Yaskawa Error Code A910 Link -
| Parameter | Setting | Effect | |-----------|---------|--------| | L8-07 | 0 | Disables output phase loss detection (not recommended) | | L8-07 | 1 | Enables detection (default) | | L8-07 | 2 | Enables detection with faster response |
| Symptom | Likely Cause | Recommended Fix | | :--- | :--- | :--- | | Motor is stationary, error occurs on Run | 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
Even if the card is seated correctly, dust, humidity, or corrosive gases (like sulfur in paper mills) can oxidize the gold-plated pins on the option card or the socket on the drive control board. | Symptom | Likely Cause | Recommended Fix
Older firmware versions had a bug where A910 would appear after a power cycle if the option card was running the latest firmware. Connect Yaskawa’s DriveWizard software and check for updates. Go to Drive → Maintenance → Firmware Update. Even if the card is seated correctly, dust,
To resolve A910, you must understand these specific Yaskawa parameters:
