Hi if you like some pics for inspiration Look at the retrofit i Do right now they Look similar ..

If you have a datasheet of the servo i might be able to help. In my project it was paramount to keep the Old servos ..

Interesting site and some pretty cool projects... my German is a bit rusty though!
Turns out they are HEDS-5500 A06 encoders. 500 PPR is a little low but it should work to get things going assuming they work with the drivers. There seems to be some issues getting HEDS encoders to work with the Gecko products... not sure if thats the case with the Drivers CNC4PC sells.

Yea 500 PPR is very low, I will probably try and find some new ones around 2000 PPR. I noticed one of the optical disks had a little crimp in it so I might have to replace it anyways. My RoboTool was made in 1988. I am looking at the Gecko G320X pretty closely right now and it seems to fit the spec requirements for my system fairly well.
- It has step/dir
- 0-80 Volt VDC (my servos are listed as 65V)
- 0-20A (is this the same amperage rating as my 3.75A Servos? If it is this is way overkill, but at least gives me the option to upgrade the servos later if I want)
- Encoder input seems to work based on what I have read (requires a little work around for the HEDS encoders) But like I said I may just buy new ones in which case I will make sure they work with it
- The big question mark is the power supply, but if that turns out to be the only holdup I will just replace that with something that is compatible. I will try and get a closer look at the PSU tomorrow.
By the way thanks for all your help mactec, sorry if I seem to do the million questions routine! Hopefully having all the answers here will help other people too. I generally only ask a question when I can't find the answer after a couple hours of googling.

If you can Power up the machine, you would be able to test all of the power supplies outputs, that are being used for the Amps/Drives Etc, this would be the best way to be sure of what you have
The motor rated amps @ 3.75, the peak amps will be much higher, will be around 7A to 8A peak for that motor

It really sucks when a thread like this just dies. Alot of good information but never find out what worked and what didn't.
