Vector Control Function Group：p2.00-P2.22 - HNC Electric HV590 Series User Manual

In the process of asynchronous complete tuning , asynchronous complete tuning is taken first, and
then accelerate to 80% of motor rated frequency according to P0.17. After keeping the state for a period
of time, then decelerate to stop according to P0.18 and stop tuning.
Before asynchronous complete tuning , users should set motor type and motor nameplate
parameters P1.00~P1.05 as well as encoder type and encoder pulse numbers P1.27、P1.28.
Inverter can get 5 motor parameters P1.06~P1.10 as well as AB phase sequence P1.30, vector
control current loop PI parameter P2.13~P2.16 from tuning.
Action description：Set P1.37 to 2 and then press RUN button, inverter will carry out asynchronous
complete tuning.

Users could choose different speed loop PI parameters under different running frequency. When
running frequency is less than the switching frequency(P2.02), adjusting parameters for speed loop PI are
P2.00 and P2.01. When running frequency is greater than the switching frequency (P2.02), adjusting
parameters for speed loop PI are P2.03 and P2.04. Speed loop PI parameters between switching
frequency1 and switching frequency2 are two groups of linear switching. As shown in fig.5.2：
PI parameter
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.
