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.
