Panasonic MSD043Axxx Servo Driver pin outs????

[JAZZCNC]

I've counted inside the connecter and there and theres 36 connections (18 each side - not 19 and 17 as shown in my numbering...sorry). Then on the other end (connection to the AHHA board) is a 36 pin serial connector. Would they really use a 72 pin connector when they only used 36 of them?

Also the pin out picture you posted (from the manual) uses 4 rows of 9 pins (making 36 pins). Which is also just strange.... if there was more pins would they really only use the top half?

Yes, they would use a 72pin at the other end if that is what was needed on the board, this is not uncommon. My Yaskawa Spindle servo drive uses a 44-pin connector but only 6 of the pins are used.
Likewise, it's not uncommon on a 36pin connector to only use one row or less.

It's also not uncommon for 2 or 3 cables to go to one 36pin connector so they make use of the pins for several boards. We fit industrial controllers and they often come with connectors using several cables.

The connector looks like this https://www.ebay.com/itm/233770293586

Go through the pictures and you can see the front end of the 36p which shows 18pins each side.

Yes but look at the rear and there are 4 rows of pins although it shows a 26pin, not 36 they are just the same with more pins, and the diagram in the manual is shown as if you are viewing from the rear, not the front which is where I think you are possible getting confused.?

Do you have the cable connector.?
