Yaskawa Error Code A910 |top| -

Look for brief spikes during acceleration or deceleration. If peak torque regularly hits 300%, shorten the acceleration ramps. Step 3: Audit Parameter Configurations

Industrial environments are rarely pristine. Dust, textile lint, airborne grease, oil mist, or metallic shavings can infiltrate the drive housing. Over time, this debris accumulates on the fan blades and around the spindle, physically restricting the fan from spinning or slowing its RPM below the acceptable threshold. Natural Component Wear and Tear

For more technical details, you can consult resources like the Click2Electro Guide or the Yaskawa Sigma-7 Manual.

: Unlike a hard "Fault," an alarm like A.910 may not immediately stop the motor but serves as a warning that a shutdown is imminent if the load is not reduced. Common Causes yaskawa error code a910

The code indicates that the load on the motor has exceeded a specific threshold for a set amount of time. It acts as a preventive "pre-alarm" to help operators intervene before the system halts production. Common Causes

Before changing any software settings, perform a physical check of the machine.

: If the mechanics are fine but the alarm persists during normal operation, the motor capacity may be insufficient for the application. Important Note: A.910 vs. A.810 Look for brief spikes during acceleration or deceleration

Yaskawa’s technical documentation for your specific drive series (Technical Manual TM.V1000.01, for example) contains detailed timing charts and waveform examples for A910 detection. Always keep the latest manual available for your exact drive revision.

The cooling fan on a Yaskawa VFD is monitored by the drive’s control board, usually via a tachometer signal (pulse count) or current draw evaluation. The A910 code triggers when this monitored signal drops outside of standard parameters. This can happen due to several root causes: Mechanical Blockage or Debris

When "A910" appears on the screen, it is technically classified as an alarm . The drive is telling you: "The cooling fan is operating below its designated speed, or it has stopped completely, but the internal temperatures are still within a safe operational limit." During an A910 alarm, the drive will typically continue running your motor, but the digital operator will flash the code as a warning. Dust, textile lint, airborne grease, oil mist, or

If you operate or maintain automated machinery, encountering an interruption can stall production and impact your bottom line. Among industrial motion control systems, Yaskawa AC servo drives—specifically the Sigma-5, Sigma-7, and Sigma-10 series—are industry standards for precision and reliability. However, like any sophisticated electronics, they display specific codes when something goes wrong.

Cooling fans are mechanical devices with bearings. They have a finite operational lifespan, usually rated between 3 to 7 years depending on ambient temperature and runtime. As the bearing grease dries out, friction increases, causing the fan to slow down or seize completely. Faulty Electrical Connections

Spin the fan gently with a manual tool to ensure it rotates freely.

“What’s it say?” crackled the foreman, Sal, over the radio.
