V/F curve
setting
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 the frequency reference
channel set by P00.06 or the voltage reference
channel set by P04.27 to change the feature of
the curve.
Note:
