(collector-emitter voltage) monitoring circuit inside the power section detects a short circuit, or if an IGBT gate degrades, the control card locks out pulse generation instantly. 4. Defective Control Module (6SN1118 Series)
DMG DMU 50 with Siemens 810D / Simodrive 611. Problem: Y-axis would run for 20 minutes, then Error 607. Resetting worked, but fault returned. simodrive 611 error 607
First, he checked the power module. The DC bus voltage was perfect—650V, steady as a rock. Not a short circuit. Good. A short would be easy. or if an IGBT gate degrades
He tapped the membrane key. The display stubbornly repeated: . then Error 607. Resetting worked
). They must be completely balanced (typically under a few ohms). Use a Megohmmeter (500V/1000V) to check each phase against the machine ground.
