For the relays.. is this about the e-stop relay we talked about?


Can you list the stuff you want to control by relays? You mentioned an ub1 has 3 onboard so...


Maybe pneumatic valves, pumps , vfd?

What needs switching on/off more than the 3 relays available to you?

I would use the onboard relays just for low current stuff like the remote on / off for the vfd , the spindle cooling pump, maybe chip clearing air valves and or liquids.

Hi Bert
Thanks for the reply.

The relays that the card has onboard are charachterized as ''signal relays that should never used as power relays, they are intended to convey signals such as fwd and reverse to a VFD ...However please take care , as the contact of these relays can carry a max current of 0.5 amp at 120V AC or 1 amp at 24V dc.The user must use an external relay if the load requirements of the device will exceed the current rating.''

This is why i mention the external relay connection.
To answer the other question you put, I want to connect the maximum I can on this card ,water pump , air nozzle etc.

BTW doesn't your design allow for 4 combined end / home switches?

Do you plan on using all 8 off them?

like 4 home and 4 end?

I read about this a few times on the forum they can be combined in some configurations.

I have no hands on experience this subject (and a lot of other things) :-) yet.

Grtz Bert.

I am going for this configuration because my previus cnc was wired like that, if there is a better way of course I prefer it.

You are speaking about traveling proximity switches, right?
