[AG-TECH] Juddering in Sony PTZ cameras

We have several Sony EVI-D100 PTZ cameras used for AG etc.
(successor to D30 as used in Polycom H323 appliances etc.)
The cameras have AFAIK a stepping motor to control pan/tilt. It is
normally extremely quiet.
At least 2 of them occasionally go into a mode where they start vibrating
in one axis. They usually recover, but not always. It sometimes starts
as a result of a programmed move from one preset to another, but
today also during a manual pan. It is quite noisy and annoying during a
meeting. I thought we had one lemon which was on a secondary camera.
Today we have an AG meeting where I am driving 3 cameras and 2 of them
Has anyone else ever seen this or know what is causing it ?
