PARAMETERS
[Explanation of table]
External : Control is valid only from external terminal signal.
NET : Control only from communication is valid
Combined : Control is valid from either of external terminal and communication.
: Control is invalid from either of external terminal and communication.
Compensation: Control by signal from external terminal is only valid when Pr. 28 Multi-speed input compensation selection = "1"
(6) Switching of command source by external terminal (X67)
In Network operation mode, the command source switching signal (X67) can be used to switch the start command
source and speed command source. This signal can be utilized to control the signal input from both the 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 the X67 signal is off, the start command source and speed command source are control terminal.

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.

ON
OFF Command is valid only from control terminal signal.
REMARKS
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.
CAUTION
Changing the terminal assignment using Pr. 178 to Pr. 189 (input terminal function selection) may affect the other functions. Set
parameters after confirming the function of each terminal.
