V/F curve
setting
These function codes define the V/F curve of
Goodrive20-UL motor 1 to meet the need of
different loads.
0: Straight line V/F curve; applying to the
constant torque load
1: Multi-dots V/F curve
2: 1.3th power low torque V/F curve
3: 1.7th power low torque V/F curve
4: 2.0th power low torque V/F curve
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
