Yaskawa Error Code A910 Jun 2026
Rarely, a corrupted parameter set (especially after a poor upload/download operation) can misconfigure the current offset auto-calibration routine. This is more common after battery-backed memory failures.
He knelt down by the cable tray. During the last maintenance cycle, a zip tie had been pulled too tight around the main power cable (the UVW phases). Over months of the robot's repetitive twisting motion, that sharp plastic edge had slowly sawed its way through the insulation.
Industrial environments are rarely pristine. Dust, textile lint, airborne grease, oil mist, or metallic shavings can infiltrate the drive housing. Over time, this debris accumulates on the fan blades and around the spindle, physically restricting the fan from spinning or slowing its RPM below the acceptable threshold. Natural Component Wear and Tear
By treating the A910 alarm as a priority preventative maintenance task, you ensure the longevity of your automation system and eliminate unexpected downtime. To help provide more specific advice, please let me know:

In some cases, the problem isn't the load at all, but a "whisper" that didn't make it through. Incorrect wiring faulty contact
“Cycle power,” she said to Sal.
: If the mechanics are sound, consider adjusting the gain or increasing the overload warning level in parameter Pn52B to better suit your operation.
Is the error happening or while the motor is holding position ? Rarely, a corrupted parameter set (especially after a
Sometimes, the drive is configured to look for a fan signal only under certain conditions, or the warning logic needs to be reset. Check your specific Yaskawa manual for these parameters:
Jenna, the senior technician, was sipping burnt coffee in the control room when the alarm panel lit up. Line 3 was down.
Excessive voltage drop in the supply lines can cause A910, even if the utility power is stable.
For robotic applications specifically using the , a similar code (0910) may indicate a CPU Error , typically requiring a controller restart or hardware inspection. During the last maintenance cycle, a zip tie
| Parameter | Name | Typical Setting | | :--- | :--- | :--- | | L6-01 | Torque Detection Selection | 1 = Low torque detection (alarm only / continues running) | | L6-02 | Torque Detection Level | Set as % of drive rated current. Low torque = lower %. | | L6-03 | Torque Detection Time | 0.1 sec - 10.0 sec. Time torque must stay low to trigger. | | L6-04 | Torque Detection Filter | Filter time constant to prevent false trips. |
“Always is,” Jenna replied, finishing her cold coffee. “The drive just has good manners. It tells you it’s sick before it tries to run a marathon.”
If the drive is installed in a dusty, oily, or dirty environment, airborne particles can accumulate on the fan blades or around the heat sink. This buildup increases friction, slows the fan down, and causes the drive's internal sensors to detect a performance drop. Failed or Disconnected Fan Component
Many Yaskawa drives have a hidden or semi-hidden routine to auto-calibrate the current sensors. This is often the only fix without hardware repair.
While error codes vary, A910 appears prominently in the following series:
Unlike a fault code (such as "oF" or "oL"), which trips the drive and stops the motor instantly, an "A" prefix designates an . Key Characteristics of Alarm A910:
