: 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 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.
