P23.01
Speed loop
integral time 1
P23.01 . Above switch-over frequency 2
( P23.05 ), the speed loop PI parameters are
P23.03 and P23.04 ; in between them, the PI
parameters are obtained by linear variation
between two groups of parameters, as shown
in the figure 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 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, users should make
adjustment according to different load
characteristics based on the default PI
parameter to fulfill different needs.

Slip
compensation
coefficient of
vector control
(motoring)
Slip compensation coefficient is used to adjust
the slip frequency of vector control to improve
system speed control precision. Users can
effectively control the static error of speed by
adjusting this parameter properly.
