Thank you to all for help.
The advices I got were great help.
It was not easy but there were two separate thing to make it work:
First I did need were resistors between lines because of long cable. this is
something what is described in Rutex manuals.
Second the phasing of pulse lines were wery close to the limit where
direction of rotation is sensed, in clear words I was connecting wrong lines
as A and A- etc...
Rutex at least R9xxH models can use differential encoders directly, maybe if
same development cycle will continue then next year Rutex will support
absolute encoders. ;)
Now I have 5 pc of R991H in use with mitsubishi servos.
