Parameters of P03.00–P03.05 fit for vector
control mode only. Below P03.02, speed loop PI
parameter is P03.00 and P03.01; above P03.06,
speed loop PI parameter is P03.03 and P03.04; in
between, PI parameter is obtained by linear
variation between two groups of parameters, as
shown below.
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 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 inertial, users should make adjustment
based on default PI parameter according to
different load characteristics to fulfill different
needs.
