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

(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.

