Safety Information
Safety Information
•Always follow safety instructions to prevent accidents and potentially hazardous
situations.
•Safety precautions are classified into “WARNING” and “CAUTION,” and their meanings
are as follows:
Indicates a potentially hazardous situation which, if not avoided, may cause death or
serious injury.
Indicates a potentially hazardous situation, which, if not avoided, may cause minor injury
or damage to the product.
•Symbols used in this document and on the product indicate the following.
Read and follow the instructions carefully to avoid dangerous situations.
Presence of "dangerous voltage" inside the product that may cause harm or
electric shock.
•Keep the operating instructions handy for quick reference.
•Read the operating instructions carefully to fully understand the functions of the H2
series inverters and use them properly.
•Be careful not to damage the CMOS elements on the communication board.
Static charge may cause malfunctioning of the product.
•Turn off the inverter before connecting communication cables.
Otherwise, the module may be damaged or a communication error may result.
•Correctly align the communication board to the installation connector for
installation and ensure that it is firmly connected to the inverter.
Otherwise, the module may be damaged or a communication error may result.

Overview
1 Overview
The Ethernet/IP & Modbus-TCP communication board allows the H2 inverter to be
connected to an EtherNet network that is compliant with international standards*. The
communication board supports two protocols: EtherNet/IP or Modbus TCP.
By utilizing the 100 Mbps auto negotiation feature, the communication board provides
real-time network communication without collisions and allows for controlling and
monitoring of the inverter via PLC sequence programs or a Modbus master module.
Compatible with H2 inverter S/W version 201.00 (parameter CNF-10).
Compatible with H2P inverter S/W version 202.00 (parameter CNF-10).
With simple network cable wiring, installation times can be reduced and maintenance
becomes easier.
*Ref.: IEC 61158 Type 21 , and IEC 62439, RRP.

Board Layout and Installation
④Install the H2 communication board to the right side of the control board
engaging the connector. Install screws (M3) in two places.
⑤Assemble the top cover, keypad, and front cover in reverse order of
disassembly.
* The installation method is the same for larger inverters (>150 HP, 110kW). Refer to the
H2 Instruction Manual for cover identification and removal.
•Do not install or remove the communication board to or from the H2 inverter while the
inverter is turned on.
•Ensure that the charge in the capacitors inside the inverter is completely discharged
before installing or uninstalling the communication board.

9.2 Configuration Group (CNF)
①[CNF-30] Option-1 Type: Display the type of option slot 1
It automatically displays the type of communication option board currently
installed in H2. When the communication option board is mounted in the H2
inverter, it is automatically displayed as name of the option board.
** Depending on the inverter version, it may be displayed as “Reserved-18” instead of
by name.
9.3 DRV Group
①[DRV-06] Cmd Source: Command Source
Select the command source for the H2 inverter. Set to “4 (Field Bus)" to set the
communication board as the command source and provide commands via
network.
②[DRV-07] Freq Ref Src: Frequency reference source
Select the frequency reference source for the H2 inverter. Set to “7 (Field
Bus)" to set the communication board as the frequency reference source and
provide the frequency reference via network.
9.4 COM Group
①[COM-06] FBus S/W Ver: Communication option S/W version
Automatically indicates the version of the communication board installed to the
H2 inverter.
②[COM-07] FBus ID: Station ID of the communication board
(communication board ID)
Set the station ID for the H2 communication board. A total of 255 station IDs
are available from 0 to 255. (The station ID must be set before you can
configure network communication using the protocol.)
When setting the station ID, be careful not to use a station ID that is not
already occupied by the PLC system or other network devices.
After making setting changes, you must set COM-94 (Comm Update) to “1
(Yes)” before the changes can take effect.
