went to zero machine y axis went nuts (sounded like an earthquake)
found the y motor field winding to be burnt. we had the motor rewound.
today we tried to zero machine the y axis would take off full speed
and fault out (following error) swapped two of the Leeds. retried to zero
same thing. found the motor the be hot so we took it apart the winding
(one phase?) might have overheated we ran for maybe 30 seconds any ideas?
