pin out pulse coder A860-0360-v501

A860-0360-V501 it takes cable A860-0360-T201

I have acquired one of these motors to run a 4th axis. the brake releases , the motor seems to test ok, but the encoder is definitely wired differently than my other motors. and is wired differently than the pinouts I have found in the posts. If any one has the pinout, or can tell me how I might determine the wiring format for the encoder, I could sure use some help. thanks

That is a 2000p/rev incremental encoder.
Is the insert # in the MS connector a 22-14 or 20-29?
Al.

20-29 is the # in the center of the connector

This should show the connections you have for the 20-29.
Al.

Al, unfortunately the chart doesn't add up with my pin out (observed)

here is what I have with lead color nd connection to the inside wiring leads.

A gray P 8
B -
C -
D black P 10
E -
F violet P 7
G pink P 9
H -
J orange & pink P 14
K red & pink P 13
L blue P 6
M -
N orange P 3
P -
R brown & green P 12
S green P 5
T yellow P 4

pins 1 and 2 loop back inside the motor to a pair of white motors which I assume are to a heat sensor.

the motor is an A6/3000
A06B-0128-B175#7000

Thanks for your effort thus far

I found info on the motor number, and they show absolute encoders for this model.
It is probably an Alpha series?
Al.

yes it is an alpha series, I guess I should have typed it out. I suppose this means I have to get a new encoder. I was planning on running it with a Granite Devices VSD XE so I wont have to have commutation from the encoder.

You could look for another Fanuc encoder, I can't remember whether the encoder taper mount is the same as the differential.
I have converted some Fanuc's using a circular aluminum plate mounted using the 3 existing mounting holes, to attach the encoder to.
Then screwed a 8mm machined shaft extension using the existing 5mm centre hole. Misumi USA sell these machined rods in different sizes.
I have used the NOS through-hole encoders that Renco have listed on ebay.

You guys ever had problems with circular interprelation where it does not give a alarm but the x axis just seems to quit and then decides it needs to play catch up with y but never gives an alarm or error we have had this machine apart several time but have not had any success at the problem fanuc has charged us alot of money and they are still scraching there heads NEED HELP IF ANYONE KNOWS

You did not say who the MTB is, what do they have to say?
Al.

Al The Man must celebrate 10000+ posts!

Is there a problem in "radius method" of circular interpolation also?

"Centre method" requires that the specified centre must lie on the perpendicular bisector of the line joining the start point to the end point. If not, the "error" is taken care by a linear motion along one of the axes, at the end of circular motion, to reach the specified end point, provided the error is smaller than a value specified in a paramater.

The error is not a small error the error comp is set to .0025 and it moves over .150 and then continues on like nothing happened for about 5-8 passes then does it again in a different location but gives no alarm or error message

Did you try radius method?

i need connection details for spindle external encoder on control fanuc 18i

Hello,

Sorry for resurrecting an old thread but it should be in topic.

Al, I have a similar motor with 20-29 marked inside the CANNON MS Connector, from one of your other posts I have found :
"Fanuc DC Motor 5
Type: 0-2500M 2500 pulse encoder"

Is it the same encoder on the motor in the picture "TYPE 5-2/3 N" ?
I unscrewed the MS connector from the cap and looked inside, I could barely read Tamagawa, and the encoder appeared to be mounted off axis/center any idea ?

Any hint about the proper way of removing the cap in a non destructive way ?
(it is apparently glued with some blue stuff, from pics on the web)

Attachment 502942

if it's an Absolute encoder, then what kind of protocol does it use ? Proprietary ?

Datasheet ?

Thanks very much.

Generally the proprietary encoders are used on the AC (Red-Cap) servo's.
The DC generally used a standard quadrature encoder.
Not sure of your description of the encoder?
Would need the Fanuc model number to confirm, from that the type and resolution could be known.

Thanks very much for the reply Al !

The control was an old Fanuc 0MB / 6MB...if it can help :) an there was no sticker on the encoder from what I could see, it was laser marked on SS encoder housing...
" BRUSHLESS
TYPE
INPUT
TAMAGAWA"

And it is clearly way off center, to the side of what looks like the bearing flange/housing, but could be part of a larger encoder...

Please, how would you remove the black cap from the motor in a non destructive way ? to take a closer look at the encoder ?

I have tried to pry it open but it seems to be glued, and I am afraid of using heat around sensitive components.

From the Date on the motor tag shown and the FB unit being off-center I'd say it's an inductosyn resolver.

Hi guys,

Had a hard time prying the cap off with a screw driver, wedged between the housing and cap... had to lightly hammer(M16 hex bolt head) on the screwdriver.

Right on the money freaky ! it's a resolver =>(the word that should not be said) geared to the main shaft

TAMAGAWA TS530N30E9 3000Hz BRUSHLESS RESOLVER

It also appears that it has another feedback below it, which looks like a small armature with commutator and two wires(red+white) coming out of it... is that a tacho ?

Any straightforward way of converting the outputs to something usable ?
Any affordable drivers for these ?

Thanks very much !
