(N) Operation via communication and its settings
Error reset operation selection at inverter fault (Pr. 349)
In the External operation mode or the PU operation mode, use this parameter to disable an error reset
command sent through the Ethernet network (CC-Link IE Field Network Basic) or from a communi-
Pr. 349 setting
0 (initial value)
Tab. 5-228: Pr. 349 settings
Operation mode switching and communication startup mode (Pr. 79, Pr. 340)
● Operation mode switching conditions
– The inverter is at a stop.
– Both the STF and STR signals are off.
– The Pr. 79 "Operation mode selection" is correct.
(Set with the operation panel of the inverter) (refer to page 5-119).)
● The operation mode at power ON and at restoration from instantaneous power failure can be
selected. Set a value other than "0" in Pr. 340 "Communication startup mode selection" to select
the network operation mode (refer to page 5-128).
● After started in network operation mode, parameter write from the network is enabled.
Change of the Pr. 340 setting is valid when powering on or resetting the inverter.
Pr. 340 can be changed with the operation panel independently of the operation mode.
When setting a value other than 0 in Pr. 340, make sure that the communication settings of the
inverter are correct.
