Common Fault Codes and Fault Phenomena
ALM01: Overcurrent Fault → Motor insulation short circuit, driver power transistor damage, power line grounding
ALM02: Overvoltage Fault → Grid voltage too high, regenerative resistor damage, motor emergency stop inertia feedback overvoltage
ALM03: Undervoltage → Input power phase missing, wiring loose, main circuit rectifier damage
ALM05: Encoder Abnormality → Encoder wire broken, plug loose, encoder damaged
No Digital Tube Display: Main Circuit Power Input Not Input, Internal Switching Power Supply Board Damaged
