Seidel DIGIFAS 7201 is a digital AC servo drive rated at 0.9 kVA (1.5 A, 3‑phase) designed for brushless synchronous motors with integrated resolvers. Common failure modes in this class include power supply over‑voltage or phase loss, encoder/resolver signal degradation, and internal MOSFET or driver IC overheating due to improper cooling or firmware faults. First‑check diagnostics: verify input voltage, phase balance, and current limits; inspect for visible burn marks or loose connections on the drive board; review any error codes displayed on the drive’s diagnostic interface (e.g., fault 0x01 = overcurrent, 0x02 = encoder loss).[oss-gpt-20b] |
