Elge AZSE is a DC servo drive module used for precise speed and position control of industrial servo motors, featuring built‑in current sensing, torque adjustment, and serial communication. Known failure modes on this family include power supply over‑voltage or ripple causing the drive to shut down, overheating due to blocked cooling vents or excessive motor load, and firmware corruption that results in error codes such as “0x01” (over‑current) or “0x02” (communication timeout). First‑check diagnostics should verify input voltage integrity with a multimeter, inspect the power supply unit for proper regulation and heat dissipation, and review any logged error codes via the drive’s serial interface. If those checks are clean, perform a visual inspection of PCB traces for burn marks or cracked components, then test the motor feedback loop by disconnecting the motor and applying a known reference signal to confirm driver output.[oss-gpt-20b]
