Ensure the SERVOPACK has adequate ventilation and that the internal cabinet temperature is maintained at safe levels. Reference for Related Alarms A.910 Overload Warning Pre-alarm (Warning) A.710 Instantaneous Overload Critical Alarm A.720 Continuous Overload Critical Alarm
: Ensure the main supply voltage (parameter P0210) is within the drive's rated range and not permanently too high. Active Loads
The hardware may be fine, but the software parameter that sets the safety margin is set too low.
. If the value stays consistently high (near 100% or above), the load is too heavy. Adjust Operation Cycle Decrease the speed or acceleration/deceleration rates. yaskawa error code a910 link
: If the load is consistently high, consider reducing the operation intensity or upgrading to a higher-capacity motor. Check Cooling
Inspect all connections and ensure the encoder is properly grounded.
The operation pattern (acceleration/deceleration) may exceed the motor’s rated capacity. Ensure the SERVOPACK has adequate ventilation and that
This parameter dictates the precise threshold where the A.910 warning activates. It is typically factory-set to 20% to 100% of the rated load. If set too low, the warning will trip prematurely during ordinary cycles.
: Frequently correlates with discrepancies between the executed run command and the literal feedback data from an integrated linear scale.
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 : If the load is consistently high, consider
: Excessive load on the motor due to mechanical friction, jamming, or binding in the machinery. Incorrect Wiring
Several factors can contribute to the A910 link error:
