Mitsubishi Electric FR-A820-00046 Instruction Manual page 883

Parameters
Ethernet IP address for command source selection (Pr. 1449 to Pr. 1454)
● 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 communi-
cation, the connection attempted from outside of the IP address range set for Ethernet command
source selection may be forced to be closed.
● The setting range for command source selection depends on the settings in Pr. 1451 and Pr. 1453,
and Pr. 1452 and Pr. 1454. (Either of the settings can be larger than the other in Pr. 1451 and
Pr. 1453, and Pr. 1452 and Pr. 1454.)
Example Setting example 1:
In this case, the IP address range for command source selection via Ethernet communication is
"192.168.x (1 to 3).xxx (100 to 150)".

Example Setting example 2:
In this case, the IP address range for command source selection via Ethernet communication is
"192.168.2.xxx (50 to 100)".
