Red Cap Fanuc Motors (late 1990's early 2000's) w/ LinuxCNC and Single Phase?

Thanks, sorry, I would have just supplied the pics but I didn't have them handy. The Model #/Motor spec #'s are:

A06B-0373-B075 for the alpha 2 models and A06B-0123-B175 for the alpha 3 axis motor.

The spindle motor is: A06B-0871-B390#0040 (the first letter A is obscured in the pictures I have, but it seems like a fair guess).

Thanks,
FDP

Wow, there's some real confusion here! The A06B-0373 shows up in my cross reference as a 1-0SP/3000 motor. The A06B-0123 does cross reference to an Alpha 3/3000, so that one checks out.

(A quick look at labels on eBay confirms that there are two "models" with the same "part #". I had no idea that Fanuc ever did this.
The specs on the motors look about the same, though.)

Anyway, the last 2 digits are the encoder type, and 75 means an A64 serial pulse coder. This gives 65,536 counts/revolution, and produces low-res absolute data immediately on power-up, so you don't need battery backup to have commutation data for the motor.

So, the Pico Systems serial Fanuc converter is suitable for these motors.

Thanks Jon!
I'll get in touch this coming week about ordering parts. I won't have the machine on hand for a few more weeks, so there isn't much of a rush on my end. I'll try to work on the wiring diagrams for the retrofit. Do you have any white papers or implementation guides on your site (I couldn't find any easily).

I was thinking of using Copley Xenus drives for the servos (I have one or two left over from another project where I never used them), it looked like your hardware is compatible with these?

Do you know what is involved in properly setting up the spindle for rigid tapping?

Kind Regards,
FDP

Just wanting to confirm your product is compatible with the servo in the picture?
