Hardinge Lathe CNC Retrofit/Conversion

Ecogoo 240V/1Ph to 380V/3Ph inverter? Available on Aliexpress. No, I don't have one but various people in the forum have used them.

Mate of mine is refitting a mill with an SZGH controller (with a bit of assistance from me) and I suspect I'm going to be writing a macro or two for things like tool-height setting and probing. I don't remember seeing anything about macro programming in the manuals we have - is there a specific manual on this?

Ive got 2 of them. I can try but I'm not sure if that would power the spindle System without causing issues. Keep in mind that the power from the Ecogoo 9000 and 9100 is higher voltage (chopped) to make 380V.

I think you will need a rotary to power the spindle drive.

There is a macro manual, also a PLC one and also a PLC programme which is handy for looking at the ladder but I found it easier to alter the ladder on the control.

I see some PLC info in the one manual but it doesnt show how to create or similar for Tool Change. Anything you can share please Hood?

I'm currently running my complete lathe via a 7.5kw boost inverter, albeit still with the motor from my old rotary phase converter running to provide some base load, and a sine wave filter to ensure no transients make it to the lathe.

So something like the Ecogoo 7.5KW directly into a lathe? What lathe?

This lathe - http://www.mycncuk.com/threads/13970-New-CNC-lathe-day

My current set up is-
7.5KW Boost VF -> sine wave filter -> idler motor (the setup may work fine without it, but it does provide a bit surge/buffer capacity) -> 3ph distribution.
For sine wave filters - https://www.controlpanelproducts.co....o-1200A-CNW933

Due to the workshop being fed via a quite sensitive RCD, I do also have a 7.5KVA isolating transformer feeding the VFD, but you shouldn't need that.

With that setup, the lathe runs fine, although it does dim the lights if I reverse the spindle...
