P23.07
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)

The values of the two function codes are
updated automatically after SM parameter
autotuning is completed.

e frequency is lower than the
current
-loop high-frequency switching threshold
(
P23.14), the current-loop PI parameters are
P23.09
and P23.10; and when the frequency is
higher tha
n the current-loop high-frequency
switching threshold, the current
-loop PI
parameters are
P23.12 and P23.13.
