Yaskawa Error Code A910

The drive uses one or three current sensors (depending on phase count). Over time, these sensors can drift due to thermal stress, electrical spikes, or simply age. When the sensor outputs a non-zero signal at zero current, the A910 alarm trips.

: Check for mechanical blockages and verify that the load matches the motor's capacity. You may need to reconsider operating conditions or increase motor size. Wiring and Connectivity Issues yaskawa error code a910

Ensure all encoder and motor power cables are securely connected and follow the Yaskawa Sigma-7 Wiring Diagrams Adjust Operating Cycle: The drive uses one or three current sensors

He knelt down by the cable tray. During the last maintenance cycle, a zip tie had been pulled too tight around the main power cable (the UVW phases). Over months of the robot's repetitive twisting motion, that sharp plastic edge had slowly sawed its way through the insulation. : Check for mechanical blockages and verify that
