Intermittent problem encountered on the production line, most of the time machine stops displaying "CF3" and "oc" (over current) and sometimes GFF (Ground Fault), What Could Possibly Its Defective Com
Dismantled it to resolder the IGBT once CF3 error code has encountered. This resolves the problem but the problem returned back, still CF3 keeps (flashing) and sometimes "oc" and "GFF". Electrically Check the UVW (output) but no anomaly on the resitance and or voltage. Never attempted to adjust anything on its program. Please help. Thanks in advance and More power!!!!
