Old Simoreg Frequent F28 Trip

erblaha Posts: 37 Rating: (1)	I have a very old Simoreg DC Drive: Part Number A1-106-150-500 that is frequently (once per shift) tripping on a F28 (processor fault). We have replaced both the processor board and the technology board with no affect. Any ideas on what else might be causing the fault? More information: Other recent faults that have since been cleared and ran. F19 (Armature Open) F12 (Instant Over Current) I know this is a really old product but any infomation would help. Thanks, Eric
