(4) Selection of control source in network operation mode (Pr. 338, Pr. 339)
As control sources, there are the operation command source that controls the signals related to the inverter start
command and function selection and the speed command source that controls the signals related to frequency setting.
In network operation mode, the commands from the external terminals and communication are as listed below.
[Explanation of table]
External : Command is valid only from control terminal.
NET : Command only from communication is valid
Combined : Command from both control terminal and communication is valid.
—
: Command from either of control terminal and communication is invalid.

REMARKS
The command source of communication is as set in Pr. 551 .
The Pr. 338 and Pr. 339 settings can be changed while the inverter is running when Pr. 77 = "2". Note that the setting change is
reflected after the inverter has stopped. Until the inverter has stopped, communication operation command source and
communication speed command source before the setting change are valid.
