Power-on first run detection
The initial position angle detection is generally used for SVC. Its advantage is that it will not reverse when starting,
but the disadvantage is that there is a certain noise. For the occasions where reverse rotation is not allowed at
startup and the position of the motor rotor will change after stopping 02-25 Must be set to 0, otherwise it can be
set to 1 or 2.
You can set the detected current value through 02-24. The smaller the current is, the smaller the sound will be
during detection, but too small may cause inaccurate position detection.
03 V/f Control Parameters
Group 03 parameters are only valid for V/f control, not for vector control.

0: Straight line V/f. Suitable for ordinary constant torque loads.
1: Multi-point V/f. Suitable for special loads such as dehydrator and centrifuge. By setting 03-03~03-08
parameters, you can get any V/f curve.
2: Square V/f. Suitable for centrifugal loads such as fans and pumps.
3~8: V/f relationship curve between straight line V/f and 2.0th order V/f.
10: V/f complete separation mode. At this time, the output frequency of the inverter is independent of the output
voltage. The output frequency is determined by the frequency source, and the output voltage is determined by
03-13 (V/f separated voltage source).
This mode is generally used in induction heating, inverter power supply, torque motor control and other
occasions.
11: V/f half separation mode. In this mode, V and F are proportional, but the proportional relationship can be set
by voltage source 03-13, and the relationship between V and F is also related to the rated voltage and rated
frequency of motor group 01.
Assuming that the voltage source input is X (X is a value of 0~100%), the relationship between the output voltage
V of the inverter and the frequency F is:V/f=2 * X * (motor rated voltage)/(motor rated frequency)
