Setting range
Vector control current loop PI adjustment parameters. The complete tuning parameters in an
asynchronous machine or synchronous machine will automatically load after tuning, generally do not
need to modify.
What needs to be reminded is that the current loop integral controller, instead of using the
integration time as a dimension, but directly set the integral gain. PI current loop gain is set too high, it
may cause the entire control loop oscillation, so when current oscillations or torque ripple is large, it can
be reduced manually for PI proportional gain or integral gain here.
P3 group-V/F control parameters
The function code only for V / F control is effective. For vector control, it is invalid.
V / F control is suitable for fans, pumps and other general load, or a inverter with multiple motors, or
inverter power and motor power quite different applications.

range
0: Linear V / F. Suitable for ordinary constant torque load.
1: Multi-point V / F. Suitable for dehydration machines, centrifuges and other special loads. At this
time by setting P3-03 ~ P3-08 parameters, it can be obtained at any of VF curve.
2: Multi-point V / F. Suitable for fans, pumps and other centrifugal load.
3~8: VF curve between the straight line between the PF and VF square.
10: VF completely separate mode. Then the output frequency of the inverter output voltage
independent of each other, the output frequency is determined by the frequency source. But output
voltage is determined by P3-13 (VF isolated voltage source).
VF complete separation mode, Generally used in induction heating, power inverter, torque motor
control and other applications.
11: VF semi-separation mode.
In this case V and F are proportional, but proportional to the voltage source by setting P3-13, and
the relationship between V and F are also group P1 rated motor voltage related to the rated frequency.
