Communication operation and setting Parameter

햲
The setting is applied after an inverter reset or power-ON.
844
Ethernet command source
selection IP address 1
햲
0 0–255
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. 844 to Pr. 847 = "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 forcibly closed.

When the inverter does not receive a packet within
the time calculated by multiplying the Pr. 850
setting by 8 in seconds from the devices with the
TCP connection established, the connection will be
forcibly closed.

0
Signal loss detection
disabled
Set the availability of
the signal loss detection
and select the action
when Ethernet
communication is
interrupted by physical
factors.
2
The alarm (LF) signal is
output for a signal loss.
3
A protective function
(E.OP1) is activated for a
signal loss.
852
Ethernet communication
check time interval
1.5 s
0
Ethernet communication is available, but the
inverter output is shut off in the NET operation
mode.
0.1–999.8 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. 844 to Pr. 849). If a no-
communication state persists for the permissible
time or longer, the inverter output is shut off
9999 No communication check (signal loss detection)
NOTE The monitored items and parameter settings can be read during communication with the Pr. 852
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 the Ethernet
communication fault (E.OP1) is activated.
To perform operation or parameter writing via communication, set Pr. 852 to "9999" or a value
larger than the communication cycle or retry time setting (refer to page 6-290).
