Yaskawa Error Code A910 Link
Check motor cable
Check motor windings
Check for external contactor
Temporarily disable detection (for test only)
Test drive with a known good motor
If the hardware is secure, check these key drive parameters (displayed as o1-xx, F6-xx, H5-xx depending on your drive series):
| Parameter | Value | Purpose | | :--- | :--- | :--- | | o1-03 (or F6-03) | 0 (Default) | Disables "Option Card Detection Stop" during run. | | H5-01 | 1 - 3 (Network dependent) | Sets communication protocol. "0" will throw A910. | | F6-01 (A1000) | 1 (Enabled) | Option Card power enable. | yaskawa error code a910 link
Note: If parameters were erased due to a battery failure, the drive may default to "No Option Installed" even though one is physically present.
In less than 5% of cases, the drive’s main control board is defective. The socket for the option card may have cracked solder joints or a dead communication controller. Check motor cable
If A910 appears intermittently or frequently, the following actions are recommended:
| Scenario | Recommended Action |
| :--- | :--- |
| Parameter Error | Perform an Autotune (Tune the motor parameters). This ensures the drive knows the exact electrical characteristics of the motor. |
| Genuine Overload | 1. Reduce the mechanical load.
2. Increase acceleration time (C1-01, etc.) to reduce current spikes during start.
3. Consider replacing the motor with a larger frame size. |
| Cyclic Loads | If the load pulses (e.g., a press machine), the RMS current might be fine, but the peak current triggers the alarm. Adjust the L3-03 (Overload Limit Level). |
| Warning Annoyance | If the operator is aware of the load and wishes to ignore the warning (not recommended), parameter L3-01 can be changed from "Enabled" to "Disabled" (Value 0), provided external thermal protection exists. | Check motor windings
