Setting of switching terminals
The V/f1, V/f2, V/f3 and V/f4 switching function is not yet assigned to any terminal. Therefore, it is necessary to
assign them to unused terminals.
Ex.) Assigning the V/f switching 1 function to S1 and the V/f switching 2 function to S2.

+Select V/f1 when using the vector control and the V/f-5 point setting.
Selecting V/f2,.V/f3, or V/f4 disables vector control but enables the V/f constant control.
+ By using “My function,” torque limits and acceleration/deceleration modes can be switched along with V/f
switching.
Note:With the operation panel or communication, the acceleration/deceleration switching (H) can be set.
* This function is active only in operation panel operation mode.
