High ambient temperatures (exceeding 40–55°C) within the control panel can reduce the drive's thermal overhead. Troubleshooting & Solutions Yaskawa Servo Drive Alarm Codes Guide | PDF - Scribd
For Sigma-7 series drives, A.910 corresponds to hex warning code .
Several factors can trigger the A910 error code. Some of the most common causes include:
I can provide tailored parameter settings or electrical testing steps based on your setup. Share public link yaskawa error code a910 exclusive
When A.910 appears, follow this structured diagnostic sequence:
If the alarm persists, determine if external hardware is causing the issue: Turn off the main and control power.
Reduce acceleration rates, extend cycle dwell times, or upgrade to a larger motor. Proactive Strategies to Prevent Overload Warnings Some of the most common causes include: I
To resolve the A910 error code, follow these troubleshooting steps:
Access the drive parameters to check the software version (Parameter or U1-25 depending on the model). Cross-reference this with Yaskawa’s technical support documentation to ensure your control board and option cards are running compatible, stable firmware releases. Long-Term Prevention Strategies
Turn off power and uncouple the motor shaft from the gearbox or linear mechanism. Proactive Strategies to Prevent Overload Warnings To resolve
Power the system back up and execute a low-RPM manual test using the SigmaWin+ diagnostic software tool .
If load has increased permanently, you may need to upsize the motor or servo system. Where possible, reduce the commanded acceleration or deceleration rates to lower peak torque demands.
In diagnostic settings, swapping the suspect drive’s power supply cable with a known-good drive can help isolate whether a wiring issue exists.
