Press the key on the digital operator or cycle the drive’s power.
The Yaskawa A910 error is almost always a . By systematically checking your cabling, reducing electrical noise, and verifying your PLC status, you can resolve the "Link Interruption" and minimize downtime.
If the communication timeout is too aggressive (e.g., 10ms), try increasing it slightly to allow for normal network latency. 5. Reseat the Option Card yaskawa error code a910 link
This article breaks down what this error means, why it happens, and the step-by-step process to get your machinery back online. What is Yaskawa Error A910?
Start with the basics. Ensure all communication cables are securely seated in their ports. Check for sharp bends or crimps in the cable that might have damaged the internal copper or fiber. 2. Verify the Master Controller Status Press the key on the digital operator or
Ensure that your communication cables are and that the shields are properly grounded. Avoid running communication lines parallel to motor output cables or high-voltage AC lines. If they must cross, they should do so at a 90-degree angle. 4. Review Drive Parameters
In Yaskawa technical manuals, is classified as an Alarm , not necessarily a hard Fault (though it can stop operations). Specifically, it indicates a Station Link Interruption . If the communication timeout is too aggressive (e
Unlike a "Fault" which requires a manual reset, an like A910 often clears itself once the underlying cause is resolved (i.e., when the link is restored). However, if your drive is configured to "Fault on Communication Loss," you may need to: Restore the link.
