In very rare cases, if the cause is a momentary input power dip, the alarm may self-clear after a few power cycles. However, Yaskawa’s technical manuals explicitly state that A910 is a “fault” not an “alarm” – meaning the drive will not attempt to run. For 95% of field cases, the drive requires repair or replacement.
"Momentary Power Failure" or "Undervoltage during run" The drive detected that the DC bus voltage dropped below the undervoltage detection level while the motor was running.
| 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. |
Yaskawa Error Code A910 is “exclusive” because it points directly to a hardware failure in the drive’s charging path. While software errors can often be tuned out, A910 demands a hardware-level response. If you see this code, plan for drive replacement or send the unit to a Yaskawa-authorized service center. Do not attempt to bypass the pre-charge circuit – doing so can cause explosive capacitor failure.

Yaskawa is a renowned Japanese company that specializes in the production of high-quality industrial robots, servo drives, and other automation equipment. Their products are widely used in various industries, including manufacturing, automotive, and food processing. However, like any complex machinery, Yaskawa equipment can sometimes encounter errors, one of which is the A910 exclusive error code. In this article, we will delve into the details of the Yaskawa error code A910 exclusive, its causes, symptoms, and most importantly, provide solutions to resolve this issue. yaskawa error code a910 exclusive
What is Yaskawa Error Code A910 Exclusive?
The A910 exclusive error code is a specific fault code that appears on Yaskawa servo drives, particularly on the Σ (Sigma) series. This error code indicates a problem with the servo drive's internal memory or the encoder's communication. When the servo drive detects an error, it immediately stops the motor and displays the A910 error code on the drive's display panel. The "exclusive" term refers to the fact that this error code is specific to certain Yaskawa servo drive models.

Based on Yaskawa documentation (specifically for the GA500, GA700, A1000, and V1000 series drives), Error Code A910 indicates an Overload Warning.
Here is the exclusive breakdown of the error, its causes, and the solution steps.
Error A910: "Charge Circuit Fault"
This alarm indicates that the drive’s internal pre-charge circuit has failed to function correctly. In simple terms, when a drive powers up, it must slowly charge its internal DC bus capacitors to prevent a massive inrush of current. The A910 alarm triggers when the drive detects that the DC bus voltage has not risen as expected within a set time frame.
