Electronics for New Machine + Chinese Spindle + VFD

[mturneruk]

Hey guys...

Lots of progress here. Really pleased with how the machine has turned out so far.
Super strong and bloody heavy. Not a bit of wobble in the Z. It only took 2 days to assemble all the parts in the end.



Lots still to do.

Jazz - Got a couple more electronic questions if you would be so kind.

1. Can you confirm that a 1n4007 1000V diode is ok for the fly back diode on my 24v relay and that the line on the end of diode goes towards the PSU and not the other way around ?

2. I've got my transformers. The 24V one I've received is only 1A. I thought it was more than that, but no.

Basically it's driving the relay (which has a coil current of 69mA) and 3 prox switches. The only data I can find on these switches is that they have an "output current" of 300ma.
So does that mean 300 x 3 + 69 = 969ma, e.g. Just less than 1A so ok ?

3. The relay I've got did not have a base. Would it be ok to mount the relay upside down and use spade connector crimps ?

4. Is it worth it to run earth fly leads from panel to panel in my multi-panel case. It is painted so there is no conductivity between some of the panels.

Thanks Guys.
