These function codes define the V/F curves of Goodrive3000 series motor 1 to meet different
requirements of load features.
0: Straight line V/F curve: suitable for constant torque load
1: Multi-dot V/F curve
2: Torque step-down V/F curve (power of 1.3)
3: Torque step-down V/F curve (power of 1.7)
4: Torque step-down V/F curve (power of 2.0)
Curves 2
–4 are suitable for variable torque load such as fans and water pumps. Users can adjust
according to load features to achieve the most effective energy saving.
5: Customized V/F curve (V/F separation)
V and F separate in the mode. The feature of the curve changes either by the frequency channel of
P00.06 adjusting F or by the voltage channel of P04.27 adjusting V.
Note: In the following figure, V
