Hi Roger, WA1KAT
I have used the KR-400 as a single unit for the azimuth and a KR-500 as a single unit for the elevation since OSCAR-7 and provided a preventional maintenance they worked very well for many years.
I have the manuals on paper and I have modified the control box of both adding relays and the electronics necessary to command it with PC for the automatic traking.
In a separate email I have sent to you the electrical schematic diagrams for the above modifications.
Tanks for the internet address of the manual.

Hello, Sven LA6KJ
The only information I got from the schematic diagrams is that the
azimuth
motor for the G5400B is a KR-400 and it is an old model of azimuth
rotator
used about 25 years ago as a single azimutal unit.
