Speed loop Gain 1
Sn211
Speed loop gain has a direct effect on the frequency
response bandwidth of the Speed-control loop.
Without causing vibration or noise Speed-loop-gain can be
increased to obtain a faster speed response.
If Cn025 (load Inertia ratio) is set correctly, the
speed-loop-bandwidth will equal to speed-loop-gain.

Speed-loop Integral time 1
Sn212
Speed loop integral element can eliminate the steady
speed error
and react to even slight speed variations.
Decreasing Integral time can improve system rigidity.
The formula below shows the relationship between Integral
time and Speed loop Gain.
