I am looking for help on Emcomat 8.4 Mill Head wiring

[OmarA]

Hi Guys! I was wondering if anyone can send a picture or tell me the wiring hookups for the Emcomat 8.4 Mill head.

I have the manual and still can't figure out the correct wiring.

Enclosed is a pic of my connection box.


Thanks!

Three phase or single phase motor? Are you able to scan or photograph pages from the manual?
The information should be there, we can help you interpret it

Hi Mark thanks for replying…. It is single phase 120vac.

OK good. Now, do another close shot of the motor as in post 1, only this time move the wires so as to get a
better view of the terminal block behind

This was the original mill that worked with the lathe…. Here is a closeup picture

I see the wires are connected in that picture- did it not work in that configuration?
I'm thinking it looks correct except for the black wire which should move up to the upper right post

PS this thread should be under "all about electrical" or the Emco section

This configuration did not work…. I will try moving the black wire

Any luck?

The manual clearly shows Black wire "W" and "W" is embossed on the connector panel. So why would you think the Black wire needs to go to the "Y" connection? Does anyone have a picture of their wiring box?

We don't know if the wires from the motor to the terminals are in their original positions or not- so the letter designations may not match up.
From the diagram the black wire must be connected and not hanging free; likewise, the single wire on the upper right hand post should be connected
to one of the three control wires so it stands to reason the black might go there. We just want to see rotation even if the direction is reversed.
Try it and see, it should run. The direction can be inverted if necessary by swapping two leads.
