Control mode
Control method switching by external terminals (X18 signal)
● Use the V/F switchover signal (X18) to change the control method (between V/F control and
Advanced magnetic flux vector control (General-purpose magnetic flux vector control)) with
external terminal.
● Turn the X18 signal on to change the currently selected control method (advanced magnetic flux
vector control or general-purpose magnetic flux vector control) to V/F control.
For the terminal used for X18 signal input, set "18" in any of Pr. 178 to Pr. 184 "Input terminal function
selection" to assign the function.
NOTES Switch the control method using external terminal (X18 signal) during an inverter stop. If control
method between V/F control and Advanced (General-purpose) magnetic flux vector control is
switched during the operation, the actual switchover does not take place until the inverter stops.
In addition, if control method is switched to V/F control during the operation, only second func-
tion becomes valid as V/F control and second functions are selected simultaneously in V/F control.
Changing the terminal assignment using Pr. 178 to Pr. 184 "Input terminal function selection" may
affect the other functions. Make setting after confirming the function of each terminal.
