Figure 216: Velocity Loop Step Response Velocity Feedback vs. Time Kp=4000 Ki=30
VLGN = 32
The response shown above has a rather large overshoot, however there are no adverse
effect beyond the initial overshoot and oscillation. The overshoot indicates that the user
may wish to reduce the Velocity Loop Gain.
Figure 217: Velocity Loop Step Response Velocity Feedback vs. Time Kp=4000 Ki=30
VLGN = 48
The response shown above exhibits an overshoot and notable ringing in the response. This
response is starting to indicate that the velocity loop gain is greater than necessary.
