WARNING

• There is a risk of severe injury due to electric shock. After confirming that the power supply is OFF, wait at least 15 minutes and then perform wiring.
• There is a risk of severe injury due to electric shock. Wiring work must be carried out only by qualified personnel. Do not touch cables when the power supply is turned ON.
• There is a risk of severe injury due to electric shock. Do not operate the Communication Unit, LCD operator and switches with wet hands.
• There is a risk of severe injury due to electric shock. Do not perform maintenance while the power supply is ON.
• There is a risk of severe injury. For the Host Controller and Inverter programs, check the program contents and interactions between these programs before starting actual operation.
• There is a risk of severe injury. Do not enter the operating area during operation.

CAUTION

• The Inverter has high voltage parts inside which, if short-circuited, might cause damage to itself or other property. Place covers on the openings or take other precautions to make sure that no metal objects such as cutting bits or lead wire scraps go inside when installing and wiring.
• Be sure to confirm safety before conducting maintenance, inspection, or parts replacement.
• There is a risk of injury. Do not dismantle, repair, or modify the product.

Precautions for Safe Use

• Do not store or use the EtherCAT Communication Unit in the following environment:

• 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 near flammable materials

• Locations subject to dust (especially iron dust) or salts

• Locations subject to exposure to water, oil, or chemicals

• Locations subject to direct shock or vibration

• Do not directly touch the PCB connector of the Communication Unit as it may cause the Communication Unit to malfunction.

• During installation, wiring, and network setting on the Communication Unit, please refer to applicable sections of this manual to ensure the correct connection and configuration procedures.

• Take sufficient shielding measures when using the product in the following locations. Equipment damage may result.

  • Locations subject to static electricity or other forms of noise
  • Locations subject to strong magnetic fields
  • Locations close to power lines

• Fix the Inverter and the Communication Unit securely with the fixation screws. The Communication Unit may come off during operation due to vibration.

• If there is noise or other effects, install a ferrite core. When installing a ferrite core, do not allow the shielding sheath to be caught between the communications connector and the cable. Not doing so may cause an insufficient noise reduction effect, resulting in the Inverter malfunctioning.

• Fix the shield wire or use other means so that it is not subject to a heavy load. Shield wire breakage may occur due to the weight of the ferrite core.

• When transporting the Inverter with the EtherCAT Communication Unit mounted on it, be sure to hold the fins. Do not hold the front cover, terminal block cover, or Communication Unit. Doing so may cause the Inverter to fall.

• Do not drop or apply strong impact on the product. Doing so may result in damaged parts or malfunction.

• Be sure to tighten the FG terminal screw securely. Also, install the Inverter before wiring. There is a risk of a short circuit with energized parts if the FG wire is disconnected.

• Do not use a broken cable. If the ring is disconnected, the device may malfunction.

• Install an appropriate stopping device to ensure safety. In particular, if configured to operate continuously even in the event of a communications error, the Inverter may not stop, resulting in equipment damage.

• Be sure to confirm the RUN signal is turned off before resetting the alarm because the machine may abruptly start.

• The motor may start suddenly if voltage is accidentally applied to a control input terminal in a signal check when the power supply is ON. Ensure safety when you perform a signal check.

• Check the motor for the direction of rotation, abnormal noise, and vibration during operation.

• Be sure to confirm the permissible range of motors and machines before the operation because the speed can be set from low to high.
  A sudden parameter change may result in an unexpected operation.

• When the ring disconnection status occurs and then you reconnect an EtherCAT communications cable, turn OFF the power supply to the EtherCAT master and to the slaves. Connecting a faulty EtherCAT communications cable while the devices are in operation may stop the entire EtherCAT communications system.

Precautions for Correct Use

• If the ring disconnection status occurs, immediately perform an inspection and take appropriate measures. Equipment damage may result.
• Comply with the local ordinance and regulations when disposing of the product.

Precautions for Compliance with UL Standards and CSA Standards

Notice to Users of the 3G3AX-RX2-ECT in the USA and Canada. Please use the following installation information instead of the general information in the instruction manuals in order to use the product under certified conditions of UL and CSA when the product is installed in the USA or Canada. These conditions are required by NFPA 70, National Electrical Code in the USA and the Canadian Electrical Code, Part I in Canada and may vary from information given in the product manuals or safety precautions.

• Install device in pollution degree 2 environment.
• Maximum surrounding air temperature rating of 50°C

Conformance to EU Directives and UK legislations

• Please attach the ferrite core to each EtherCAT communications cable.
• This is a Class A product. In residential areas it may cause radio interference, in which case the user may be required to take adequate measures to reduce interference.

Overview

EtherCAT Communication Unit (3G3AX-RX2-ECT) can be installed in OMRON’s Inverters (RX2 series) to let you exchange various data with the host via EtherCAT.

The EtherCAT Communication Unit can be built into the following Inverters.

Inverter

Model| Manufacturer| Series
3G3RX2-£| OMRON| RX2 series

Specifications

powder, etc.)
Operating temperature| -10 to 50 °C
Humidity| 20 to 90 % (with no condensation)
Storage temperature| -20 to 65 °C
Weight| 100 g max.

Appearance and Names of Parts

For the overall depth when the EtherCAT Communication Unit is installed with an EtherCAT cable connected, add 76.2 mm to the dimension D of the Inverter. The dimension D differs depending on the capacity of the Inverter. Please refer to the manual for the Inverter.

Installation Procedure

1. Power down the Inverter. Wait for 15 minutes before mounting the Communications Unit.

2. Remove the Option Unit Connection Cover of SLOT 1.
   Note. Keep the cover you removed in a safe place.

3. Mount the Communication Unit. Fix it with the screw that is used for the Option Unit Connection Cover. Fixation screw: M3 x 14 Tightening torque: 0.6 to 0.8 N·m

4. Prepare an FG wire and wire it to a grounding location as close as possible to the FG terminal of the Communication Unit. FG terminal screw: M3 x 8 Tightening torque: 0.6 to 0.8 N·m.

5. Set necessary Inverter parameters.

   • When removing the Communication Unit, reverse the installation procedure.

Wiring Procedure

Securely connect the EtherCAT communication cable connector to the EtherCAT Communication Unit by inserting the connector all the way until it clicks. Connect the communication cable from the EtherCAT master side to the communication connector IN of the Communication Unit.

Connect the communication connector OUT to the communication connector IN of the next EtherCAT slave. Do not connect the communication connector OUT of the last EtherCAT slave.
Data will not be communicated correctly if the input/output are connected in reverse. For communication cables, be sure to use the Category 5 straight type or higher cables, double shielded by braid and aluminum tape.
