MTS Acumen - Manual (Page 169)

Tip:
For experts only: To access the expert level of manual adjustment of tuning parameters, right-click
the Tune for Specimen element on the Explorer panel. This shows the Tuning panel with individual
P Gain, I Gain, D Gain, F Gain, F2 Gain, and FL Filter controls.
Considerations for Tuning
Note:
If you adjust tuning parameters without using or saving the tuning set (by clicking Apply or Done),
a window will open to give you the option of reverting to original values. If you choose to revert,
actuator power will be removed to maintain stability.
Note:
Stiffness, mass, and damping are characteristics that apply to the entire system, not just the specimen.
Recommended :
It is best practice to tune using a dummy specimen that has similar characteristics (mass,
stiffness, and damping) to the specimen you intend to test. Set appropriate fixture and specimen
limits, turn them on, and set the action to C-Stop Interlock.
MTS recommends setting the Action to C-Stop Interlock in all cases. Before setting the
action to something other than C-Stop Interlock, contact an MTS service representative.
The Tune for Specimen Element
The Tune for Specimen element allows you to obtain tuning values by selecting and using existing tuning
sets as is, manually adjusting the values of existing tuning sets (using basic, advanced, and expert level
controls), or by having the system automatically determine initial tuning values for you, which you may use
as is or adjust manually.
