1394 servo drive question

[dave w 0]

Hi all, I have an application using a allen bradley 1394 servo drive connected thru a 1764hsrv card on the plc. I changed the pitch of the ball screw and I don't know what to change in the data files to get this to scale the correct incremental moves. Does anyone know these systems and could give me a hand? Thanks Dave

Dave - It's busy season for me and I'm a neophyte myself with servos, but have you pulled down the 1764-hsrv User Manual from the AB Library and checked it out. Screw Pitch should be a simple one. 1764? is that Flex or Compactlogix? If you're using RSlogix 5000 you probably want to check out the porperties pane of the controller tree and change your feddback parameters.

Found the correct data file to change and had to manipulate the copy line in the logic to get it to work but its working. Thanks for the help and it was a 1746 not a 1764
