7. Click Yes to begin tuning the electric cylinder.
Tuning is complete when the Tune Servo dialog
box opens.
8. Click OK to exit Tuning.
The Tune Results dialog box opens.
9. Click OK if you are satisfied with the tuning results; otherwise, continue with
Calculate
and Configure the Loop Gain
.
Calculate and Configure the Loop Gain
Calculate a position loop bandwidth based on the actual measured inertia values from the Tune
Results dialog box.
In this example, the Tune Results dialog box shows a default Position Loop Bandwidth of
45.14153 Hz, and a Load Inertia Ratio of 6.8707952.
1. Calculate the Corrected Position Bandwidth.
Corrected Position Loop Bandwidth = (Initial Position Loop Bandwidth Result/(Initial
Load Inertia Ratio Result +1)
For example, 5.73532 = 45.14153/7.8707952
