text: <s>[INST] powerflex 755 defaulting option card after brake slip alarm I had an issue yesterday during commissioning where we were testing the brake slip function and it worked and started lowering then stopping then lowering again. after 3 times of lowering and stopping it started to free fall. I manually set the brake and brought it back down and powered down the drive. when turned power back on the parameters for the I/O card were default and i had to invert relay O and set it up to work the brake again. the drive parameters were still fine. The drive firmware is 14.002 and the I/O card is a 2262C-2R with firmware 1.008 I am also controlling the drive over ethernet via compact logix studio 5000 version 30.11 with ADC turned on [/INST] Parameters resetting is not happening after brake slip alarm, it's happening after you cycled power. Because you're using ADC, the PLC is pushing its parameters over to the drive once the drive makes its ethernet presence known to the controller. Verify your i/o card parameter settings in the PLC I/O tree definition. \\n </s>
