Yaskawa Error Code A910 Exclusive 2021 →

Using Yaskawa’s SigmaWin+ software or the digital operator, navigate to the (Overload Warning Level) parameter. Compare the setting against the application’s normal operating current.

This comprehensive guide provides an in-depth look at Yaskawa error code A.910—from its fundamental meaning to advanced troubleshooting techniques. Whether you are a maintenance technician, controls engineer, or plant manager, the following information will help you diagnose, resolve, and prevent this issue. For clarity, note that error codes may appear on your drive’s digital operator as “A.910,” “A910,” or the hexadecimal equivalent .

Yaskawa SERVOPACKs continuously calculate the thermal profile and torque generation of the connected servomotor. The A.910 code triggers specifically .

Two different parameters are activated that cannot coexist. yaskawa error code a910 exclusive

Inspect safety/interlock devices

: The operating conditions (torque or speed) exceed the rated capacity of the servomotor.

Rapid acceleration and deceleration cycles that exceed the motor's duty cycle will trigger this warning. Whether you are a maintenance technician, controls engineer,

Measure continuity across motor power cable lines (U to ground, V to ground, W to ground) using a high-quality insulation multimeter to confirm there are no active micro-shorts.

Use SigmaWin+ to monitor the "Effective Torque Reference." It should ideally stay below 100%. Check Environment

After changing the conflicting parameters in SigmaWin+, you must: the new parameters to the drive. but little to no movement results

Disconnect the motor from the load where possible and rotate the driven mechanism manually. For a ball screw actuator, rotate the screw 2–3 turns in each direction while feeling for irregular resistance or grinding.

The underlying causes behind the A910 warning generally fall into one of four distinct categories: 1. Mechanical Strain and Obstructions

The servo system may be trying to move a load that is physically obstructed. The motor works harder, but little to no movement results, causing a rapid current surge.

Check if panel fans are working or if the heat sink is obstructed.
