V/F control parameters:P2.00-P2.15
Group P2 is valid only for V/F control.
The V/F control mode is applicable to low load applications (fan or pump) or applications where one
Inverter operates multiple motors or there is a large difference between the Inverter power and the motor
power.

•
0: Linear V/F
It is applicable to common constant torque load.
•
1: Multi-point V/F
It is applicable to special load such as dehydrator and centrifuge. Any such V/F curve can be
obtained by setting parameters of P2.03 to P2.08.
•
2: Square V/F
It is applicable to centrifugal loads such as fan and pump.
•
3 to 8: V/F curve between linear V/F and square V/F
•
10: V/F complete separation
In this mode, the output frequency and output voltage of the Inverter are independent. The output
frequency is determined by the frequency source, and the output voltage is determined by "Voltage
source for V/F separation" (P2.13).
It is applicable to induction heating, inverse power supply and torque motor control.
•
11: V/F half separation
