Low Control Loop Count - VibEdit

When a level, as entered in the Schedule tab, is not programmed with enough time for three complete control loops, a window appears. This window is designed to warn the user that there aren't enough control loops to make a meaningful update to the drive before proceeding to the next level. If the risk is acceptable and you want to proceed running anyway, use the following steps to bypass the warning. 

Bypassing the Warning

Even with the "Parameter Validation Failed" warning, it's possible to run the test. To do so: 

1. Review the Command/Level/Time values in the Schedule tab to ensure accuracy.
2. Select the Save button or CTRL + S
3. When the window pops-up, select OK to complete the save operation.
4. Open the file in VibRunner or use the "Open in VibRunner" shortcut and run the test.

Repeat the above procedure each time you make a change to bypass the warning.

How is the Control Loop Calculated?

The control loop duration comes from two basic parameters: 

Frequency Resolution: The Frequency Range / Number of Lines = Frequency Resolution. (Locate in Reference Tab.)

Averages per Loop (K): (Locate in Reference Tab -> Advanced >>)

Control Loop = Averages per loop / Frequency Resolution

Example 1 (Averages per loop = 5 / Frequency Resolution = 1)  (5 / 1) = 5 seconds loop time

Example 1 (Averages per loop = 4 / Frequency Resolution = 4) (4 / 4) = 1 seconds loop time

Note: By default, the Cancel button is highlighted, so using the ENTER or ESC key to close the window will select Cancel or Close, respectively. You must click OK to bypass the warning and save the file!
