Single-Phase, at last! (r2e4)
FINALLY, I got my r2e4 Bridgeport converted to single-phase.
No more of that damned RPC singing over in the corner, no. As it turns out, the R2E4 machine is basically a single-phase machine, anyway, except for the spindle motor (which is definitely 3-phase). The electronics all run off two (single) phases of the incoming power, and there are no references to the phases. All it took to get them converted was to move a couple of leads. To adapt the spindle, I installed a VFD and a relay isolator that would track the F/R signals from the motor relays, and signal the VFD to start/stop/forward/reverse. It cost only $149 and some labor. Now to make metal in the QUIET! G LLoyd |
