: Optimize the motion controller profile by lowering the acceleration and deceleration ramps. If production speeds cannot be reduced, verify system metrics through a sizing program like Yaskawa SigmaSelect . You may need to upgrade to a higher-capacity SERVOPACK and motor combination. 5. Ambient Overheating Inside the Electrical Enclosure
When isolating an exclusive A.910 event, system failure typically points to four primary areas: 1. Mechanical Binding and Friction yaskawa error code a910 exclusive
: This parameter can be your most powerful tool for tuning the drive's response to your specific application. A low value (e.g., 1%) makes the drive very sensitive, sounding the A.910 warning early, while a high value (e.g., 100%) makes it less sensitive. : Optimize the motion controller profile by lowering
High-cycle rates, overly aggressive acceleration/deceleration curves, or continuous peak-torque demands that exceed the motor's rated capacity. Incorrect Parameter Thresholds: The overload warning level parameter ( A low value (e
The motor and drive are rated for a specific continuous torque and current. Prolonged operation at or above these ratings—such as running a motor at 110% of its rated torque for longer than the duty cycle allows—will trip the overload warning.

| Error Code | Type | Severity | Meaning | | :--- | :--- | :--- | :--- | | | Warning | Low | A warning that the motor is approaching an overload condition. It is a "pre-alarm." | | A.720 | Alarm | High | An overload alarm for low-load, continuous operation, indicating sustained excessive torque. | | A.710 | Alarm | High | An overload alarm for high-load, instantaneous peak torque, indicating severe torque spikes. |
