MPU11 / GPIO4D to Fanuc Servo Drives

[Magneto]

I'm hoping to get some recommendations of how to interface the GPIO4D to Fanuc servo drive amps #A06B-6047-H003 (also Fanuc #P470673 or #A20B-0009-320/xxx, for future readers' interest). I've searched the board to no avail so far.

I've attached the wiring diagrams associated with these connections to get your comments as to their equivalents on the Centroid board.

Drive Side
In the images, you'll see the following labels:

VCMD
OV -> EC
TSA
TSB
OVL1
OVL2
VRDY1
VRDY2
ENBL1
ENBL2
PRDY1
PRDY2
ALM1
ALM2
ALM3
COM

And a pinout view:

Feedback Side
The encoder side is even more cryptic here:

But this should help:

Thanks.

Actually, I'm going to call this one largely resolved for now. Look what valuable document I just found:

http://www.ajaxcnc.com/downloads/Techni ... ns/233.pdf

This covers my X axis drive situation perfectly.

Note that these Fanuc drives require an OPTIC4 interface board, as described in the tech bulletin.

The GPIO4D alone cannot provide the necessary simulated tachometer signal to the drives.

Actually, according to Ajax, not even the OPTIC4 is compatible with these Fanuc drives. They looked over the specifications and said they would not be able to support such an installation.


Yaskawa, it is.
