*2 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 or TCP/IP) in any of Pr.1427 to Pr.1430.
*3 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 page
*4 The setting is available for the FR-E800-EPA.
*5 The setting is available for the FR-E800-EPB.
NOTE
• For details of communication protocols that cannot be used together, refer to
 Ethernet signal loss detection (Pr.1431, Pr.1457)
Use Pr.1431 and Pr.1457 to set the operation when Ethernet communication is interrupted by physical factors including
disconnection of the Ethernet cable or damages on the Ethernet cable.

When a signal loss is detected for both
8888 PORT1 and PORT2, the Pr.1431 setting
is applied.
When a signal loss is detected for either
9999 (initial
PORT1 or PORT2, the Pr.1431 setting
value)
is applied.
*1 The protective function is not activated while the inverter stops.
*2 The operation follows the Pr.502 Stop mode selection at communication error setting. (Refer to
NOTE
• For CC-Link IE TSN communication, a protective function (E.EHR) is activated regardless of the Pr.1431 and Pr.1457 settings
when a signal loss is detected during cyclic communication.
 Subnet mask (Pr.1438 to Pr.1441)
The subnet mask of the network to which the inverter belongs can be set in Pr.1438 to Pr.1441.
