Detailed instruction of parameters
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
Note: P03.24–P03.26 are invalid for the vector
mode.

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.
These function codes define the V/F curve of
Goodrive300 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
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-consuming effect.
5: Customized V/F(V/F separation); on this mode,
V and F can be separated from adjusted through
the frequency given channel set by P00.06 or the
voltage given channel set by P04.27 to change
