Yaskawa Error Code A910

If the machine cycle demands rapid acceleration or deceleration sequences without adequate dwell time, the root-mean-square (RMS) current will exceed the continuous duty rating of the motor. 3. Faulty or Incorrect Wiring

The A.910 warning is automatically cleared once the root cause (mechanical jam, loose wire, etc.) is fixed and the load on the motor returns to normal levels. The warning status on the drive's digital operator should disappear. If it does not, follow the drive's standard warning reset procedure:

Check the configuration profile inside the SERVOPACK using SigmaWin+ or the digital operator. yaskawa error code a910

: Ensure the control panel is well-ventilated and that any internal SERVOPACK fans are functioning correctly.

Unlike a fault code (such as "oF" or "oL"), which trips the drive and stops the motor instantly, an "A" prefix designates an . Key Characteristics of Alarm A910: If the machine cycle demands rapid acceleration or

Look for dust bunnies, lint, oil buildup, or foreign objects jamming the blades. Step 2: Mechanical and Electrical Verification

Disconnect the wiring plug. Place the new fan into the plastic housing cassette, ensuring that the airflow direction arrow stamped on the side of the fan points in the correct direction (usually pulling air upward across the heatsink fins and exhausting it out the top). The warning status on the drive's digital operator

The Yaskawa drive continuously monitors the current flowing to the motor. When it detects the load is approaching the overload protection trigger point, it issues the A910 warning. The drive will continue to operate in this warned state for a short period, but if the excessive load persists, the drive will eventually trip, triggering a full A.710 or A.720 alarm to protect the motor and drive from thermal damage.

Yaskawa error code A.910 Overload Warning commonly found in the Sigma-5 and Sigma-7 servo drive series. It acts as a preemptive alert, indicating that the system is approaching a full overload alarm (A.710 or A.720), which would shut down the drive. Core Meaning
