The resolver information for Dynomotion can be found at https://dynomotion.com/Help/Resolver/Resolver.htm
That example uses their old obsolete KMotion board, but the same can still be done using a KFlop + Kanalog.
If you did want to give it a try, I do have a spare KFlop + Kanalog board you could borrow.

I did do a quick bit googling, and this is the only active product I've found so far - http://addi-data.com/products/resolv...tal-converter/

RS do have an entire section of Resolver to Digital chips, but even the bare chips have some interesting price tags, so I'd imagine that converter will be at least a couple hundred euros, if not a lot more!

Thanks, Moray, to be honest, I think the Resolvers are going to get the bullet or like you mentioned earlier the 4th motor will get swapped out. They are just complicating the job too much and for no gain really. Replacement encoders are easily found and not expensive so for the price of a Resolver card they can be replaced and keep job simple.

Ok I'm seriously considering something along these lines. That's a lot of firepower for £2k with Absolute encoder motors/drives and all cables etc. I've also been in touch with someone who's been retrofitting machines using these particular manufacturers controllers for 2yrs and they say good things about them. So I'm not worried about the company or quality. They say it's not quite Siemans quality but does the job fine and reasonable to set up with good support.
I'm waiting for them to come back to me with prices because I want an extra panel for MPG etc and a slightly larger motor size. I also requested manuals.

I'm also looking at Adtech controller with 10" screen with there Q series Drives/Motors which again if bought from China will come for around £2k mark. Not Absolute encoders but still decent quality.

It will probably mean I've got to change the motor on the 4th axis or find a DC brushed drive like Argon that will accept Step & Dir inputs but can live with that. Or as mentioned I'll just sell it on.?

The search still goes on, no stone will be left unturned or unconsidered.!
