Estop?

Right now I have the Estop ,NPN proximity switches and water pump.
I will add all the rest ,everything I can add and also a potentiometer for spindle speed control.

Try to make a diagram with the help of UB1 manual....

**Nickhofen** · 19-07-2018

This is what I come up untill now, no water pump or stepper motors yet added.
HY VFD is going to be connected according the second schematic.

Can you guys check the diagram to see if you find any issues, I add also the manual of UB1.
Also please suggest where to put fuses and relays.

Thanks,Nick.

One thing I see is that you seem to have fuses in the -ve line from the 72v PS that is NOT good practise and are not necessary. Also 5A may be a bit low
