(N) Operation via communication and its settings Parameters
5 - 676
The setting is applied after an inverter reset or power-ON.

N644
Ethernet communication
check time interval

0
Ethernet communication is available, but the
inverter trips in the NET operation mode.
0.1 to 999.8 s
Set the interval of the communication check
(signal loss detection) time for all devices with IP
addresses in the range specified for Ethernet
command source selection (Pr. 1449 to Pr. 1454).
If a no-communication state persists for the
permissible time or longer, the inverter will trip.
9999 No communication check (signal loss detection)

Ethernet command source
selection IP address 1
0 0 to 255
To limit the network devices that send the
operation or speed command through the
Ethernet network (Modbus®/TCP or CCLink IE
Field Network Basic), set the range of IP addresses
of the devices. When Pr. 1449 to Pr. 1452 = "0
(initial value)", no IP address is specified for
sending commands through the Ethernet
network.
In this case, operation through the Ethernet
network (Modbus®/TCP or CC-Link IE Field
Network Basic) is not available. When four or
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
selection may be forced to be closed.

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).
