When vector control cannot be programmed....
First read the precautions about vector control in section 6.3.9).
1) If the desired torque cannot be obtained  Refer to section 6.25 selection 2
2) If auto-tuning error "" appears  Refer to section 6.25 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.
Automatically programmed parameters

Displays  after resetting - Check the programmed value of . -

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 6.3
Note 7: To further increase torque, increase the torque boost value 1().
How to set the torque boost value 1()  Refer to section 6.4
Note 8: V/F control selection = 1 (variable torque) is an effective setting for load such as fans and
pumps.  Refer to section 6.3
