T142 - Robotics Y-Axis Hardware Failure
Description GUI Description: The robotic Y-axis gear failed to perform proper motion.
Explanation: Movement of the robot assembly along the Y-axis is
accomplished using the Y-carriage assembly, which contains the Y-motor. The
Y-motor has a gear that is attached directly to the motor shaft. Failure or
degradation of this Y-motor gear is the failure mode for this RAS ticket.
Detection Scenarios Robotics firmware reports a specific hardware error, identifying the Y-carriage
assembly or Y-motor hardware as the source.
Root Causes Failure or degradation of the Y-motor gear that drives the robot assembly
along the y-axis.
