Description
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.

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.
Setting range: 50–200%
The two function codes impact the dynamic
response speed and control accuracy of the
system. Generally, you do not need to modify
the two function codes.
Applicable to SVC mode 0 (P00.00=0), SVC
mode 1 (P00.00=1), and closed-loop vector
control mode (P00.00=3).
Setting range: 0–65535
