By adjusting the proportion coefficient and integral time of speed regulator, the
dynamic response speed of vector control can be adjusted. Increase proportional
gain and reduce integral time can both speed up the dynamic response of speed loop.
The conditions of too large proportional or too short integral time will cause system
oscillation.
Recommended adjustment method:
If the factory parameters cannot meet the requirements, conduct trimming on the
basis of factory parameters, firstly increase the proportional gain and ensure that the
system will not oscillate, then reduce integral time so that the system owns fast
response and small overshoot.
Note: Inappropriate setting of PI parameters will lead to large speed overshoot, even
cause over-voltage fault when overshoot falls back.
As for no speed sensor vector control, this parameter is used for adjusting rotating
speed of electric motor. When the work load of electric motor is heavy and the
speed is too slow, increase this parameter, contrarily decrease this parameter.
As for speed sensor vector control, this parameter can adjust the out put current of
the VFD in same workload.
