Parameter
Control method switching by external terminals (X18 signal)
● Use the V/f switchover signal (X18) to change the control method (V/f control and General-
purpose magnetic flux vector control) with external terminal.
● Turn the X18 signal ON to change the currently selected control method (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. 182 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 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. 182 may affect the other functions.
Make setting after confirming the function of each terminal.
