If vector control cannot be programmed....
First read the precautions about vector control in 5.11, 8.
1) If the desired torque cannot be obtained
2) If auto-tuning error "

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

(automatic torque boost) and
Automatic torque boost is the parameter for setting V/F control mode selection 1 (
tuning ( ) together. That is why all parameters related to change automatically when
changed.
