Hi everyone,
Quite a while back I posted in another part of the forum about my find. I'm finally gathering up parts to convert an SM-1 to run with Mach3. At least I think it is a SM-1. The swingout arm says SM-1, the serial number starts with SDX. It is vintage 1984. I'm collecting parts (computer, tooling, VFD for the spindle so I don't need 3 phase power). I'm also seeking some info on the servos...
I have no idea what kind of volts and amperage the servos require. A Servomate drive "cluster" is inside, and says it is 90V. However, I am going to replace that with either Rutex or Geckos. It looks like I will need to build my own supply because there is quite a mess of wires poking out everywhere. The servos have labels that are almost unreadable. The readable part is Model E26-4 (or something like that) . They are Electro Craft servos. Does anyone have any info on these servos (max,normal current and voltage) so that I can calculate what I need to be able to supply to whatever drives I buy?
Also, would a 5HP VFD be enough to power this thing through single phase? I think it is a 3HP motor. The sticker says 8.4A, so hopefully a 15A VFD would be enough deration.
Thanks for any info. I think this will be fun but expensive, even though I'm trying to do it as cheaply as possible!
