These are the 2’nd PI tuning parameter for close loop control.
【NOTE】If Pr.163 set too large, the response will be low, and the system will be unstable.
Pr.161 should keep larger then Pr.162.

1. When speed start from 0rpm to 300rpm (under the 1’st gain switch point), the driver
uses the 1’st PI tuning parameters for close loop control.
2. When speed is in the range of 300 ~ 1500rpm, the driver will change the PI tuning
parameters’ value from 1’st to 2’nd by linear manner.
3. When speed exceeds 1500rpm, the driver uses 2’nd PI tuning parameters for close loop
control.
