External : Command is valid only from signal of external terminal.
NET : Command is valid only from communication.
Combined : Command is valid from either of control terminal or communication.
— : Command is valid from both control terminal or communication.
Compensation : Command is valid by signal from external terminal if [Pr. 28 Multi-speed input compensation selection = 1].

(6) Command source switchover by external
terminal (X67 signal)
In the network operation mode, the command source
switching signal (X67) switches start command
source and frequency command source. This
function is useful when controlling signal input from
both of control terminal and communication.
Set 67 in any of [Pr. 178 to Pr. 189 Input terminal
function selection] to assign the X67 signal to the
control terminal.
When X67 signal is OFF, control terminal has the
start command source and frequency command
source.

The ON/OFF state of the X67 signal is reflected only
during a stop. It is reflected after a stop when the
terminal is switched during operation.
When the X67 signal is OFF, a reset via
communication is disabled.

To make communication between the personal computer
and inverter, initialization
specifications must be made to the inverter. Data
communication cannot be made if the initial settings are
not made or there is any setting error.
Always reset the inverter after making the initial settings of
the parameters.

be made until the inverter is reset.

Set the inverter station numbers when two or more inverters
are connected to one personal computer.
