Electromotive slip
compensation
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:
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)
and closed-loop vector control mode
(P00.00=3).
The values of the two function codes
are updated automatically after SM parameter
autotuning is completed.
