Description
0: Straight line
1: Multi-dots V/F curve, manually set V/F
curve through F04.03~F04.08
2: 1.3th power torque reduction V/F curve
3: 1.7th power torque reduction V/F curve
4: 2.0nd power torque reduction V/F curve
Curves 2~4 are suitable for water pumps
and users can choose them according to
load characteristics for best performance.
5: Custom V/F curve
In order to increase the starting torque of the

compensate for the low frequency output
voltage; The setting value is the percentage
of the motor rated voltage.
The percentage of the motor rated
frequency.
After the frequency reaches this value, the
torque lifting is cancelled.
