The Advanced Drive Technologies TM5‑015i‑1P is an industrial motor control unit designed for high‑speed, precision drives in manufacturing and automation applications. Common failure modes for this class of units include power supply degradation (over‑voltage or ripple), overheating of the internal IGBT modules, and firmware corruption due to improper updates; typical symptoms are erratic speed response, error codes 0x01/0x02, or a complete loss of communication with the PLC. First‑check diagnostics should verify that the input voltage is within ±10 % of spec and that the unit’s temperature sensor reads normal; next inspect all I/O connectors for loose contacts or corrosion, and finally review the drive’s diagnostic log for recent fault codes before proceeding to component replacement or firmware reflash.[oss-gpt-20b]
