TDE Macno DSC‑06N/BX is a 4.1 A brushless servo drive rated at 240 VAC, designed for compact industrial motion control with status LEDs and terminal screw connections. Common failure modes in this class include overcurrent protection trips from motor coupling faults or phase imbalance, insulation degradation leading to shorted windings, overheating due to inadequate ventilation, and sensor‑less control errors when the motor encoder or feedback loop is disrupted. First‑check diagnostics should verify the input power supply (240 VAC ±10 %) and confirm that the drive’s status LED indicates normal operation; inspect for visible burn marks or corrosion on the PCB and connectors; then review any fault codes displayed on the drive’s interface or communicated via its I/O ports before proceeding to phase current measurements.[oss-gpt-20b]
