...Which brings up another question: Do the servo drives (control circuitry, at least) use a single phase? This was my hypothesis and maybe this explains it? I thought the x/y/z servos were still 3...

Update: We haven't run it very much to ensure it's 'fixed' (other priorities), but I switched the 3-phase legs around to see if the higher voltage leg might work better on another phase, and lo and...

I finally have the RPC hooked up to the EMCO 320. Machine functions. EXCEPT it gets both server errors 414 & 424, with the DC over current bit set (0000100). Alarm on the servo amp gives the DC...

Thanks. I also got another good data point where depending on which version of the EMCO is can pull 28/33 amps, 3-phase. That's significant enough to warrant the larger size (e.g. AD20).

Let me clarify my disconnect. Main drive requires 2.6/4.0 kw for 100%/50% duty cycle, or 2.95/4.96 HP. Therefore, assuming the design is for 5HP, The American Rotary says an AD10 is good for 3.7Kw,...

We will be getting in an EMCO 320. However, I only have single-phase and a bit confused as to the sizing of an RPC. The docs that I've seen says it need 10 kva, which is quite a lot.. The spindle...
