Fanuc Motor Specs

[JerryFlyGuy]

Hey fella's, I've not got a set of yellow cap's and I'm working to figure out what the pin-out's are on these for both the motor DC and the encoders as well.

Also if someone know's what the shaft taper is on these yellow cap's it'd be appreciated!

The motor's that I've got are A06B-0642-B012 and B211.

It appears as though the B211's have a brake on them which is controled via a small 4 pin connector down near the shaft end of the motor?

Lastly, I'm looking for a supplier who sells the female connectors for these motors, anyone got any sites which have these connectors.. or at least some standard make/model?

Last question; It appears as though one of these motors got dropped in shipping and the threaded portion at the end of the shaft is bent. The shaft itself looks ok, just the thread from the necked area outwards is bent. If I try to straighten this is it just going to break off [anyone know what these shafts are made of?]???

Thanks guys..

Are you sure they are encoders?
If you look on the Cannon-MS connector, there is a MS number, if you can get the number off of it I can give you the mating connector number.
Electrosonic in Canada and there are several US suppliers, I usually use Digi-key, if US shipped. (They are not cheap)!
There is a previous post on the Shaft taper details.
The brake can be 24VDC or 100VAC.

Hey Al, I'm sure of nothing.. they are supposed to be encoders.. but.. I've not pulled the caps to have a closer look. I think there is a tac in there as well but again.. not sure..

I'll have a gander at the connector tonight.. see if there isn't a number on them. I have no doubt they are not cheap.. thank goodness I only need to buy two sets.. [two motors came w/ them.. hey.. maybe those connectors already have numbers on them.. I just assumed they were OEM Fanuc connectors.. never thought to check.. ]


I'll do another search on the taper.. must have missed it on the first try..

You wont need the tach, if you pull the cover you might see a resolver these have 6 leads and are about 1" in dia.
The mating connectors should have a number, the main suppliers are Canon, AMP & Amphenol.
This might help on the taper.

I'll pull the cover and have a peek.. might post a pic to boot.. your right the Tach is useless for my needs... as is the resolver [I think] so hopefully it's a encoder.. the case said Pulse coder [or something like that..whatever that means]

Found that thread about 2 minutes before ya posted.. who'da thunk to put it under Fanuc! [or who was the idiot not to look there ]

Thnks

Here is what the resolver look like.

Alrighty.. head way.. the 'pulse coder' is a A860-0300 T001 2000P which would seem to be a 2000pulse [500quad??] encoder? All four of them have this same unit. [well I'm going on a fairly safe assumption that the matching unit's [they came in pairs] are the same]

Pictures are attached.. [cheap camera.. crappy pictures]

The Plug that I need to duplicate is a Ms310 2A18-10P if that means anything.. it's a 4 pin male [I need the mating female]

I've also got some other plugs on the other pair, no numbers but thought you might recognise them.. [long shot].. The two larger are connected to the encoders and the 4 pin are the brake [I assume..] it looks like there is only connectors in two of the 4 pins.. I suppose w/ DC brakes there is no.. correct + or - to wire to?

Thanks Al

The armature connector looks standard, in most cases two each of the pins are connected in parallel to allow for two conductors for each + & - DC.
Check with an ohm meter.
This connector appears standard metal MS, but unless it is the photo, the others appear to be AMP CPC plastic connectors, if so I have never seen these on a Fanuc motor before?
The brake is normally a 2 pin connector. My 110VAC brakes I have measure 290ohm.
I do not have a DC brake to measure.
The encoders will be 2000p/rev which will give you 8000 resolution if x4.
Does the encoder have an MS connector on the encoder case?

Al, you truely are "The Man"..

First some background. There are 4 motors, they came in matched pairs from different homes. The MS connectors for the encoder and "power" side on the first set, I have matching cables.

On the second set, I don't have any of the connectors. The "power connector" is a standard MS but on the encoder and the brake someone has changed out the MS for some 'other' connector.. if you say an AMP CPC then that's the first style I'll track down and measure to see if they fit.. They are both [encoder and brake] females while all of the MS stuff is male [on the motors].... fun fun..

I'll check the Ohm of the brakes and see what I get.. I've another brake which uses 110vac on my machine right now.. I'll have to test that as well.. see what it shows.. if it's similar to yours and my motors are also.. then it's safe to say it's a 110vac brake, if not.. I guess 24vdc probably won't hurt it, if I give it a try..

Know of any place where I can find a labeled wiring diagram? Two of the motors have the original MS connectors so I should be able to cross those w/ the wire colors on the 'odd' connectors and match the pins..

Thanks again Al...

[Btw, I was in your fine city on Saturday... thought about emailin ya.. but turned out I didn't have any time.. I did get to see Tom Petty while he was in town.. [suprise to me.. the guy's I was flying just plopped down a ticket for me and said "your going.." .. who was I to argue! ]

Hi Jerry, sorry I missed you.
When looking for the mating connector, either MS or CPC, this can get tricky because both a socket or a plug can be male or female.
The CPC uses a term normal sex or reverse sex, this refers to whether the screw connector itself is a male or female, not the connector pins themselves.
The CPC has a square acme-like thread.
One of the web sites like DigiKey or Mouser show the pictures.
Did you want the original encoder connections? I am not sure if I have the colour code however as the MS connector is usually on the encoder itself.
Al.

[JerryFlyGuy]

Ya woulda been great.. oh well.. next time..

Ya the CPC plugs have a male thread [very ACME looking] w/ the female pins sockets.

I'll have a gander at Digikey.. I gotta order some other stuff there anyway..

Do you have the original encoder layout? That way I can figure out how to connect to my current wiring.And then I can also match up w/ the CPC plug is wired like.. I can check the back's of the plugs to see which wires are going to which pin's and then make myself a xreference drawing..

J

[Al_The_Man]

This may help, it is one drawing that show the encoder with a MS connector, I may have the encoder colour code somewhere.
You will notice the 100vAc brake, with tap for 50/60hz.

BTW when ordering CPC parts, it pays to get the pin remover 305183. If you use a few of these connectors it will come in handy!
