Note 1: Setting V/F control selection to (sensorless vector control) provides the same characteristics as

when

(auto-tuning) is set to 2.

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 "

" appears, see 6.13, 3.

(automatic torque boost) 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

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.

If V/F constant control is programmed after changing ,

Set V/F control mode selection to 0 (V/F constant)

 

 

See 5.12.

Note 1:

If you want to increase torque further, raise the setting value of manual torque boost .

 

How to set manual torque boost parameter

See 5.13.

Note 2:

V/F control selection to 1 (variable torque) is an effective setting for the load on such

 

equipment as fans and pumps.

See 5.12.
