text: <s>[INST] Powerflex 70 EC Change Parameter 80 via Devicenet? Summary: Is it possible to Change Parameter 80 open loop to encoder via devicenet? I am trying to change parameter 80 feedback select to select open loop if the encoder failed. Im attempting to do this over a datalink. My data link is working however I cannot change the feed back type. I need this for a backup. [/INST] If you're sure the datalink is working fine (i.e. if writing to another parameter works), then it is probably due to some conditions needed in order to have this parameter changed (other related parameters, status of the drive...) try first to do the same operation through an HIM, and see if it works; then try the procedure in the same way through the Devicenet. - fuzzy logic \\n </s>
