Make the motor follow.
Tune the controller. Watch motion and signals answer together.
Find the feedback loop
Where does the motor speed go after you change the target?
Did the result match your prediction?
Choose a measurable prediction before changing a setting. Record the current result, change one condition, then check. This compares complete recordings, not the replay cursor.
Waiting for a complete, valid result. A stopped run or unavailable metric cannot be judged; choose another measure if needed.
Prediction and baseline stay in memory for this page only. Use Start a new prediction to choose a new baseline.Close the feedback loop
Measured speed returns to the controller. Pin this run, then switch to open loop with the same target, motor and load events.
Step response
Pin a run, change one setting, then compare the traces.

Read field notesChoose a prediction above before comparing the result.
Use the response plot and the live target, actual speed and error readouts on one replay clock.
Move the target, then replay the response.
The large number is the gain; the smaller number is that term’s output at the replay cursor. Change one gain, then pin and compare the run.
