(N) Operation via communication and its settings
20
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
1432

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.

To limit the network devices that send the operation or speed
command through the Ethernet network (Modbus/TCP or CC-
Link 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.
