Re: Newport XPS and Motor record

[John Hammonds <JPHammonds@anl.gov>]

I once had a problem that the configured velocity (in the motor record) 
was not allowed by the XPS.  It returned the same error code.  This was 
a manually configured motor.   We had to play around a bit to get the 
XPS configuration correct.
