[RASMB] XL-A "waiting for speed" forever

[Alessandro S. Nascimento]

Dear RASMB members,

we are having a problem with our XL-A. I've searched in the list and the
possible solutions I could find did not solve the problem.

Once the experiment is set up, with stabilized temperature and vacuum (0
micron) running at 3000 rpm the instrument status keeps as "waiting for
speed" while the instrument is already stabilized @ 3000 rpm.

We tried to rapidly remove the white jumper and plug it again and also
tried to setup a non-zero velocity with the door open (forcing a drive
diagnostic). Those suggestions appeared in the list in the past. None of
these could restore the sync between the instrument and the software.

Any clues on what could be going on?

I thank in advance,

-Alessandro
