P03.07
Speed Loop Output Filter
0~8 (corresponding 0~2^8/10ms)
0
○
Speed loop output filter: speed loop output via first-order filter was sent to current controller, by
increasing this filter to decrease the output current ripple, but dynamic response will be slow down.

○
Slip compensation factor is used in adjusting vector control slip frequency, to improve system speed
control precision, properly adjust the parameter, can effectively suppress speed offset.

○
Above current loop PI adjusting parameter is only applied for vector control mode 1.
The two parameters in PI adjustments of the current loop, it directly affect the system’s dynamic
response speed and control precision, in general case, the user does not need to adjust.
