He grabbed his infrared thermometer. The SERVOPACK panel was at 48°C—warm, but well below the 55°C limit. Heat wasn't the ghost tonight. Finding the Friction
Low Torque Detection (Pre-alarm / Warning)
Specifically, it means the inverter’s internal thermal overload protection logic has calculated that the motor or the inverter itself is being stressed. If the current level remains high, it will eventually trigger a critical fault (usually or A920 ) and shut down the drive to prevent damage.
The A.910 warning is triggered when the drive detects that the torque or current being drawn by the motor has exceeded safe continuous operating levels for an extended period.
He didn't even have to reset the drive; because A.910 is a warning, it cleared itself once the operating conditions returned to normal. The conveyor sped back up, the "Ghost" was gone, and the factory floor returned to its steady, industrial hum. Technical Summary of A.910 🛠️ Overload Warning Severity yaskawa error code a910

A very specific question!
: Incorrect or loose wiring in the servomotor or encoder cables can cause faulty feedback, making the drive "think" it is overloading.
: High temperatures inside the SERVOPACK panel (exceeding ) can reduce performance and trigger warnings. Troubleshooting & Solutions To resolve an A.910 warning, follow these diagnostic steps: He grabbed his infrared thermometer
The is an Overload Warning that indicates a servo drive is nearing its maximum capacity but has not yet reached a critical shutdown state . It serves as a precursor to more severe overload alarms, specifically A.710 (instantaneous maximum load) or A.720 (continuous maximum load). What Does A.910 Mean?
If the error occurs during tuning, check the target value you set for the test run.
This parameter often controls the position error pulse overflow; if set too tight, it can mimic overload behavior.
In many modern Yaskawa drives (like the GA700 or A1000), you need to look for parameter . Finding the Friction Low Torque Detection (Pre-alarm /
Sometimes, the drive is configured to look for a fan signal only under certain conditions, or the warning logic needs to be reset. Check your specific Yaskawa manual for these parameters:
“What’s it say?” crackled the foreman, Sal, over the radio.
Pop the OEM Yaskawa replacement fan in, ensuring the airflow arrows point in the correct direction (usually blowing upward out of the drive). Step 4: Reset the Fan Maintenance Counter
Ensure your drive controller firmware is up to date, as newer firmware versions often optimize parameter validation rules.
