NOTE
• The communication interface selection is determined by the setting of Pr.550 and Pr.551.
• The settings of Pr.338 and Pr.339 can be changed during operation when Pr.77 = "2". Note that the changed setting is applied
after the inverter has stopped. Until the inverter has stopped, the previous setting of the interface for the operation command
and the speed command in the Network operation mode is valid.
 Changing the command interface using a signal input via external
terminal (X67 signal)
• In the Network operation mode, the command interface for the operation command and the speed command can be
changed using the Command source switchover (X67) signal. This method may be useful to use both external terminal
and communication interface by using a different interface according to the command type.
• For the X67 signal, set "67" to any parameter from Pr.178 to Pr.184 (Input terminal function selection) to assign the
function to a control terminal.
• When the X67 signal is OFF, the command interface for the operation command and the speed command is the control
terminal.
X67 signal state
Signal not assigned
ON
OFF
NOTE
• The ON/OFF state of the X67 signal is applied only during a stop. When the terminals are switched during operation, the ON/
OFF state is reflected after a stop.
• When the X67 is OFF, a reset via communication is disabled.
• Changing the terminal assignment using Pr.178 to Pr.184 (Input terminal function selection) may affect the other functions.
Set parameters after confirming the function of each terminal.
