T008: Cannot home, motion OK

Description
Detection Scenarios
A complete physical obstruction exists in a motion
path that precludes repeated attempts to move
beyond a certain point in the range of motion. Servo
control appears normal but a move profile cannot be
completed. Cartridge may have been returned to a
home slot.
1. A specified move in the X-axis cannot complete
but motion control appears normal.
2. A specified move in the Y-axis cannot complete
but motion control appears normal.
3. A specified move in the Θ-axis cannot complete
but motion control appears normal.
1. Operator Intervention that results in foreign
material or an obstructing object in a library
motion path.
2. Picker locking mechanism left engaged in the
library motion path.
3. Certain damaged hardware conditions that
obstruct motion at a particular point along an axis.

v Verify that no obstructions are present in the path
of the Picker.
v Perform "DR028: Motion Obstruction Diagnostic"
on page 11-42.
v If the problem persists, refer to "Diagnosing a
Problem" on page 10-2 for additional diagnostic
procedures.
Robot motion and servo control appear normal but home
sensors do not transition when the robot is moved through
prescribed search distances and times.
1. X home sensor does not transition while homing.
2. Y home sensor does not transition while homing.
3. Θ home sensor does not transition while homing.
4. Z home sensor does not transition while homing.
