For the speed sensorless vector control, this
parameter is used to adjust the speed stability
accuracy of the motor. When the speed of the
motor is low when it is loaded, this parameter
will be increased, and vice versa. For vector
control with speed sensor, this parameter can
adjust the output current of inverter under the
same load.

It is only valid for vector control
and invalid for VF control. Running
at different frequencies, different
PI parameters of speed loop can be
selected. When the operating frequ-
ency is less than the switching fre-
quency 1, the PI adjustment parame-
ters of the speed loop are p2-01 and
p2-02. When the operating frequency
is greater than the switching frequ-
ency 2, the PI adjustment parameters
of the speed loop are p2-04 and p2-05.
The PI parameters of speed loop bet-
ween switching frequency 1 and swit-
ching frequency 2 are linear swit-
ching of two groups of PI parameters.
By setting the proportional coeffi-
cient and integral time of the speed
regulator, the dynamic response cha-
racteristics of the vector control
can be adjusted. The dynamic response
of the speed loop can be accelerated
by increasing the proportional gain
and reducing the integration time.
However, if the proportional gain is
too large or the integration time is
too small, the system may oscillate.
