Panasonic MSD043Axxx Servo Driver pin outs????

[Nemo1966]

Hi, I have three Panasonic MSD043xx servos on a Triac I am rewiring. It had a AHHA Artisan Dos system on it before with their propriety boards wired in. So had to remove all of those.

Anyhoot with a lot of help (thanks to joe.average and Andrew over at the Warp9 forum). I have managed to sort out the wiring in theory. However the manual states the pins numbers but not how they relate to the actual connection on the unit. The connection looks like an SCSI 36 pin.

31023

I am thinking that this may be the case (below), but would like confiirmation either way please.
31024

The manual also has a diagram... that I think might be a optional cable connection for the unit????? The image with the trapeziode seems to denote a connector but doesn't seem to follow any known configuration?????
31025

I have the original "pre-made" cables, but I feel these may be a special cable for the AHHA/Artisan boards??? (again guessing). They are labelled "Simplatroll M2-544854" but I cannot find any information on these.

Any information would be gratefully recieved

thanks

I'm not quite sure what you are asking here.? You say how they relate to the connection on the Unit.? What unit are you talking about.? Do you mean the Controller or breakout board if so then you don't say which controller or breakout board and without that, no one can help you really?

The diagram of the pinout for the drive is self-explanatory really, you decide which of the pins you are going to use and connect to the pin numbers on the 36-pin connector. Then at the other end, you have the choice to wire to the same pin numbers if it's 36pins or if the controller or bob has its own pin numbers on say a 44 pin connector then you wire to the relevant pins this requires. Often on the connector at the other end, you will pull each pin wire and send it to several places inside the control box.

We need more info on the "Unit" you talk about.

Hi,

The unit in question is the Panasonic MSD043xx series servo. Not worried about the breakout board side. https://industrial.panasonic.com/content/data/MT/PDF/MINAS-Xseries_manual_e.pdf

The first image in my above post shows the pin outs for the panasonic unit (from the paperwork included with the miller). But the manual does not state which pin on the physical drive connector is pin 1.

Picture 2 is what I "guess" are the pin numbers on the connection actually on the unit and the corresponding connector that connects to that.

The last picture is of the the cables that came with it, but I think they are proprietry to the Artisan boards. So of no help to me. But I can cut the serial connectors off and still use the cable.

thanks :thumsup:

A bit like this one which is a db44 for a delta.

The loose ends get connected to the relevant pins on your breakout/controller you want to use to control it.

Looks like a 36pin scsi on the panny to me.

Something like this and chop it to loose one end (depending on whether need male/female).

Or solder your own 'kit' connector together.

It's the scsi 36 pin on the actual drive i need to know about.

[Nemo1966]

In short... is this correct or not?????

The attachment not working for me.
I added a couple of examples in my previous post.
I don't know whether you'd need male/female.
You'll have to judge it against your drive CN connection.
Likely to find something on Aliexpress (if your not in a rush).

Ok, can you post the manual or a link to it.

[JAZZCNC]

Ok, I found the manual and it looks to me like the diagram below is what you need, I know it says for external equipment but I just think that means when being controlled externally rather than using the built-in control functions and using as stand alone drive.

Now I'm not too familiar with SCSI plugs but did a quick google on the SCSI and most show a 4-row pin arrangement. However, as it says in the manual you need to confirm the pin location on the connector matches.

This is not an unusual arrangement on servos connectors, I recently retro fit an Hurco with Honda 44 pin Scsi connectors on Yaskawa servo drives and they used 4 rows that were similar in layout to those.

All this said I wouldn't connect up to the servo until you have verified the pin layout because it will be very easy to blow an input if you get it wrong.

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

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 :thumsup:

"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.

I see what you are saying.. but if you look at the first diagram I posted there are only 36 connections on the Input/Output control cable CN-I/F.

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?

The whole thing would be so simple if they just had Pin 1, Pin18, pin 19 and 36 marked on the device. I posted hoping someone had fitted these type of drives before and would instantly know. It looks like one of situations where if you "know" you know, but if you don't... you don't and there no way to actually work it out.

I do appreciate your time and effort though, it's just very frustrating trying find out this info that should be readily available in the manual.

thanks again

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.

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.
https://uk.rs-online.com/web/p/scsi-connectors/1761986


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.

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.

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.?

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

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.

Ah yes I now see what you are saying, I have a cable already I wanted to know the pin numbering from the FRONT of the cable connector. I didn't realise that they looked different from the back.

The cables I have are the 4th pic in my original post. So I wanted to cut off the NON-Servo connector (36 pin serial) and trace back the signal with a multimeter and re-use them.

Looking from the back (like you say) then it does match what I thought on the servo 1 - 18 down the left side and 19 to 38 down the right side. Which will match the from of the FRONT of the servo.

thank you very much - sorry for not clicking sooner :joyous:

No problem, Servo manuals are not the clearest of things, and if you are not used to these things it's not always obvious. The good thing is your sorted now.
