Monitor your facility’s incoming voltage during operation. If the line voltage drops below -15% of nominal, the drive will trip.
Jammed machinery or linear guides requiring excessive force.
: Excessive load due to mechanical friction, binding, or a sudden obstruction in the machine.
Several issues can lead to an A.910 error, ranging from mechanical obstructions to improper motor sizing. yaskawa error code a910
According to Yaskawa technical documentation, error code A910 signifies a "Current Offset Fault" or "Current Detection Circuit Problem" (sometimes listed as oPE related in older models, but specifically A910 as a fatal hardware error in newer firmware).
Follow this sequential troubleshooting path to isolate the issue:
(Note: If you are working with a Yaskawa robot controller like the DX100, NX100, or FS100, code 0910 points to a . This article focuses on the common A.910 Overload Warning found on standard AC Servo Drives). Understanding the A.910 Error Code Monitor your facility’s incoming voltage during operation
Disconnect the motor from the load (machine mechanism) and run the motor in a free-run state.
is not a fault to be taken lightly. It indicates that the drive’s ability to measure motor current is compromised. While the fix can range from a simple auto-tune calibration to a full control board replacement, the diagnostic approach is logical and stepwise.
Quick troubleshooting steps (practical, in order): : Excessive load due to mechanical friction, binding,
Zero.
If the A.910 error is frequent and cannot be fixed by mechanical maintenance or parameter adjustments, the motor encoder or the drive itself may be failing. If the issue is a "SERVOPACK fault," the unit may need to be replaced. To narrow this down, could you tell me:
If ignored, will lead to hard faults (High Load) or A.720 (Low Load). Common Fixes
One such common diagnostic message is , which specifically represents an Internal Fan Fault or Heatsink Cooling Fan Warning .
