(3) 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 (input terminal function selection) to assign the
function.
REMARKS
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 control and General-purpose magnetic flux vector control can not be switched while the inverter is running. In case control is
switched between V/F control and General-purpose magnetic flux vector control, only second function is selected.
NOTE
Changing the terminal assignment using Pr. 178 to Pr. 182 (input terminal function selection) may affect the other
functions. Make setting after confirming the function of each terminal.
