And... within the attached photo...
The SMAX value changed on its own from 3500 to the 32767 you see in the photo.

SMAX shows the maximum allowable spindle speed.
Depending on the way that it is driven (i.e. belt ratio, gear ratio, top speed limit) the parameter that sets that value is in the 3700-ish range. The issue you are claiming is due to one or more of the parameters being set at a value of 32767
(When the number 0 through 32767 are totaled...they account for 32768 digits. 32768 is 2 to the 15th power, which is 16 places out in a binary "rack")
On older machines 32767 is the maximum understandable data.
...and likely to have been entered incorrectly, or it is a glitch or noise glitch.
