Select V/f #1 when using the sensor-less vector control or the V/f 5-point setting.
Selecting V/f #2, #3 or #4 disables the vector control but enables the V/f constant control.
In addition, if the torque limit switching function and the acceleration/deceleration
switching function are assigned to input terminals, their settings are valid.
Note) With the control panel or communication, the following parameters can be set individually:
V/f switching ()
Acceleration/deceleration switching()
Torque limit switching()
These functions are active only in control panel operation mode.
