The TDE Macno SC10 is a 10‑A servo drive rated for 3×180–240 VAC, 45–65 Hz, commonly used in small motor control applications such as textile or CNC machinery. Known failure modes for this class include IGBT/IGBT module burnout due to overcurrent or overheating, capacitor degradation on the power supply section, and loss of communication with PLC/HMI when firmware parameters are corrupted. Initial diagnostics should verify that the 3‑phase supply is within spec and that all fuses and circuit breakers are intact; inspect the drive’s IGBT board for visible scorch marks or swollen electrolytics; then check the diagnostic LEDs/serial output for error codes, followed by a continuity test of the motor leads and input signal lines.[oss-gpt-20b]
