A faulty encoder or internal circuit can sometimes trigger false thermal readings. Recommended Actions: Reduce Load: Decrease the cycle rate or the weight the motor is moving. Check Mechanics:
: The drive has detected that the motor is operating near its rated capacity for a sustained period. If the workload isn't reduced, the system will trip a full alarm and shut down. Common Causes Mechanical jams or increased friction in the machine. yaskawa error code a910
“Hit it,” Jenna said.
Always start with the simple things—measure your incoming voltage, tighten all connections, and disable momentary power loss ride-thru as a diagnostic step. Do not repeatedly reset the alarm without investigating; each undervoltage event stresses the drive’s front-end components. A faulty encoder or internal circuit can sometimes
If the error persists, the CPU board may need repair or replacement through the Yaskawa Motoman Support Center Yaskawa Knowledge Center If the workload isn't reduced, the system will
If safe, mechanically decouple the motor from the load. Run the motor alone. If the A910 disappears, the problem is with the load/mechanics. If the warning persists with no load, the problem is electrical: either the motor, the wiring, or the drive parameters.
(e.g., during acceleration, high speed, or just sitting still)
