This function codes defines the V/F curve of
Goodrive20-EU motor 1 to meet the need of
different loads.
0: Straight V/F curve; applying to the constant
torque load
1: Multi-points V/F curve
2: Torque step-down V/F curve (1.3 order)
3: Torque step-down V/F curve (1.7 order)
4: Torque step-down V/F curve (2.0 order)
Curves 2–4 apply to the torque loads such as
fans and water pumps. Users can adjust
according to the features of the loads to get the
best performance.
5: Customized V/F (V/F separation); in this
mode, V can be separated from f and f can be
adjusted through
channel set by P00.06 or the voltage reference
channel set by P04.27 to change the feature of
the curve.
Note: V in the below picture is the motor rated
b
voltage and f is the motor rated frequency.
