Selecting control mode

: V/f control mode selection
• Function
With "VF-PS1," the V/f controls shown below can be selected.
0: Constant torque characteristics
1: Voltage decrease curve
2: Automatic torque boost (*1)
3: Sensorless vector control ( *1)
5: V/f 5-point setting
6: PM control ( *2)
7: PG feedback control ( *3)
9: Energy-saving
10: Advanced energy-saving
(*1) "Automatic control" parameter automatically sets this parameter and auto-tuning 1 at a time.
*
( 2) Unsupported.
*
( 3) A PG feedback device (optional) is needed for this control.

Title
V/f control mode selection
• When operating the inverter with
constant parameter correctly. Failure to do this may cause the inverter not to control the motor
Mandatory properly, and thus cause the motor not to deliver the desired performance. For more information,
see the explanation of each
1) Constant torque characteristics (Normal way of use)
Setting of V/f control mode selection
This is applied to loads with equipment like conveyors and cranes that require the same torque at low speeds as at
rated speeds.
Base frequency voltage 1
[V]/[%]
* To increase the torque further, increase the setting value of the manual torque boost parameter
