Good morning to you all. Recently I am facing the trouble and have become helpless in resolving the problem.. In this regard I need your valuable experience. System description: Two 6RA70 DC Converter are being used for lathe surface grinding machine one for LHS DC Motor and other for RHS DC Motor. Incremental encoder of Hubner make (OG 9D 1024 type) each at DC motor is used for speed feedback. Present problem: LHS drive converter is getting tripped immediately after the start command. Fault code displayed is F042. Jobs done: Incremental encoder and its connections were thoroughly checked and found ok. Incremental encoder for LHR/RHS motor were swapped and the problem isn't solved. CUD card were swapped and the problem isn't solved. New cable (shielded pair cable) was laid between LHS encoder to drive panel. The problem isn't solved.
