Control mode
4.3.1 Changing the control method (Pr. 80, Pr. 81, Pr. 800)
∗
Set a value other than "9999" in Pr. 80 and Pr. 81 .
(1) Setting of the motor capacity and the number of motor poles
(Pr. 80, Pr. 81)
Motor specifications (motor capacity and number of motor poles) must be set to select Advanced magnetic flux vector
control or General-purpose magnetic flux vector control.
Set the motor capacity (kW) in Pr. 80 Motor capacity and set the number of motor poles in Pr. 81 Number of motor poles .
(2) Selection of control method
Select the inverter control method for V/F control, Advanced magnetic flux vector control, and General-purpose magnetic
flux vector control.
∗
Control method is V/F control regardless of the setting value of
Pr. 800
when "9999" is set in
Pr. 80 Motor capacity
or
Pr. 81 Number of motor poles
.
(3) 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.
Set when selecting the control method for Advanced magnetic flux vector control and General-purpose magnetic flux
vector control. The initial value is V/F control.
Select a control mode using Pr. 800 Control method selection .

REMARKS
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 function
becomes valid as V/F control and second function are selected simultaneously in V/F control.
NOTE
Changing the terminal assignment using Pr. 178 to Pr. 184 (input terminal function selection) may affect the other
functions. Set parameters after confirming the function of each terminal.
