(5) Selection of command source in Network operation mode (Pr. 338, Pr. 339)
There are two control sources: operation command source, which controls the signals related to the inverter start
command and function selection, and speed command source, which controls signals related to frequency setting.
In Network operation mode, the commands from the external terminals and communication (RS-485 terminals or
communication option) are as listed below.

[Explanation of table]
External
: Command only from control terminal signal is valid.
NET
: Command only from communication is valid
Combined
: Command from either of external terminal and communication is valid.
: Command from either of external terminal and communication is invalid.
Compensation : Command by signal from external terminal is only valid when Pr. 28 Multi-speed input compensation selection = "1"
REMARKS
The command source of communication is as set in Pr. 550 and 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.
