T121: Robotics Y-Axis Motion Failure, No Tape in Picker

Description
Detection Scenario
The robotics firmware auto-level process was unable to update one of the
Robot Controller Board's flash parts.
One of the Robot Controller Board's flash partitions is bad.
Robot Assembly
Perform "DR086: Resolve Robotics Degraded Flash Warning" on page 6-86.
GUI Description: A Y-axis motion error occurred while the robot was moving
a tape cartridge.
Explanation: A y-axis motion error that cannot be considered a complete
obstruction has been reported by robotics. Because a tape is in the picker,
tape recovery must be a part of the resolution strategy. This ticket only
occurs during a robotics move, not during a robotics get or put.
1. A specified move in the y-axis cannot complete.
2. Robotics firmware reports a y-axis error condition.
1. A physical obstruction in the path of the robot's motion. Examples
include tape cartridges that are extending from the picker assembly or
from a storage location, as well as tape cartridges or debris that may
have collected on the floor of the library.
2. A large number of electrical hardware failures. Firmware or hardware
detects that motion control is not occurring properly (encoder issues,
motor driving circuits, motor winding issues, etc.)
3. A relatively small number of mechanical hardware failures that do not
result in the detection of a complete obstruction, but where motion
control generates robotics firmware error codes (contamination or damage
to encoder wheel, high friction, etc.).

GUI Description: A Y-axis motion error occurred, which does not seem to be
the result of robotic obstruction.
Explanation: A y-axis motion error that cannot be considered a complete
obstruction has been reported by robotics. Because a tape is not in the picker,
tape recovery is not necessary as part of the resolution strategy. This ticket
only occurs during a robotics move, not during a robotics get or put.
1. A specified move in the y-axis cannot complete.
2. Robotics firmware reports a y-axis error condition.
