These function codes define the V/F curve of CV50 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
th
2: 1.3 power low torque V/F curve
th
3: 1.7 power low torque V/F curve
th
4: 2.0 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 in the below picture is the motor rated voltage and
b
f is the motor rated frequency.
