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


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).

The values of the two function codes are
updated automatically after SM parameter
autotuning is completed.
