Uncouple the servo motor shaft from the mechanical load (gearbox, actuator, or pulley assembly). Rotate the mechanical axis by hand.
Based on Yaskawa documentation and field experience, the A910 warning can be triggered by several primary factors:
If the system frequently hits A.910 during normal operation, your software could suggest a motor capacity audit. You can calculate if the current load/operating conditions are within the motor's rated duty cycle. Troubleshooting Steps for Developers yaskawa error code a910 link
The overload warning can stem from various mechanical, electrical, or parameter-driven factors: Mechanical Binding and Friction
To diagnose and clear the A.910 overload warning safely, execute the following technical checks in order: 1. Isolate the Mechanical Load Uncouple the servo motor shaft from the mechanical
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
For a precise solution, note your (e.g., GA800, GA500, U1000, V1000, A1000, J1000) – A910 behavior is nearly identical across modern Yaskawa AC drives, but terminal locations and parameter numbers can vary slightly. You can calculate if the current load/operating conditions
: Intermittent signal drops force the SERVOPACK to compensate with excessive current loops. 3. Aggressive Operating Profiles
