UC300eth UB1 wiring help.

[Nickhofen]

I purchase the UC300ETH-UB1 combo for my home build cnc, to drive 4x4NM stepper motors with
4x AM882H
1x72Volts PSU 7Amps
2x12 volt psu 330watt
HY VFD with 2.2kw water cooled spindle
NPN proximity switches.
The wiring is a headache for me, and this is what I have design until now, can anyone check and tell if I am at the correct path?

You can take a look at my schematic on the pilz s5 thread

Not sure 7 amp is enough...

72v could be a little high 68v could be right to grt margin for back emf

Limits or home switch if limits don t connect it on you bob'

don't connect limits on you bob but a relay cutting the enable and power of drivers

Also you should use the am882 alarm.

For vfd to bob use the rs485...
