, causing it to trigger even during normal (but heavy) operation. 【安川電機】e-メカサイト ✅ Immediate Troubleshooting Steps Monitor Cumulative Load: Check the drive's monitor mode to see the Cumulative Load Ratio
Unlike a hard "Fault" that stops the motor immediately, A.910 is technically a . It serves as a preemptive notification that the current load on the servomotor is exceeding normal operating parameters. If the condition causing the overload is not addressed, the drive will eventually shut down with a hard fault to protect the hardware from permanent damage. Common Causes of the A.910 Warning
If a single phase (U, V, or W) suffers a high-resistance contact point, the remaining phases overcompensate with excess current to fulfill the position loop request, throwing an overload warning.
Increased friction forces the servo motor to draw more torque to move the same distance. yaskawa error code a910 exclusive
The A910 warning indicates that the motor is working too hard. This is usually caused by mechanical, electrical, or parameter-based issues:
Yaskawa SERVOPACKs continuously calculate the thermal profile and torque generation of the connected servomotor. The A.910 code triggers specifically .
Increased friction within the machine mechanism (e.g., worn bearings, damaged gearbox, lack of lubrication, or mechanical jamming). , causing it to trigger even during normal
Yaskawa servo drives differentiate between two types of operational interruptions: alarms and warnings.
An A910 error is rarely an isolated software glitch. It is almost always a physical response to real-world operational stressors across four primary areas: 1. Mechanical Binding and Excessive Loads
If the load is consistently high (near 100% or higher), the application may be undersized, or a mechanical issue is present. 2. Inspect the Mechanical System If the condition causing the overload is not
To help pinpoint the root cause of your specific issue, please share a few additional details:
In diagnostic settings, swapping the suspect drive’s power supply cable with a known-good drive can help isolate whether a wiring issue exists.
