BUSINESS IMPACT
-----------------------
The issue has the following business impact:
Due to this issue, users cannot use the library properly for move operations across rail 2 / 25% of the library moves.

Cause

The handbot servo motor might try to compensate for missed service intervals while moving along the track. This could be due to a problem with track alignment or may indicate a very busy controller that is not able to service the interrupt signals from the motors within the allotted time. The controller may send an error message regarding a low voltage condition that may not necessarily indicate a power issue per se but more of a power surge to compensate for a stalling robot.
-- Error 5051 means "A low voltage condition has been detected on the servo motor power"

Solution

Removed and replaced handbot due to reach amp errors.
