Common faults of Alpha servo drives include: power-on without display, with display without output, overcurrent, overvoltage, undervoltage, overheating, overload, overspeed, phase loss, jitter, encoder abnormality, module damage, ground fault, parameters Errors etc.

  1. Servo drive is normal without load and abnormal under heavy load.
  2. Whether the servo drive is abnormal at full load and high speed.
  3. Whether the servo drive is normal at full load and low speed.
  4. Whether the servo drive starts and accelerates normally.
  5. Whether the servo drive starts deceleration is normal.
  6. Whether the output voltage of the servo drive is balanced.
  7. Whether the output current of the servo drive is balanced.
  8. When the load of the servo drive changes, whether the current is normal.
