5) Check the appropriate box and enter the Go/no-Go tolerances (in g force) for the x, y, and z axes. Check the
root mean square box, if you want MultiView to graph an average vibration trace for all three axes.
In our example, our previous experience with this particular brand of robot tells us that the bearings are about to
fail, if the vibration exceeds ± 0.4g, and that ± 0.20 is normal. Hence we set ± 0.40 g for
horizontal back-and-forth
movements (the y axis — the key point here), as these are the bearings we believe are about to fail in the end-
effector.
6)
In our example, we ran the AMS through our system, and observed the following traces in the Vibration
screen. (The bearings are clearly about to fail.)
