text: <s>[INST] 2094-EN02D-M01-50 experiencing GuardInternalFault Summary: Weird Fault Never Seen and Hard to FInd Documentation On I have a 2094-EN02D-M01-50 amplifier which is part of an RSlogix Version 20 / Kinetix Motion System which is faulting intermittently. The LED on the Amplifier scrolls Safe Fault 01 Internal Hardware 12  while the RSLogix 5000 Software when you open properties of the Axis shows Guard Fault ; Guard Internal Fault ; Immediate Stop . A search of the Logix online Help got me to this gem of data “An Internal Fault has been detected by the Safety Core Hardware. This can includes safety processor faults, interprocessor communications faults, safety power supply faults and gate drive circuitry.” .. While that tells me what the problem might be I cannot find a guide or descriptions for how to troubleshoot this further. I am waiting for a call back from my RA Distributor Tech/Drives Guru, but also hoped someone here had an idea?
