text: <s>[INST] PowerFlex 750 as CIP drives Summary: Using Powerflex 750 drives as CIP Integrated motion drives Has anyone had any experience using a 755 drive, 20-750-UFB-1 card and a SSI encoder? I cannot get the Logix PLC to configure the drive in a usable way. [/INST] I have! I have! Getting the settings right required several calls to Tech Support. We had some weirdness occur with getting the drive to configure, I think having to do with one person trying to configure the drive on the network while another was upgrading the firmware on a bunch of Armorblock IO modules. Bad combination; the drive could not handle the RS-WHO calls (40,000 per second, or some such nonsense), and would CIP-SYNC fault. Rockwell has since released a firmware upgrade to fix that. There was much confusion too because Rockwell documentation talks about Channel A and B in the Logix5000 IO tree, but X & Y for the UFB card. It DOES work, but you'll have to give more details for me to be of useful help. \\n </s>
