After purchasing a Camsoft retro for my old P&W v-mill (1979-5M), instructions said to wire 6 wires from the servos & 6 wires from the encoders.
my problem is i have 4 from servo & 13 from encoders. How can I find out which is which ? Am illiterate in electronics, but still trying to get something going. I have a vom (not totally stupid), I have designed & built some very unique items. Thanks :drowning:

Not sure what the 6 & 6 your are refering to, what type of motors, encoders and drives are you using?
If you are using a Galil card, the standard incremental differential encoders inputs allow for 8 encoder wires, +v, Common, A, /A, B, /B, I, /I.
The servo motor goes back to the drive, and the connections between drive and Galil depend on what make and features they have.
Unless your motors are DC brushless and then the encoder may have commutation tracks on it the go to the drive.

Thanks Al, motors are brush Fujitsu-Fanuc, type A860-0300-T001 (about 5" dia. & 12" long), Galil is 18x2 or 1900 - camsoft - cnclite+
machine was built by Fanuc
Thanks again for the reply.

Are you using the Fanuc drives? Also Some Fanuc DC motors have resolvers (6 wires)!
If so you may have to change them for encoders.

Al, everything is Fanuc (they built it). What is the difference, (resolver or encoder), I would guess they are encoders.

Do you have the prints on the original machine? was this a Fanuc 6M control?
A resolver is usually geared using a ~ 10:1 gear train on the rear shaft.
It looks like a miniature servo motor.
You can get translators, but often its not worth it, it is better to change to encoders if thats what you have.

Al, I am sure they are encoders. 5M. yes i have the elec. prints

If you have differential encoders then you should be able to identify the encoder connections from the fanuc prints. There should be eight wires which includes the 5v and common.
They should be labeled similar to what I posted earlier.
Are you using the Fanuc drives?
Fanuc were often wired up with a pair for each conductor on the motor armature making it four wires, instead of the customary two.

[DYNO429]

Yes, Fanuc drives, the prints do not show the specific wiring from the encoders as I see it,(but remember who your are dealing with).
Thanks, Dyno429

[Al_The_Man]

What do they show? do they show a connector at least with notation?
If they show feedback notation like R1,R2,S1,S2,S3,S4 then they have resolvers.
They could also have a tach. If you can scan a sheet and post it in PDF or other, someone may be able to decifer what you have.

Thanks Al, will do.

Al, take a look at your e-mail
