5.11 Selecting control mode
 : V/F control mode selection
• Function
With HF-320 , the V/F controls shown below can be selected.
{V/F constant
{Variable torque
{Automatic torque boost control *1
{Sensorless vector control *1
{Automatic energy saving *1
{Dynamic automatic energy-saving (for fans and pumps)
(*1) "Automatic torque boost":  parameter can automatically set this parameter and auto-tuning at a time.
■ Parameter setting
Title Function Adjustment range Default setting
 V/F control mode selection 1
0: V/F constant
1: Variable torque
2: Automatic torque boost control
3: Sensorless Vector control
4: Automatic energy-saving

Steps in setting are as follows
(In this example, the V/F control mode selection parameter  is set to  (sensorless vector control).
[Setting V/F control mode selection to 3 (sensorless vector control)]
Key operated LED display Operation
. 
Displays the operation frequency. (Perform during operation stopped.)
(When standard monitor display selection  is set to 
[Operation frequency])

The first basic parameter “” (history function) is displayed.

Press the key to change the parameter to  (V/F control mode
selection).

Press the STR key to display the parameter setting. (Standard
default setting:  (automatic torque boost control)).

Press the key to change the parameter to  (vector control).
⇔ 
Press the STR key to save the changed parameter.  and
parameter set value “” are displayed alternately.
