Confirm that grounding is properly installed to prevent electrical noise interference. Adjust Parameters Review parameter
: Ensure there are no jams, binding, or excessive friction in your machine.
: Faulty wiring or electromagnetic interference (EMI) on the encoder feedback line introduces tracking jitter, prompting erratic torque spikes.
When troubleshooting, check the "Link" LED's behavior. An active link light accompanying an A.910 warning is strong evidence your network is healthy, and your problem lies in the motor's mechanical or electrical path. yaskawa error code a910 link
Check the communication settings in the drive (typically in the or H5-XX parameter groups depending on your specific model, like the GA700 or A1000).
The A910 alarm is specifically defined as a or "Serial Converter Unit Connection Error."
As noted at the beginning, the "A910 link" search query is a common confusion stemming from the drive's "Link" status LED. It is essential to distinguish the A.910 overload warning from genuine communication errors, which have different codes and causes. Confirm that grounding is properly installed to prevent
If the machine is mechanically clear but still errors out, the performance expectations may exceed the physical limits of the system.
: If the load is consistently high, consider reducing the operation intensity or upgrading to a higher-capacity motor. Check Cooling
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? When troubleshooting, check the "Link" LED's behavior
The most common cause of an overload warning is a physical restriction in the automated machinery.
If you are seeing this error during development or commissioning, check the following:
Note: If parameters were erased due to a battery failure, the drive may default to "No Option Installed" even though one is physically present.
