Yes, this applies to their first generation of brushless motors/drives 
from 1984.  I didn't know that these existed, thanks! It makes sense, as 
these could be used in place of their DC brush servo amps without 
changing the control.

Thanks!  The problem with Fanuc is they made a VAST variety of products, 
each just a little different.  I try to keep track of which serial 
encoders work with my converter boards, and it is maddening.  They have 
hundreds of different models at the same resolution, all with slightly 
different configuration.

I only know a little about the servo amps.

I think I had the dividing part number wrong but for example a Fanuc 
A06B-6050-HXXX is definately a AC servo drive with analog inputs:

Well, my  stuff does NOT use the existing Fanuc servo drive.  I do have 
six-step brushless servo drives that can be run from my PWM controller, 
but they are not capable of driving the larger brushless motors to full 
peak torque.  The first brushless drives used SIX PWM signals from the 
controller to EACH drive.  I don't think they ever had an analog-input 
servo amp for the brushless motors.

There are some other drives from AMC and such that can deliver more 
current and take PWM input and Hall signals.  My Fanuc converters (two 
models, for first-generation and later serial Fanuc encoders) will give 
the Hall signals.

 Subject: [Emc-users] Use Fanuc Servos & Amps with EMC2
   
Hi:
 
Is there a simple solution that some one has developed allowing EMC2 to connect 
to the Fanuc  drives and red cap motors?  A MESA board or something like that 
that could be wired inbetween like a converter?   I was looking through the 
achieves and noticed lots of issues but stopped after reading the 23rd entry of 
over 1200 due to brain overload. 
 
If I was understanding the notes correctly it seems like Fanuc has their 
proprietary communications system that isn't easy to interface to the standard 
+- 10 VDC signal with incremental encoder feed back. 
 
I am looking at a late 80's machine with an 0M control that could be ideal for 
an inexpensive retrofit if the motors and amps can remain. 
 
Thanks for your help inadvance. 
 
Best regards,

Steve Van Der Loo

It depends on the vintage of the equipment, of your motor drives part number 
ends in 6057 or less, you have a analog +-10V drive which is easy to 
interface, but if your drives part number ends in 6058 or greater, you have a 
digital drive (PWM from controller, 2 analog current feedback channels from 
drive = tough to integrate)
