Panasonic MSD043Axxx Servo Driver pin outs????

[JAZZCNC]

The connector is nothing like the one you show (which was my point).

All I want to know is which is pin No 1 on the Servo Unit.

So maybe it would have been a good idea to show us the connector you have.?

But all the same, the diagram shows which pin is number 1, which when looking again I'd say it would be how you have drawn it in the second diagram, so yes I'd say you are correct but still if you are unsure and there are no markings I'd check it out more because very easy to let out the magic smoke out if wrong.!

Picture no 2 in the very first post

"Hi, I have three Panasonic MSD043xx servos on a Triac" - then picture two is labelled "MSD043xx" in large red writing.

I know the drive model, I referring to showing us the rear of the cable connector you have because you say the 3rd diagram doesn't match, so what do you have.? plus those pictures were a bit shit so can't see the connector on the drive very well.

Just because the front of the connector shows two rows of pins doesn't mean the rear of the connector has 2 rows, in fact, many have 4 rows just like the diagram shows. See the pic of one of our Lichuan servo drive connectors to get the idea.

Use a meter to identify the Gnd pins, this should hopefully determine the layout.

Take a detailed photo of the front of the drive itself showing the connection.
I did find part number:
10136-3000VE. Connector.
10336-52A0-008. Shell.
Conn part no, search, came up at RS components.
Shown as discontinued product there.

Numbers were taken from manual for MSD series that came up when searching your drive number. Config looked the same 4 rows.
Technically, there should be a part number for connector/shell in your manual either above or below the pin config image.
Also part numbers for different encoder cable options depending on motor driven.


Double/triple check any cables after soldering, with a meter.

The rows in the manual don't make sense as explained previously in my last reply to JAZZCNC.

The fact that this guy in the USA is selling generic cable for Yaskawa, Mitsubishi, Panasonic servos would also suggust to me a standard pin numbering for the port.

Ok, now I can see the connector properly I can tell you that it's exactly the same connector as the pics I posted.

So in your original post, the 2nd pic is correct if viewed from the front. BUT the manual diagram is also correct when viewed from the rear of the connector as you would normally wire the connector.

As in the 'plug-in to the drive' side is configured as long rows......
The solder tabs on the back 'cable side' are configured as the diagram.

Just make sure you solder the numbers in the correct order.

I'd prob get a pre-made scsi cable at needed length and chop one end off. Then use a meter to mark up the pin numbers on the cut ends.
That's me being too idle to solder though!.

There are breakout /screw terminal connector pcbs you can use if you want to keep both ends of a cable intact.
