Control panel wire gauge question?

[JAZZCNC]

I have bumped this up so that Dean might see it and chime in. Clive

Ding Dong Ding Dong.!! . . . . 24Vdc is correct for these drives Clive they only Take 30Vdc Max so don't want to release the Magic smoke.!!

OK, can someone just cast their eyes over the main wiring for my cabinet ( attached image ), a little bit of reverse engineering from other diagrams on here and adapted to fit my needs i think?

Ok well see a couple of things.

Don't see the latching Relay wiring.?

Don't see the point of the Green 240V Led just use Red Led that's on all the time Power is On. Use the Green Led for indicating System is Reset and Ready. I'd Also use 24V leds.

Don't Like the fact your using 1x Mcb for 3 x Psu all different sizes. You will be better having the smaller ones on separate Glass Din rail fuses.

ill upgrade to real drivers one day :), regarding the other PSU's the 9v powers the USB controller, and the 12v spins some fans on the drivers and the din 24v powers the estop thingy to kill power to the other psu's

Yes I had checked that out in the early post. I was just saying its a shame to use such low voltage drivers. ..Clive

OK updated to V3 now and I have added the e-stop / latch relay connections? removed the 9v and 12v PSU to avoid confusion at this point and ill upgrade the fans to 24v and run off the Din Rail PSU. Am i close correct with the relay / contactor connections?

Thanks again

Ive attached a schematic of what i think the latch circuit looks like:

S1 = Go push button NO
S2 = E-Stop NC
S3 = Stop Button NC
RY1 = double pole latch relay NO ( can you also do the same with a single pole? )
RY2 = contractor DC coil

Thanks

Surly a stop button should not be the same as E-stop. ..Clive

Where would you place a stop button to release the latch? or not required?

When you press E-stop or the stop button then latch is dropped because power is removed from relay. So in your schematic E-stop and Stop are the same.

Same in Mach3 if you press Stop while machine is moving then consider it just the same as pressing E-stop button. You will lose position and need to Re-home before continuing. Only Feedhold is safe controlled stop.
