Yaskawa Error Code A910 Exclusive [hot]

Physical obstruction or excessive friction in the machine's moving parts.

Increased friction within the machine mechanism (e.g., worn bearings, damaged gearbox, lack of lubrication, or mechanical jamming).

The most common cause is the misuse of parameter settings in the Pnxxx group.

Ensure your control cabinets have clean, functioning air filters and climate control units.

The Yaskawa error code (often displayed as A.910 ) indicates a "Momentary Power Loss" or "Undervoltage during Run" fault on Yaskawa AC drives (e.g., A1000, V1000, J1000, GA500, GA800 series).

| Parameter | Setting | Effect | |-----------|---------|--------| | L2-05 | 0 (default) / 1 / 2 | . 0 = standard; 1 = continue operation with reduced torque; 2 = alarm only (continue running) | | L2-11 | 0.0–2.0 sec | Minimum allowable DC bus voltage during undervoltage – increase slightly if nuisance trips occur | | L2-13 | 0.0–2.0 sec | Power loss ride-through time – longer time allows drive to keep running through brief sags (requires appropriate load) |

Loose or corroded contacts in the main U/V/W motor power cable force the drive to draw imbalanced currents. : You can often find additional details on

Watch for during acceleration and deceleration phases. Step 4: Verify Environmental Conditions

Yaskawa AC drives (inverters) are industry standards for precise motor control and reliability. However, like any complex industrial automation component, they utilize a sophisticated diagnostic system to protect both the drive and the connected machinery. One specific code that operators and maintenance technicians encounter is .

While it doesn't always immediately stop the motor, it serves as a critical pre-emptive alert that the system is approaching a full overload alarm, which will halt production. Understanding the "Exclusive" Nature of A.910 The A.910 code is unique because it is a warning (Gr.2) rather than a hard fault (Gr.1)
