Code A910 Link | Yaskawa Error
Route encoder cables away from high-voltage cables and VFDs to minimize electromagnetic interference (EMI). 3. Replace the Encoder Cable
In rare cases, the physical communication card seated in the drive may have shifted or failed. Step-by-Step Troubleshooting Guide 1. Inspect Physical Connections yaskawa error code a910 link
Connect your PC to the drive using the Yaskawa SigmaWin+ Software Tool. Check the value of parameter Pn52B (Overload Warning Level). Ensure it matches factory defaults or calculated machine parameters. Look at your real-time effective torque monitors to determine if the drive is operating above 100% capacity continuously. 4. Technical Specifications Across Yaskawa Platforms Yaskawa Series Code Representation Primary Warning Trigger Associated Hard Faults High internal panel temps / Improper starting torque A.710, A.720 Sigma-5 Motor operating continuously above rated torque bounds A.71, A.72 Sigma-7 Parameter mismatch ( Pn52B ) / Mechanical load spikes A.710, A.720 5. Preventative Maintenance and Best Practices Route encoder cables away from high-voltage cables and
Examine the electrical enclosure housing the drive. High ambient temperatures degrade the continuous thermal rating of electronics. Ensure the SERVOPACK cooling fan is operating cleanly and that the absolute internal cabinet air temperature stays below 55°C (131°F).
