text: <s>[INST] PowerFlex 700S user data Summary: How would one set the source of User Data Reals? Drive is a PowerFlex 700S, 20DD022A3NYYANNNA, Series A, FW 2.003. It has a DriveLogix Phase I controller (5720) and some Flex I/O attached. Parameters 1315 thru 1320. According to the manual, each parameter is General purpose parameter available for storage of real data by the operator. I haven't been able to find where these are configured to put information in them. The DriveLogix project has the drive in the I/O tree, and I was able to find the tags in the Controller Tags section that relate to these parameters. It looks like they're being used to pass tension/speed references and feedback from the drive to the controller and current commands from the controller to the drive. I would like to find out how the tension/speed feedback information gets into the user data registers. I have searched through manuals 20D-UM001F-EN-P, 20D-UM002C-EN-P, and PFLEX-RM002C-EN-E. I have attached a zip archive containing the DriveLogix project file and the parameter file (using DriveExecutive) in case they're useful. Any assistance would be greatly appreciated. [/INST] First of all I've to say I'm not an expert of this product. Anyway, I think to have some answers for you... I guess there have been some confusion between parameter names... the tags you've found inside your Logix project (named i.e. Bridle_Roll_1:I.UserDefinedRealData[0] ) are coming from DeviceLogix User Defined Data, and NOT from parameters 1315 thru 1320 as you thought... these are other beasts... and I think they've not been used here... User Defined Data have been configured using Drive Executive, see the screenshot below. You may find reference to the Peer Communication using User Defined Data inside manual 20D-UM002C-EN-P Hope this helps, - fuzzy logic In order to enhance the reputation of the Forum's contributors, please rate the replies you got and remember to close the thread clicking Choose as Best Answer button over the solving answer.
