power. The motor will enter into the weakening state when
the motor runs at rated speed. Change the weakening curve
by modifying the weakening control coefficient. The bigger
the weakening control coefficient is, the steeper the weak
curve is.

P03.24 set the Max. Voltage of the inverter, which is
dependent on the site situation.

Pre-exciting
time
Pre-activate the motor when the inverter starts up. Build up
a magnetic field inside the motor to improve the torque
performance during the starting process.

V/F curve
setting
These function codes define the V/F curve of Goodrive20
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 given channel set by P00.06 or the voltage given
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
