text: <s>[INST] PowerFlex 525 Drive Summary: PowerFlex 525 Drive termianl I/O read writeDear All, I am using PowerFlex 525 Drive on board terminals (Input = ContrlInStatus_DigInTBlk2, Output = OptoOut1 level.0). Problem is if there is communication fault then state of Drive input and outs remains the same before communication lost. My question is  I would like to reset the outputs of drive when communication is lost. So, Please guide me how to fulfil my requirement. Thanks Advance. [/INST] https://literature.rockwellautomation.com/idc/groups/literature/documents/um/520-um001_-en-e.pdf I don't understand what you mean by input = and output =. Would you please instead tell us what values you set parameter T062 (for digital input terminal block 2), T069 (for opto ouput 0), and T070 (for opto output 0 level). With that information, we might be able to help. You can look at parameter C125 on page 125; it tells the drive what to do in event of comm loss. If you have set C125 to value 3 (continue last), then the opto output will likely stay in the state it was at comm loss if the output is configured to be a running signal, or a running above X value in the case of using the level parameter. To do what you describe I think you'll need set to something other than value 3. That should cause the opto output to change state. \\n </s>
