: Increased friction in the machine’s mechanical parts (bearings, slides, or gears) is forcing the motor to work harder.

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).

The A910 code is a warning with the official name Its primary function is to alert the user before a more severe overload alarm, specifically A.710 (High-Load Overload Alarm) or A.720 (Low-Load Overload Alarm), is triggered.

The Yaskawa error code is not a fatal "fault" that stops the machine immediately, but a Warning for Overload . It is essentially the drive’s way of saying, "I am working too hard, and if this continues, I will shut down to protect myself."
