Morbidelli retrofit with Vickers drives and DC servos

We have these Vickers AZE-CC4Q servo drives with little info on them.

I have some pages of manuals but there is not alot of info. What I can see is it has +-10 velocity control and it says tach but the actual DC Servos has incremental encoders. the manual only show one wire per axis out for position. Should I put a board in between the encoder and drive to split the signal, one side go to 7i77 and the other to the drive.

/EDIT Or will this work like single ended encoders back to the 7i77?

I will attach the manual.

Thanks,

I don't know if they were being used in torque mode. I don't know how I could tell. The control has been removed.

I can use either an encoder splitter or try and use the output as single ended encoders with the 7i77.

Dont know yet.

Another option is to change out the drives for 170 volt dc servo drives. the only ones I saw are step and direction though....

These have a tach on th emotir and an encoder. The differential encoders went directly to the control so we are set.

Ordered the Mesa cards from John late last week.

How did you go with your setup and the Mesa Cards? I have a Morbidelli Author 502 which uses these servos. The controller died a couple of years ago and the machine has just been sitting there collecting dust.

Have been looking into the Mesa cards also, however have little to noidea what to do in regards to interfacing from the Mesa card to the servos.

I am attempting a similar retrofit. Have you perhaps got any wiring diagram for the drive and 7i77?

I've got nothing. Would love to see it done though. wiring up to and tuning to servos seems to be the hardest part, has put me off the task a little.
