• 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.)
[Setting example 1]
Ethernet IP address
for command source selection
Command source selection range setting
for the Ethernet IP address
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)".
[Setting example 2]
Ethernet IP address
for command source selection
Command source selection range setting
for the Ethernet IP address
In this case, the IP address range in which Ethernet communication is permitted is "192.168.2.xxx (50 to 100)".
• When "9999 (initial value)" is set in Pr.1453 or Pr.1454, the range is invalid.
 Ethernet communication check time interval (Pr.1432)
• If a signal loss (communication stop) is detected between the inverter and all the devices with IP addresses in the range
for Ethernet command source selection (Pr.1449 to Pr.1454) as a result of a signal loss detection, a communication error
(E.EHR) occurs and the inverter output will be shut off.
• When "9999" is set in Pr.1432, the communication check (signal loss detection) will not be performed.
• The monitor items and parameter settings can be read via Ethernet when "0" is set in Pr.1432, but a communication error
(E.EHR) occurs instantly when the operation mode is switched to the Network operation.
• A signal loss detection is made when any of 0.1 s to 999.8 s is set in Pr.1432. In order to enable the signal loss detection,
data must be sent by connected devices at an interval equal to or less than the time set for the communication check. (The
inverter makes a communication check (clearing of communication check counter) regardless of the station number setting
of the data sent from the master).
• Communication check is started at the first communication when the inverter operates in the Network operation mode and
the command source is specified as communication via the Ethernet connector.
