One of my customers has an overwrapping machine with a PowerFlex 40 controlling the infeed conveyor motor. They want to decrease the decel setting (parameter P40) from 0.5 to 0.3. They are able to change it from the keypad on the drive, and it works on the new setting. Once power is cycled though, it returns to the previous 0.5 value.
The drive is on a Devicenet network, so I'm guessing the changed value is getting overwritten? If so, then by what? In the .dnt file, there is no lock symbol present at parameter 40. What does the little 'scales' icon mean?
HERE is a zipped copy of the .dnt file that was shipped with their machine. The drive in question is at address 4.

P.S. I love this 'descriptive' error I get when opening the .dnt file...
I'm guessing it's trying to say that I am missing certain EDS files?
