: Faulty contacts or incorrect wiring between the servomotor and encoder.
Inspect encoder cable connections for noise-related issues. If the system is in a high-noise environment, ensure the encoder cable is shielded, and that the shield is grounded properly. 3. Review Parameter Settings Pn402cap P sub n 402 (Overload Warning Level): Check if this setting is too low. Pn400cap P sub n 400 Pn401cap P sub n 401
Carefully inspect the connections from the drive to both the servomotor and its encoder. Look for: yaskawa error code a910
If the machine moves frequently, reducing acceleration/deceleration times can lower the peak load. 4. Monitor with SigmaWin+

Isolating the root cause of an A910 warning involves checking three distinct areas: mechanical resistance, electrical/parameter configurations, and environmental factors. 1. Mechanical Binding and Friction Look for: If the machine moves frequently, reducing
: Mechanical problems (e.g., binding, friction) or operating conditions that exceed the motor's capacity.
Unlike a hard "Fault," the A.910 is classified as a . This means the motor will generally continue to run, but the drive’s digital operator will flash the code to indicate that the operation has exceeded the overload protection characteristics. Primary Causes and Remedies Potential Cause Recommended Remedy Mechanical Obstruction
The is an Overload Warning issued by Yaskawa SERVOPACKs (including the Sigma-3 , Sigma-5 , and Sigma-7 series). It acts as a preventative alert, signaling that the motor is running close to its thermal or mechanical limits and will soon trip into a hard Overload Fault (A.710 or A.720) if operation continues unchanged.
