If vector control cannot be programmed....
First read the precautions about vector control in 5.12, 6.
1) If the desired torque cannot be obtained, see 6.13, 3.
2) If auto-tuning error "

2) Increasing torque manually (V/F constant control)
The VF-S9 inverter is set to this control mode by factory default.
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.
