Looking good Joe
I removed my 12v supply and simplified everything to run off the 24V supply. Just need to pair up 12V devices in groups of 2 in series . E.g. 2 fans or fan and motor
Less things to go wrong and less space required in the box
Also I'd add a switch to the water cooled spindle pump - looks like it will run all the time which will be annoying plus may heat the water a little
I have a 12v supply on order but it was only cheap. Clive has also suggested running all from 24v. I already have two 12v fans but could get one more and run in series with the 12v pump I guess. I was going to use a mcb instead of a fuse for the pump so I can switch it off with that?Quote:

Anyway dump the 12V and wire the Fans in series and buy 24V pump.
I would not run a 12V fan and 12V pump in series as they would be different VA's therefor they would not give a 50:50Quote:

It's a new addition because I have a 12v pump but not a big deal - a 24v pump will be cheap enough in the scheme of things! You are right about the VFD switching the pump on so guess being able to switch manually on the mcb will not be all that useful.Quote:

Ah, ok thought was unusual for me to miss something obvious like that.!Quote:

Regards the MCB then don't really need MCB but the suitable fuse is required to be safe but only in case of short it's not something you'll use has a switch.
The VFD Relay will handle this for you and because you'll only ever run the pump when the spindle is spinning you'll have no need to manual overide.
Thanks Dean - do you tend to screen your alarm signals between drives and IP-M?Quote:
