Over time, mechanical components degrade. If your linear guides, ball screws, bearings, or gearboxes lose lubrication or become misaligned, the motor must exert significantly more torque to overcome the physical resistance. This increased demand forces the continuous output current past the rated capacity. 2. Aggressive Motion Profiles
Once you have cleared the error, implement these best practices to avoid seeing "Yaskawa error code A910 link" again:
[ Normal Operation ] │ ▼ [ Continuous High Torque Load ] │ ▼ 💥 [ A.910 Overload Warning Triggered ] <-- You are here! │ ┌──────────────┴──────────────┐ ▼ ▼ [Take Corrective Action] [Ignore and Continue] │ │ ▼ ▼ [System Stabilizes] ❌ [A.710 / A.720 Fault] (Hard System Shutdown) yaskawa error code a910 link
The keyword "LINK" in A.910 LINK refers to the communication architecture that connects the Yaskawa drive to a higher-level controller, usually via fieldbus. While A.910 itself is an , communication-related errors like A.960 (MECHATROLINK communications warning) and bUS (Option Communication Error) often occur simultaneously or through cascading failures. A common pattern is an unstable communication network causing erratic torque commands, leading to a mechanical overload and triggering A.910 . In such cases, you must:
The A910 error is a protective function designed to prevent mechanical damage or "runaway" scenarios. The drive monitors the speed feedback immediately upon the "Run" command or during a stop sequence. Over time, mechanical components degrade
: If the load is naturally high but within safety limits, you can adjust the warning threshold using parameter Pn52B .
Verify that connections between the Servopack's U, V, W terminals and the motor are secure and not creating a ground fault or short-circuit . Step 3: Verify and Adjust Parameters A common pattern is an unstable communication network
Addressing an A.910 warning quickly avoids machine downtime, product damage, and expensive hardware replacement. Understanding the Mechanics of the A.910 Warning
If the A910 error persists after replacing the cables and verifying the encoder is properly connected, the encoder inside the motor or the serial converter module may need professional repair or replacement.
The is fundamentally a communication handshake problem between the drive’s brain and its add-on card. It is rarely a catastrophic failure; more often, it is a loose screw, a dirty contact, or a parameter mismatch.
Inspect the servomotor and encoder wiring for loose contacts or incorrect phases.
