7. Select Yes to exit Tuning, and display the Tune Results dialog box.
Calculate and Configure the Loop Gain
You must calculate a position loop bandwidth based on the actual measured
inertia. This is with the values from the Tune Results dialog box for a ball screw
drive linear stage.
The Tune Results dialog box above shows a default Position Loop Bandwidth of
45.14153 Hz, and a Load Inertia Ratio of 6.8707952.
1. Calculate the Corrected Position Bandwidth as follows:
Corrected Position Loop Bandwidth = (Initial Position Loop Bandwidth
Result/(Initial Load Inertia Ratio Result +1)
For example, 5.73532 = 45.14153 / 7.8707952.
IMPORTANT These Loop Gain procedures apply only to ball screw linear stages.
