The setting is applied after an inverter reset or power-ON.
NOTE The monitored items and parameter settings can be read during communication with the Pr.1432
Ethernet communication check time interval = "0" setting, but an inverter fault occurs instantly
when the operation mode is switched to the NET operation mode. When the NET operation mode
is selected as the start-up operation mode, communication is performed once, then an Ethernet
communication fault (E.EHR) occurs.
To perform operation or parameter writing via communication, set Pr.1432 to "9999" or a value
larger than the communication cycle or retry time setting (refer to page 5-682).

If a no-communication state persists for the

(When Pr. 1442 to Pr. 1445 = "0 (initial value)", the
function is invalid.)

To limit the network devices that send the
0 0 to 255
operation or speed command through the
Ethernet network (Modbus®/TCP or CCLink IE
Field Network Basic), set the range of IP addresses
0 0 to 255
of the devices. When Pr. 1449 to Pr. 1452 = "0
(initial value)", no IP address is specified for
0 0 to 255
sending commands through the Ethernet
network.
0 0 to 255
In this case, operation through the Ethernet
network (Modbus®/TCP or CC-Link IE Field
Network Basic) is not available. When four or
9999 0 to 255, 9999
more clients attempt a connection to the inverter
during Modbus®/TCP communication, the
connection attempted from outside of the IP
address range set for Ethernet command source
9999 0 to 255, 9999
selection may be forced to be closed.
