Yaskawa Error Code A910 May 2026

In Yaskawa systems, the code A.910 is an Overload Warning. This minor fault or alarm typically indicates that the motor is drawing current near its rated capacity and is on the verge of a critical overload trip (such as A.710 or A.720).

Wiring Issues: Was there a loose contact in the motor or encoder cables? yaskawa error code a910

Wiring Errors: Faulty contact or incorrect wiring between the Servomotor and the SERVOPACK can cause inefficient power delivery. In Yaskawa systems, the code A

Adjust Parameters: Verify and set a suitable overload warning level in parameter Pn52B. Error Code A910: Servo Motor Overheating Excessive physical

1. Improve Environmental Conditions: Keep the drive cabinet clean and dry. Implement a cooling fan with a filter. A910 is sensitive to temperature fluctuations.
2. Surge Protection: Install line reactors or surge suppressors on the input power side to protect the drive from spikes.
3. Regular Maintenance Schedule: Every 6 months, check terminal tightness, clean internal dust, and verify ground connections.
4. Parameter Backup: Always maintain a backup of your drive parameters using a keypad copy unit or Yaskawa DriveWizard software. This allows you to quickly re-initialize without manual re-entry.
5. Monitor Drive Temperature: Use the drive’s built-in temperature monitoring (parameter o4-12 on GA800). Excessive internal heat accelerates current sensor drift.

Error Code A910: Servo Motor Overheating

Excessive physical load on the motor due to friction, a jammed mechanism, or an undersized motor for the application. Wiring Faults:
