Yaskawa Error Code A910 Exclusive ((new))

By staying informed and proactive, you can ensure optimal performance and reliability from your Yaskawa equipment.

If your drive uses an option card (e.g., an EtherCAT or DeviceNet card) that shares the same communication bus as the operator port, a conflict in the scan cycle can trigger A910. This is exclusive to drives with firmware versions earlier than 6.0.

Preventive maintenance ensures that minor alarms like A910 do not evolve into catastrophic hardware failures: yaskawa error code a910 exclusive

When A.910 appears, follow this structured diagnostic sequence:

Once the physical cause is resolved or parameters are corrected: By staying informed and proactive, you can ensure

Alarms require a manual “Fault Reset” before operation can resume. Warnings, however, are designed to clear automatically once the underlying cause is resolved, though parameter changes may be necessary in some cases.

Power down the system completely. Use a multimeter to verify termination torque on the power strip terminals. Ensure that shielding practices conform strictly to the Yaskawa Technical Manual Guidance to prevent stray EMI from corrupting encoder tracking feedback lines. 2. Excessive Mechanical Load & Binding Preventive maintenance ensures that minor alarms like A910

Ensure all cables, particularly those for the digital operator and communication modules, are securely mounted.

Although less common, the SERVOPACK itself may be defective. Internal component failures—particularly in the power stage’s phase current circuitry—can cause the drive to report overload conditions even when external wiring and mechanics are sound.

: Turn off the main circuit power. Disconnect the U, V, and W motor leads from the drive. Use a digital multimeter to verify equal phase-to-phase resistance across all three windings, and use a megohmmeter to ensure there is no insulation breakdown leaking to the ground circuit.
