In Yaskawa systems, specifically the , the error code A.910 (often displayed as A910 ) indicates an Overload Warning . This is a minor fault or alarm notifying the operator that the drive is operating near its thermal limit, but has not yet reached the critical trip point. Meaning and Impact
Squeeze the retention tabs on the fan housing, disconnect the plug-and-play power cable, and slide the old fan out.
Automated machinery relies heavily on clean lubrication. Ensure ball screws and linear guides receive grease at specified operational intervals.
Inspect the frequency reference upper limit () and lower limit ( d2-02 ). yaskawa error code a910
Crucially, A.910 is classified as a , meaning it does not immediately trip the drive or force a hard stop. Instead, it serves as a preemptive notice that the system is operating dangerously close to its thermal or mechanical limitations. Ignoring this code will invariably lead to a critical A.710 (Overload: High Load) or A.720 (Overload: Low Load) alarm, which will instantly shut down the servo motor to prevent catastrophic damage. What Does the A910 Warning Code Mean?
Large load inertia combined with rapid acceleration or deceleration rates. Operating the motor beyond its rated output for too long. Recommended Actions Reduce the Load
If the load factor is too high, try optimizing the motion program: In Yaskawa systems, specifically the , the error code A
Sal’s voice crackled one last time. “A910. Just a loose wire.”
Note: In the older V7 or G5 series, similar functionality might be labeled as CF (Current Offset Fault). Always refer to your specific drive’s technical manual.
He connected his laptop to the drive’s USB port, firing up the SigmaWin+ software. He needed to see the trace data. The code A910 meant the motor was drawing excessive current for a prolonged period, or the drive estimated that the thermal capacity of the motor was exceeded. Automated machinery relies heavily on clean lubrication
"That’s the tricky part, Sarah," Elias said, popping the cover off the servo drive cabinet. "A910 isn't just 'I'm carrying too much weight.' It’s 'I'm working too hard to do absolutely nothing.'"
Cycle the control power to the drive. The A910 alarm should now be cleared. Preventative Maintenance Tips
⚠️ If the alarm persists or occurs under load, the drive may trip on a more serious fault (e.g., LF, PF).
