then accelerate to 80% of motor rated frequency according to F0.17. After keeping the state for a period
of time, then decelerate to stop according to F0.18 and stop tuning.
Before asynchronous complete tuning , users should set motor type and motor nameplate
parameters F1.00~F1.05 as well as encoder type and encoder pulse numbers F1.27

F1.28.
Inverter can get 5 motor parameters F1.06~F1.10 as well as AB phase sequence F1.30, vector
control current loop PI parameter F2.13~F2.16 from tuning.

Users could choose different speed loop PI parameters under different running frequency. When
running frequency is less than the switching frequency(F2.02), adjusting parameters for speed loop PI are
F2.00 and F2.01. When running frequency is greater than the switching frequency (F2.02), adjusting
parameters for speed loop PI are F2.03 and F2.04. Speed loop PI parameters between switching
frequency1 and switching frequency2 are two groups of linear switching. As shown in fig.5.2

Users can adjust vector control speed dynamic response characteristics through setting proportional
coefficient and integration time of the speed regulator.
Both increasing proportional gain and reducing integration time can accelerate the speed loop
dynamic response.But excessive proportional gain or insufficient integration time may led to system
oscillation.
Suggestions for regulating method
：
If the factory parameters can not meet the requirements, users can fine-tuning it on the basis of factory
value parameters. First increase the proportional gain to restrain system oscillation,then reduce integration
time so that system has fast response characteristic and smaller overshoot.
Notice
：
Improper PI parameter setting may lead to excessive speed overshoot , even volt age fault
during overshoot drop.
