Press the center of the setting dial to save the changed parameter.
and the parameter are displayed alternately.
If vector control cannot be programmed....
First read the precautions about vector control in section 5.12-9).
1) If the desired torque cannot be obtained ⇒ Refer to section 6.21 selection 2
2) If auto-tuning error "" appears ⇒ Refer to section 6.21 selection 4
(Torque boost setting macro function) and (V/F control mode
selection)
Automatic torque boost is the parameter for setting V/F control mode selection () and auto-tuning
() together. That is why all parameters related to change automatically when is changed.

4) Increasing torque manually (V/F constant control)
This is the setting of constant torque characteristics that are suited for such things as conveyors. It can also
be used to manually increase starting torque.
If V/F constant control is programmed after changing ,
Set V/F control mode selection = (V/F constant).
Refer to section 5.12.1)
Note 7: To further increase torque, increase the torque boost value 1().
How to set the torque boost value 1() Refer to section 5.13
Note 8: V/F control selection = 1 (variable torque) is an effective setting for load such as fans and
pumps. Refer to section 5.12.2)
