Chapter 6 Detailed function description
-106-
By setting the ratio the speed regulator factors and integration time .you can
adjust the speed of dynamic response characteristics of vector control .Increase
the proportional gain .reducing the integtation time can speed up the daynamics
of the corresponding ring .But the proportional gain is too large or too small
intergtation time are easily lead to system oscillation .overshoot is too large .
Proportional gain is too small can easily cause the system to steady-state oscillation .
and the speed of static difference may exist .
PI speed loop parameters and the inertia motor system are closely related .

F3.06 Slip compensation rate of VC
Setting range:50
～
200% Factory setting:100%
The parameter is used to adjust the slip frequency of vector control and improve the
accuracy of speed control .Properly adjust this parameter can effectively restrain the
stativ speed bias .
F3.07 Torque upper-limit setting
Setting range:0.0
～
200.0% Factory setting:150%
Set 100% correspomds to the rated output current of the inverter .
