I have an old troyke 4th axis with a fanuc motor. The motors part number is A06B-0313-B504 with servo amp A20B-1003-0090.
This is a 1990 vintage unit...

I would like to know what the number for this motor is for parameter #8420 so my machine recognizes it! If anyone has this in their machine, it would be great if you could let me know.
