Control mode
Control method switching by external terminals (X18 signal)
● Use the V/f switchover signal (X18) to change the control method (V/f control-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 When V/f control is selected by V/f switchover (X18 signal), second function is also selected
at the same time. Control between V/f and advanced (general-purpose) magnetic flux can
not be switched while the inverter is running. In case control is switched between V/f and
advanced (general-purpose) magnetic flux, only second function is selected.
Changing the terminal assignment using Pr. 178 to Pr. 184 "Input terminal function selec-
tion" may affect the other functions. Make setting after confirming the function of each termi-
nal.
