P23.07
Slip compensation
coefficient of
vector control
(motoring)
Slip compensation coefficient is used to adjust the
slip frequency of vector control to improve system
speed control precision. You can effectively
control the static error of speed by adjusting this
parameter properly.

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. Fit for SVC mode 0 (P00.00=0) and VC mode
(P00.00=3);
3. The value of this function code will be updated
automatically after parameter autotuning of
synchronous motor is done.

Under VC mode (P00.00=3), below current loop
high-frequency switch-over threshold (P23.14),
current loop PI parameters are P23.09 and
P23.10; above current loop high-frequency
switch-over threshold, current loop PI parameters
are P23.12 and P23.13.
