Haas VF-OE -- I/O PCB -- where do these connectors go???

Hi,

Please see the hi-res photo here: objectivelyspoken.com/uploads/20210124_142711.jpg

This is a machine just delivered to my garage that I have yet to power up.

Before the machine was moved, the technician removed the Regen Resistor Box at the top of cabinet. This means he disconnected the regen cables. I have now connected the regen resister cable, and the regen overheat connector on P20 (above P15 on the left). According to the Mitsubishi spindle drive instructions the Regen Resister connects to P and PR so this seems where it should go.

Now I have noticed there are four 3-pin male connectors on the right side of the IOPCB that are bare:

They are P57, P58, P5(110), and P54(350).

There are also 5 female connectors hanging loose. (You can see them hanging on the right just in the shot.)

Er...did the technician remove these to get the Regen cable loose?

Must I plug them back in?

Does anyone have a shot of their cabinet they can email me showing what is plugged in and what is not.

This is a 1996 model. I don't yet have three phase power installed.

Thanks!

Paul

Do you have a copy of the wiring diagram? It has a list of the cables and where they go.
For one, connector P54, cable 530, is for the servo brake on the fourth axis.
Regen resistor for the spindle or the axis servos?
My '91 VF-1 has a power distribution board and the servo resistor plugs into that.

I should have said that the five dangling female connectors are in series on the same cable.

Below are the relevant sections of the wiring chapter. There is no information on P57/P58. It does not seem intuitive that P5+P54+P57+P58 should be connected together -- ??

Further below is the PCB 32-5020 connector list. It shows cable 110 to P11 which is a 2-pin connector. This makes no sense since P5 is 3-pin. I cannot find a board in the cabinet that looks like "PCB 32-5020". This is named the "SDIST PCB", but nothing in the cabinet looks like it. I checked the 1996 and 1997 manuals and they both have this same SDIST board.

see my reply above

I think I found a clue.

On the left is the 1996 manual. On the right is the 1997 manual.

Everything connecting to the SDIST board was removed. These are P5/P18/P32/P43.

A blank under the column "PLUG #" does not seem to mean the plug is unconnected. For instance P23 has a wire to it and labelled blank.
