Yaskawa Error Code A910

Here is the detailed content regarding the .

Verify Hardware

: If wiring and load are correct but the error persists after power cycling, the SERVOPACK unit itself may be faulty and require replacement.

Unlike "Major Faults" that immediately coast the motor to a stop, the A.910 code is a warning. If you continue operation without addressing the cause, the drive will eventually trigger a full overload alarm and stop. Threshold:

1. Broken shaft or coupling (most common on pumps/fans).
2. Broken belt on a conveyor or fan.
3. Loss of prime in a pump (pump running dry).
4. Tool breakage (in spindle applications).
5. Open circuit between the drive and motor (e.g., blown fuse, contactor open, loose wiring).
6. Motor not magnetized (particular to PM motors).
7. Incorrect parameter settings for L6-02 (torque level) or L6-04 (detection time).

Wiring Errors

: Faulty contact or incorrect wiring between the Servomotor and the SERVOPACK can cause inefficient power delivery.
