.
• Locations subject to ambient temperature exceeding the specifications.
• Locations subject to relative humidity exceeding the specifications.
• Locations subject to condensation due to severe temperature fluctuations.
• Locations subject to corrosive or flammable gases.
• Locations subject to exposure to combustibles.
• Locations subject to dust (especially iron dust) or salt.
• Locations subject to exposure to water, oil, or chemicals.
• Locations subject to shock or vibration.
Transportation, Installation, and Wiring
Observe the following instructions during transportation, installation, and wiring.
• Do not drop or apply a strong impact on the product. Doing so may result in damaged parts or
malfunction.
• Connect the DI Board to the Inverter tightly with the provided fixing screws.
Tighten securely the terminal screws for the signal wire on the DI Board.
Tightening torque: 0.9 N⋅m (1.0 N⋅m max.)
• Be sure to use the provided ferrite cores. Fix the ferrite cores on the wire or take appropriate
measures so that the ferrite cores will not cover the shield coating of the wire. Not doing so may
cause the Inverter to malfunction.
• Fix the shielding wire properly or take appropriate measures so that the wire will not be weighed
down.
Not doing so may result in shielding wire breakage due to the weight of the ferrite cores.

Overview
The DI Board (3G3AX-DI) is an optional board for the 3G3RX Series Inverter.
With this board, you can digitally input the set frequency, acceleration time setting, deceleration time
setting, torque setting and position (orientation stop position) setting.
Note that the PG Board (3G3AX-PG) is required separately for position control through position setting inputs.

2-5 Wiring
Applicable Wiring
Be sure to observe the following wiring conditions:
• For the signal line, use a shield wire of 0.5 mm
• Strip the signal line by 5 to 6 mm, and connect the exposed wire.
• In the case of stranded wires, make sure that the wires are not unraveled.
• Make sure that the maximum outside coating diameter of the signal line is 2.0 mm or less.
• Do not exceed 20 m for the wiring length of the shield wire.
The shield wire could be easily influenced by outside noise depending on the shielding method, resulting in an Inverter failure. Generally connect to the power supply ground of a signal line or to the
ground for shielding. (To connect to the ground, be careful of the ground cabling route, and avoid
multi-point grounding.)
Mounting the Ferrite Cores
The ferrite core mounting method is shown below.
Mount the two provided ferrite cores.
Connect the wire to the CM1 terminal of the 3G3AX-DI Board through the ferrite cores for shielding.

2-5 Wiring
If the ferrite cores cover the shield coating, they fail to work effectively, causing the Inverter to malfunction. Be sure to fix the ferrite cores or take other appropriate measures so that they do not overlap the shield coating.
The shield wire connected to the terminal could become disconnected due to the weight of the ferrite
cores. Be sure to fix the ferrite cores or take other appropriate measures so that the shield wire does
not receive the weight of the ferrite cores.

When setting the acceleration time to 60.0 sec with a resolution of 0.1 sec (Rotary switch setting
(CODE): 1,4,7,A)
1. Convert the value of 60 multiplied by 10 into the BCD binary value. Next, input the
MSB 2 digits in terminals D7 to D0, and input the acceleration time MSB code in terminals D15 to D8.
60 × 10 times = 600 → 0000011000000000 (binary)

2. When the data is entered, turn the strobe signal ON.
3. Turn the strobe signal OFF.
4. Input the rest of LSB 2 digits in terminals D7 to D0, and input the acceleration time
setting LSB code in terminals D15 to D8.

4-1 Precautions for Setting the Switches
Precautions for setting the switches are shown below.
Shut off the Inverter power and set appropriate settings.
When the rotary switch CODE is set to (5,7 to F: for factory adjustment) in the batch input mode,
a sequence error is output just after power is supplied to the Inverter.
When the rotary switch CODE is set to (C to F: for factory adjustment) in the dividing input mode,
a sequence error is output just after power is supplied to the Inverter.

4-2 Precautions for Data Input
4-2 Precautions for Data Input
Note the following items when inputting the data from the terminals of the 3G3AX-DI Board.
Each input can be set within the data range of the Inverter for each parameter.
If the data input is out of range, a sequence error will be output, and the data input will be disabled
(previous data retained).
Be sure to input type codes in the order of MSB to LSB in the dividing input mode.
If the LSB code is input first, a sequence error will be output, and the data input will be disabled
(previous data retained).
To reset the sequence error, input a correct data again, reset the Inverter, or shut off the power.
In the dividing input mode, if the two data inputs are correct, the sequence error will be reset just
after the second input.
If a code other than the type code is input, a sequence error will be output
The data input is disabled when the Inverter trips. Reset the Inverter and input again.
Do not set each command source of the Inverter (A001, P031, b040, P032) to “Option (1 or 2)”
for the port without the DI Board mounted. (Option 1 for Board port 1, 2 for Board port 2)

Maintenance Operations
Do not mount two DI Boards simultaneously. Doing so may result in malfunction.
The set values just after each command source of the Inverter (A001, P031, b040, P032) is set
to “Option (1 or 2)” are shown below.
Set frequency 0.00[Hz]

Certain Precautions on Specifications and Use
1. 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 PROPERLY RATED AND INSTALLED FOR THE INTENDED USE WITHIN THE
