Decoding Yaskawa Error Code A910: The Exclusive Guide to Causes and Fixes
Yaskawa drives and servopacks are the backbone of modern industrial automation. Known for their robustness and precision, they are the silent workhorses of robotics, CNC machining, and conveyor systems. However, even the most reliable hardware encounters faults. Among the many alphanumeric codes that can flash on a Yaskawa digital operator, Error Code A910 stands out as one of the most misunderstood—and critically important—alerts.
Check the machinery driven by the servomotor for physical obstructions, misalignments, or excessive friction. yaskawa error code a910 exclusive
Remember the golden rule of A910: The operator is usually a victim, not the culprit. The drive’s control board, power supply, or interconnects are the true sources 80% of the time. Decoding Yaskawa Error Code A910: The Exclusive Guide
Common Causes of A910
| Cause | Explanation | |-------|-------------| | Failed pre-charge relay | The relay that bypasses the charging resistor is stuck open. | | Blown charging resistor | The resistor that limits inrush current is open-circuited. | | Low input voltage | Severe brownout or missing phase during power-up. | | DC bus short circuit | An IGBT module failure or external short on DC terminals. | | Control board failure | Rare, but the voltage detection circuit can malfunction. | Among the many alphanumeric codes that can flash
2. The "Soft" Stop: Alarm History or Trip State
If the drive has recently experienced a minor fault that was cleared but not fully reset, the drive may remain in a "Trip" state.
Exclusive Technical Cause (Why it's different from A9.80)
While A9.80 is a standard undervoltage (power loss at stop or standby), A910 is exclusive to Run-time undervoltage.
In exclusive technical terms: The drive’s internal watchdog timer did not receive the expected handshake signal from the digital operator within the specified time window. This is not a parameter setting error (like a motor tuning fault). It is a low-level hardware or firmware handshake failure.
