PARAMETERS
(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 drive unit start
command and function selection, and speed command source, which controls signals related to speed setting.
In Network operation mode, the commands from the external terminals and communication (PU connector or
communication option) 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.550 and Pr.551.
The Pr.338 and Pr.339 settings can be changed while the drive unit is running when Pr.77 = "2". Note that the setting change is
reflected after the drive unit has stopped. Until the drive unit has stopped, communication operation command source and
communication speed command source before the setting change are valid.
