Motor 1 V/F
curve setting
These function codes define the V/F curve of
Goodrive200A motor 1, and 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: 1.3
th
power low torque V/F curve
3: 1.7
th
power low torque V/F curve
4: 2.0
th
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 achieve a best
energy-saving effect.
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: V
b
in the below picture is the motor rated
voltage and f
