Y motor was drawing excessive current compared to SW setting as it traveled to upper exchange position
After thorough troubleshooting reduced the speed of the Y motor (#3 to #2 ) in RAITH.VBD 
wrote a Jscript  snippet to trap errors and conflicts between motor and SW using the debug section of the Virtual motor control module.
Will need to return settings to normal when resolved; likely by replacing the Y motor control motor or coupling.
RAITH field service responded immediately by phone and will be sending out Lev Markov when has returned to bay area shortly.
