Name Description Default Modify
by setting the proportional coefficient and integral
time of speed regulator. Increasing proportional
gain or reducing 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.
PI parameters have a close relationship with the
inertia of the system. Adjust PI parameters
depending on different loads to meet various
demands.

coefficient of
vector control
Slip compensation coefficient is used to adjust
the slip frequency of the vector control and
improve the speed control accuracy of the
system. Adjusting the parameter properly can
control the speed steady-state error.

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 closed-loop vector
control mode (P00.00=3)
