Yaskawa Error Code A910 Jun 2026
In many cases, it points to a failure in the communication between the servomotor's encoder and the SERVOPACK, preventing the drive from determining the motor's position or speed. Common Causes of A910
The A910 alarm is a (not a fatal fault) indicating that the drive’s output torque has fallen below a preset threshold (set by parameters L6-02 and L6-03) for a longer duration than the allowed detection time (L6-04). yaskawa error code a910
| Test | Method | |------|--------| | | Measure resistance between U-V, V-W, W-U at drive terminals. All should be equal (low ohms, usually <2 Ω). | | Ground insulation | Measure resistance from each phase to ground. Should be >1 MΩ (preferably >10 MΩ). | | Check contactor | If an output contactor exists, ensure it closes fully and has clean contacts. | In many cases, it points to a failure
