Yaskawa Error Code A910 Exclusive [top]

Measure continuity across motor power cable lines (U to ground, V to ground, W to ground) using a high-quality insulation multimeter to confirm there are no active micro-shorts.

Alarms require a manual “Fault Reset” before operation can resume. Warnings, however, are designed to clear automatically once the underlying cause is resolved, though parameter changes may be necessary in some cases. Measure continuity across motor power cable lines (U

), the system's ability to dissipate heat is reduced, leading to premature overload detection. Mechanical Issues Warnings, however, are designed to clear automatically once

If the alarm persists, determine if external hardware is causing the issue: Turn off the main and control power.

| Scenario | Repair Cost | Success Rate | Recommended Action | | :--- | :--- | :--- | :--- | | Ripple on +5V > 100mV | $200 (re-cap) | 90% | Send control board to electronics repair shop. | | Operator works on other drive | $75 (new JVOP) | 100% | Replace digital operator. | | Operator fails on multiple drives | $400+ | 10% | Inspect main power ground; replace bonding jumpers. | | FFC cable wiggling causes error | $15 (cable) | 99% | Replace FFC cable (part # EC0A234...). | | Drive is GA800 with old FW | $0 (update) | 95% | Update firmware to v7.11 or later. |

The overload warning level for the A.910 code is adjustable. By default, the system is configured to sound the warning at 20% of the time required to trigger an overload alarm. However, if this parameter () has been set too low for your specific application, it can lead to nuisance warnings that may cause unnecessary downtime. In rare cases, the warning can indicate a genuine failure within the SERVOPACK unit itself, which would require replacement.
