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.
