Yaskawa Error Code A910 [work] Jun 2026

Jammed machinery or linear guides requiring excessive force.

Ensure there are no physical obstructions or worn-out bearings causing extra friction.

Demystifying the Yaskawa Error Code A910: Causes, Fixes, and Prevention

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

Before performing any physical diagnostics, and wait at least 5 to 10 minutes for the internal DC bus capacitors to fully discharge. Verify there is zero voltage at the incoming terminals (L1, L2, L3) and the DC terminals (+, -) using a properly rated multimeter. yaskawa error code a910

Verify that the servomotor and encoder cables are correctly wired and that there are no faulty contacts or loose connections.

: Jammed machinery, worn bearings, or excessive friction in the mechanical system.

: Disconnect the motor from the load and check if the machine moves freely. If the warning disappears when the motor is uncoupled, the issue is likely mechanical friction or a jam. Jammed machinery or linear guides requiring excessive force

Examine the encoder cable for signs of damage: cuts, pinching, or tight bends, particularly near moving parts.

He grabbed his infrared thermometer. The SERVOPACK panel was at 48°C—warm, but well below the 55°C limit. Heat wasn't the ghost tonight. Finding the Friction

The cooling fan on a Yaskawa VFD is monitored by the drive’s control board, usually via a tachometer signal (pulse count) or current draw evaluation. The A910 code triggers when this monitored signal drops outside of standard parameters. This can happen due to several root causes: Mechanical Blockage or Debris

Manually uncouple the servo motor shaft from the mechanical load (e.g., disconnect the coupling or timing belt). This is a minor fault or alarm notifying

| Parameter | Name | Typical Setting | | :--- | :--- | :--- | | L6-01 | Torque Detection Selection | 1 = Low torque detection (alarm only / continues running) | | L6-02 | Torque Detection Level | Set as % of drive rated current. Low torque = lower %. | | L6-03 | Torque Detection Time | 0.1 sec - 10.0 sec. Time torque must stay low to trigger. | | L6-04 | Torque Detection Filter | Filter time constant to prevent false trips. |

Pop the OEM Yaskawa replacement fan in, ensuring the airflow arrows point in the correct direction (usually blowing upward out of the drive). Step 4: Reset the Fan Maintenance Counter

The is an Overload Warning generated by Yaskawa SERVOPACKs. It triggers when the servo motor operates near its thermal capacity limit but before a catastrophic fault forces the system offline.

Most Yaskawa models feature a quick-release plastic clip or a pair of screws holding the fan finger guard and assembly in place. Press the tabs to slide the fan housing out.
