The LUST AEB060.3‑1 is an AC servo power module that supplies and regulates current for industrial AC servo motors, typically integrated into a larger Lust drive or controller system. Common failure modes include internal regulator faults manifested by short‑to‑ground indicators (e.g., LED 6), overheating of the power MOSFET array, and loss of phase‑shift control due to damaged I/O circuitry. Begin troubleshooting by verifying that the input supply voltage is within spec and that all connectors are secure; then inspect for visible burn marks or swollen capacitors on the board. Check the module’s diagnostic LEDs and any error codes reported by the host controller, and perform a continuity test across the motor output terminals to rule out short circuits. If faults persist, isolate the regulator section for replacement or send the unit to LUST DriveTronics after‑sales service.[oss-gpt-20b]
