A Siemens D5000 x-ray powder diffractometer is heavily exploited in my
lab. From time to time the detector (drive) goes dead, stopping moving and
responding (it normally uses theta/2theta mode). After doing the power
down and up, the detector (drive) will come to lifes again and everything
will work fine, until next coma. Recently the problem shows up so frequently
that the detector (drive) goes dead as long as the diffractometer idles
too long (more than half a day, to my estimate).

I couldn't find a ready and economical solution from the Siemens. So
suggestions and advice from any experienced diffractometer users (I
guess most Rieveld users are among them) will be highly appreciated.

Seasonal Greetings!
