Ensure the encoder cable is properly shielded and the shield is grounded at the SERVOPACK side, not at the motor side, to prevent ground loops.
If the mechanical load is within spec, check parameter Pn52B to ensure the warning threshold is appropriate for your operation.
For more detailed technical specifications on detection timing, refer to the Yaskawa Sigma-7 Manual . A.910 fault in Yaskawa Sigma 7 servo drive - Click2Electro
: Excessive load on the motor due to mechanical friction, jamming, or binding in the machinery. Incorrect Wiring yaskawa error code a910 link
To resolve an A.910 error and prevent a full system trip, follow these steps:
The A910 warning is triggered based on the internal calculation of the . The drive monitors the output current relative to the motor’s rated current and calculates an "I²t" (thermal) curve.
The distinction is crucial for minimizing downtime: Ensure the encoder cable is properly shielded and
The overload warning level, specifically , is set too low for the current application, causing premature warnings.
The Yaskawa error code Overload Warning . It serves as a precursor to more severe overload alarms like A.710 (High Load) or A.720 (Low Load). If this warning is ignored, the drive will eventually trigger a hard fault and stop the motor. Common Causes Mechanical Stress
This is the most common cause, where physical resistance in the system forces the motor to work too hard. The distinction is crucial for minimizing downtime: The
Inspect the main power cable (U, V, W phases) and the encoder cable linking the SERVOPACK to the motor. Ensure all industrial circular connectors and terminal blocks are tight, free from oxidation, and devoid of moisture. Ensure that shield bonding matches the recommendations in the Yaskawa manual to prevent electrical noise from corrupting encoder feedback data. 3. Analyze the Cumulative Load via Engineering Tools
Understanding and Fixing Yaskawa Error Code A.910: The Ultimate Overload Troubleshooting Guide
If the A910 stays with the original SERVOPACK, the drive itself has an internal fault. 5. Check Parameter Settings
