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.

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
