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).
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?
This occurs when the drive’s communication option card (such as a Modbus, EtherCAT, or PROFINET card) loses its connection with the master controller (PLC) or the wider network. Essentially, the drive is still powered on, but it has "lost the signal" from its commander. Common Causes of A910
Note: Always consult the specific technical manual for your Yaskawa model (GA500, GA700, A1000, V1000) as parameter addresses can vary.
If the PLC goes into "Stop" mode or loses power, the drive will trigger A910.
In the world of industrial automation, Yaskawa AC drives (VFDs) are renowned for their reliability. However, even the most robust systems encounter faults. One such event is the , often accompanied by the description "Link Interruption."
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
Turn off all power to the drive and wait for the "Charge" LED to extinguish. Carefully open the drive cover and ensure the communication option card is firmly snapped into its slot. Over time, vibration can sometimes cause these cards to wiggle loose. How to Clear the A910 Alarm
