text: <s>[INST] 1394C-SJT22-D sercos phase 3 ring fault I just installed a reconditioned 1394C-SJT22-D module and the sercos will not get past phase 3. The previous module was working when it was removed. I have double checked the baud rate switches. [/INST] Hi, just found an internal note explaining this as a possible mechanical assembly issue, reguarding the 1394 terminator not seated in the right position... in case I don't know if you can check for this or need to send it again to repair... :smileysad: Another possibility could be the firmware revision of the controller doesn't *match* revision of motion module; in case post again your revisions of Controller, Motion module and 1394C. - fuzzy logic \\n </s>
