Yaskawa Error Code — A910 Link ((better))

To isolate and clear the A.910 warning, follow this sequential diagnostic protocol:

System usually remains online but warns of impending thermal shutdown 🔍 Root Causes of the Yaskawa A910 Error

| Symptom | Likely Cause | Recommended Fix | | :--- | :--- | :--- | | | Electrical Noise / Bad Encoder | Check cable shielding; Replace encoder; Check PG card. | | Motor is coasting (spinning) on start | High inertia load / Gravity | Enable Speed Search (b3-02 = 1) or increase b3-01 threshold. | | Error occurs after maintenance | Wiring swapped or Param mismatch | Swap motor leads (U/V/W) OR adjust parameter F1-02 . Verify F1-01 matches new encoder. | | Error occurs during decel only | Regeneration / Load pushing motor | Adjust deceleration time (C1-02) or check braking resistor. | yaskawa error code a910 link

When an registers on the digital operator or host controller, it points to one of five primary system discrepancies:

Ensure the machine is not carrying more than the maximum permitted load. To isolate and clear the A

[ Normal Operation ] │ ▼ [ Continuous High Torque Load ] │ ▼ 💥 [ A.910 Overload Warning Triggered ] <-- You are here! │ ┌──────────────┴──────────────┐ ▼ ▼ [Take Corrective Action] [Ignore and Continue] │ │ ▼ ▼ [System Stabilizes] ❌ [A.710 / A.720 Fault] (Hard System Shutdown)

The A910 warning is triggered based on the internal calculation of the . The drive monitors the output current relative to the motor’s rated current and calculates an "I²t" (thermal) curve. Verify F1-01 matches new encoder

Motor continuous torque exceeds the rated curve or reaches user-set Pn52B parameters

The option card (e.g., SI-EN3 for EtherNet/IP, SI-P3 for Profibus) has vibrated loose. Industrial environments with high-frequency vibration (presses, punch machines, conveyors) can slowly work a card out of its slot.
