The TDE Macno SC‑06 is a compact industrial servo drive rated at 4 A and 240 VAC, typically used to control AC motors in packaging or CNC applications. Common failure modes for this model include IGBT module burnout (often due to overcurrent or poor heat sinking), power supply board faults (capacitor degradation or transformer winding damage), and firmware corruption that can lock the drive into a fault state. First‑check diagnostics should begin with verifying input voltage and ground integrity, inspecting the IGBT and associated heat sink for signs of overheating or physical damage, and reviewing the drive’s diagnostic LEDs or error code display for specific fault flags before proceeding to board-level inspection.[oss-gpt-20b]
