Resolver to Encoder Conversion

I'm working on a low-cost retrofit for my Deckel FP4A and I really want to reuse the existing motors, but I'd like to replace the stock Industrial Drives drives with ones that operate on single phase 220VAC, so in order to do that in an affordable way I think I need to use a resolver to SSI converter to get absolute position data from the motors for commutation by the drives. I'm wondering if anyone has gone down this road before and had any insight to add.

Currently I think I want to use the Delta ASDA-A2 drive and a Vega 2796524 Resolver to SSI Converter, has anyone tried this before?

I'm still going through all the datasheets I can find, but based on what I've found so far, I think this should be a workable solution.

Ideally I would be using a drive that can natively handle resolver feedback, but I haven't had any luck finding such a drive for a reasonable price. Any info is greatly appreciated!

How many amps are the motors, and what voltage?  Got a pic of the motor plates?

Because if it was orignally a 400v machine, you'll need a transformer and high(er) voltage drives than the typical 220/240vac 1p/3p offerings unless you want the motors to run at reduced max speed.

There are a number of 'agnostic' servo drives out there that have resolver inputs.  Copley and Advance Motor Controls (AMC) come to mind, and are generally available on the used market.

Another option is to replace the resolvers with encoders.
