Yaskawa Error Code A910 Exclusive

Once the physical cause is resolved or parameters are corrected:

Summary Checklist:

  • Acceleration/Deceleration Issues: The accel/decel times (C1-xx parameters) are too short, causing high current spikes during starting/stopping that trigger the thermal calculation.
  • Voltage Issues: Low input voltage causing the motor to draw higher current to maintain power.
  • Motor Overheating: The motor itself is running hot due to ambient temperature or blocked cooling fins, lowering its tolerance for current.

  • DC Bus / Rectifier Issues

    • | Step | Action | Expected Result | | :--- | :--- | :--- | | 1 | Monitor U1-07 (DC Bus Voltage) during normal run. | Should be ~1.35x input voltage (e.g., 540-620VDC for 400V class, 270-310VDC for 200V class). | | 2 | Check L2-05 (Undervoltage detection level). Factory default is usually 380VDC (400V class). If set too high, nuisance A910 occurs. | Lower L2-05 by 5-10% only if power supply is truly unstable. | | 3 | Check L2-01 (Momentary Power Loss Ride-Thru Time). Default = 1.0 sec. | Increase to 2.0 seconds if utility sags are common. | | 4 | Measure input voltage while running at 100% load. | Voltage drop should not exceed 10% from no-load to full-load. | Once the physical cause is resolved or parameters
