PDMX 126 with AM822 drivers and relays.

Thanks mate, that helps a lot.

I'm thinking then, that the PDMX and motion controllers will be always powered, unless turned off at the on/off switch.

I use the K2 relay on the PDMX, set to active if "outputs enabled", to open/close the DC power going through the latching relay setup.

Meaning, I have to turn on the PDMX first, and have the motion controller and PC up and running, then I can momentary reset to power the motor drivers?

I'll add an attachment, but my last 2 attachments have failed to post up for some reason.

Would something like this be ok for the relay http://www.ebay.com/itm/Single-Phase...YAAOSwdI9Y8ERd

Got the new power supply, a few more wires and I can fire up the beast.

I would not power that up, as by the looks of things, the drivers will release lots of smoke!

Do you have a link to the power supply?
By the looks of it, you've wired the drives up to what should be the AC input to the toroid. The two pair of wires will get connected in either parallel or series, depending on if you want 110VAC or 240VAC.
The main DC output I'd say is from the 4 terminal block at the bottom right, with the other two outputs to the left being for lower voltage/current outputs. 5 and 12VDC?

:) yes after a few beers, wiring not such a good idea.

Take 2.

Still awaiting the AC power relay, and the 882 USB to Rj cord. Does anyone know if this is an easy DIY to make up the USB to rJ connection ?

Was thinking of getting the 2 cords, splicing in the middle and connecting.

You need both a USB to serial converter, which is more than just a cable, and requires a driver, and the serial to RJ-11 cable. Here's the pinout for the RJ-11 cable.

I just ordered one from the US Leadshine distributor.

More progress,

Control box almost complete now with off latching e-stop and reset switch

Black is AC power in
White is relay controlled AC power out for Spindle / H20 pump / Chip extractor
Small black is always on DC power for the UC400 controller + feed to the PDMX BoB

Internals....
68V AC->DC converter on the left, with 12VDC supply off that holding a 40A/250AC Solid State relay at the back closed.

5x882's in the middle, ( still awaiting the tuning cable to arrive )

PMDX 126 on the right.

Still to come - install + connect the UC400ETH, secondary E-stop circuit to the E-stop button from PDMX, limit switch wires & stepper motor connectors on case, cooling fan
