Understanding the Yaskawa A.910 Error Code: Causes and Solutions

While "A910" is commonly mistaken for a Yaskawa code, it is actually a frequent alarm on Siemens SINAMICS and Micromaster drives. On these systems, indicates that the Vdc-max controller has been deactivated because the DC-link voltage has exceeded its limits. Troubleshooting the A910 Alarm

). It serves as a preventative alert, triggering before a critical overload alarm (A.710 or A.720) occurs to protect the motor and drive from damage. Key Technical Details

(Vdc controller configuration) is set correctly for your application. Related Yaskawa Fault Codes

Check motor windings

Check for physical obstructions or increased friction in the drive train.

Primary causes:

1. Broken motor cable (phase open or intermittent)
2. Motor winding failure (open phase)
3. Loose terminal connection on drive output or motor terminals
4. Contactor / relay between drive and motor not closing properly
5. Internal drive output component failure (rare, but possible)

Real-World Scenarios: Case Studies of A910

Scenario A: Conveyor System in a Food Plant

Symptom: A910 appears every Monday morning after a weekend washdown. Root Cause: Humidity condensation on the option card pins. Fix: Installed dielectric grease on the card edge and changed the drive location from below the wash zone to a NEMA 4X enclosure.
