Description
Reactivate the motor when the VFD starts up.
Build up a magnetic field inside the VFD to
improve the torque performance during the
starting process.
The setting time: 0.000–10.000s
0–8000

0.0–100.0%
Adjust P03.28 to compensate the coefficient of
static friction. Only valid when setting in 1Hz.
0.0–100.0%
Adjust P03.29 to compensate the coefficient of
static friction. Only valid when setting in 1Hz.
Description
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
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
b
voltage and f is the motor rated frequency.
