Description
in between them, the PI parameters are obtained
by linear variation between two groups of
parameters, as shown in the figure below.
PI parameters
(P23.00,P23.01)
P23.02
The speed loop dynamic response characteristics
of vector control can be adjusted by setting the
proportional coefficient and integral time of speed
regulator. Increase proportional gain or decrease
integral time can accelerate dynamic response of
speed loop, however, if the proportional gain is too
large or integral time is too small, system
oscillation and large overshoot may occur; if
proportional gain is too small, stable oscillation or
speed offset may occur.
Speed loop PI parameter is closely related to the
system inertia, you should make adjustment
according to different load characteristics based
on the default PI parameter to fulfill different
needs.
