Speed filter time
0.1~20.0ms
1.0ms
For the speed feedback filter time constant, the longer the time, the smoother the
speed, but the larger the sampling delay, the smaller the value, the better when the noise
meets the requirements.

Setting of the ASR (speed loop) proportional gain and integral time point: Increasing
the proportional gain can speed up the system's dynamic response, but if the proportional
gain is too large, the system is easy to generate oscillation. Reducing the integral time can
speed up the system's dynamic response, but if the integral is too small, the system
overshoot is large and is easy to generate oscillation. Usually, the proportional gain is
adjusted first to maximize under the premise that the system is not oscillating; then the
integral time is adjusted to make the system have a fast dynamic response and reduce the
system overshoot.
