Ethernet Function Selection; Communication Speed And Full-Duplex/Half-Duplex Selection - Mitsubishi Electric A800-E Instruction Manual

Ethernet function selection (Pr.1427 to Pr.1429)
Refer to the Instruction Manual of the device connected via Ethernet, and set Pr.1427 to Pr.1429 Ethernet function
selection 1 to 3 according to the application and protocol.
A communication socket is provided only for the selected application.


If both application and protocol settings are identical in Pr.1427 to Pr.1429, the priority of the setting is defined as follows: Pr.1427 > Pr.1428 >
Pr.1429.
(Example) When Pr.1427 = "5001", Pr.1428 = "5006", Pr.1429 = "5013", "5001" and "5013" are valid.

To connect the inverter and FR Configurator2 via the MELSOFT / FA product for Ethernet communication, set "5001 (initial value)" or "5002"
according to the protocol type (UDP/IP or TCP/IP) in any of Pr.1427 to Pr.1429.

When the inverter is connected with other equipment via a hub, and if the communication between the other equipment and the hub is
interrupted and resumed, the communication between the inverter and the other equipment may not be established depending on the
specifications of the hub. To re-establish communication with the other equipment, reset the inverter to forcefully close the connection. (Setting a
shorter time in Pr.1455 Keepalive time is also effective as a preventive measure (refer to

For details, refer to the Instruction Manual of FR Configurator2.
Communication speed and full-duplex/half-duplex selection (Pr.1426)
Set the communication speed and the communication mode (full-duplex/half-duplex) in Pr.1426 Link speed and duplex
mode selection.
If the operation is not performed properly in the initial setting (Pr.1426 = "0"), set Pr.1426 according to the specifications of the
connected hub.
