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.

These function codes define the V/F curve of
Astraada DRV-24 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
