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.

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. You can effectively control
the static error of speed by adjusting this
parameter properly.

Note:
1. These two parameters are used to adjust PI
parameters of current loop; it affects dynamic
response speed and control precision of the
system directly. The default value needs no
adjustment under common conditions;
2. Applicable to SVC mode 0 (P00.00=0), SVC
mode 1 (P00.00=1), and FVC (P00.00=3)
