: Use the drive’s monitoring functions to check the effective torque reference . If the average torque is consistently above 100%, you may need to reduce the load or the duty cycle.
: Ensure panel fans are operational and the temperature is within the specified range ( 55∘C55 raised to the composed with power C yaskawa error code a910
Excessive friction or a physical obstruction in the machinery. : Use the drive’s monitoring functions to check
: Unlike a hard "Fault," an alarm like A.910 may not immediately stop the motor but serves as a warning that a shutdown is imminent if the load is not reduced. Common Causes : Unlike a hard "Fault," an alarm like A
: In rare cases, a failing SERVOPACK or motor internal encoder can trigger false or premature overload warnings. Troubleshooting and Remedies
: The motor is physically struggling with a load that exceeds its rated torque, or there is mechanical friction (e.g., worn bearings, misalignment).
in the power or encoder cables can cause erratic readings. The drive misinterprets these signals as a struggle to move, triggering the warning even if the mechanics are perfectly smooth. How the Story Ends (Troubleshooting)
