The Advanced Drive Technology TM5‑015i‑1P 48691‑107D is an IFT Drive Cube, a high‑performance three‑phase variable frequency drive used to control induction motors in industrial machinery. Common failure points for this class of drives include overheating or burnout of the power MOSFETs and gate drivers, degradation of the input/output protection circuitry, and failure of the internal microcontroller due to firmware corruption or thermal cycling. Initial troubleshooting should verify that the supply voltage is within spec and free of ripple, inspect all I/O connections and protective relays for continuity and proper operation, and review any stored error codes on the drive’s diagnostic display for clues such as “DC bus overvoltage” or “MOSFET failure.”[oss-gpt-20b]
