You don’t need a fancy VFD, you just need one that a half way decent stepped SIN wave. As long as there are no digital electronics or transformers in the machine you should be fine. If there are digital electronics a true sign wave vfd or rpc is you best bet.

How are the speed of the feed and belt speed controlled? and any other motors in it? You may need to do some rewiring to have a vfd control each function. I don’t think running a vfd from another vfd is a good practice (just a guess).

Is the machine meant to run on 50Hz and/or 60Hz? if so a VFD is an option.
