[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"
REMARKS
⋅ The control source of communication is as set in Pr. 550 and Pr. 551.
(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 operation
command source and speed command source. This signal can be utilized to control the signal input from both the
external terminal and communication.
⋅ Set "67" in any of Pr. 178 to Pr. 189 (input terminal function selection) to assign the X67 signal to the external
terminal.
⋅ When the X67 signal is off, the operation command source and speed command source are external.
X67 Signal State
No signal assignment
ON
OFF
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. Please
make setting after confirming the function of each terminal.
