Fanuc servo drive integration

If that is right, this has the 4 commutation signals and standard differential quadrature plus index.

In that case that means it will work well with the Pico-systems drive and either the hardware Fanuc converter or the bldc component, or with the Mesa drives and the bldc component.

There is some discussion on the cnczone thread between me and a chap with some Fanuc motors.

If its just a quadrature encoder (with commutation tracks) the next step is finding the drive interface specs or at least the correct pinout. Do you (clkeck1) have the controller part number? that might help.

"Al the Man" on the CNC Zone Fanuc discussion group used to be a Fanuc tech and has a treasure trove
of Fanuc docs. He has given me a lot of help in figuring out these encoders and motors so far.
He sent me some pages that cross-reference motor p[art numbers with encoder type, but the number
mentioned in this thread does not appear in that list.

I don't have the axis card number for the control because it did not come with the machine.

I ordered a fanuc manual for the drive and it should be here monday and might have a list of compatible cards.

Is there a benefit in running a 6057 "digital" setup with emc controlling the commutation and using PWM instead of using a 6050 "analog" setup and having emc just us a +-10V analog signal and letting the fanuc drive control the commutation?

I can get the 2 6050 drives for like $6-700 and sell the 6057's for $500


The spindle drive will be a separate issue as it is digital also but with my limited knowledge on the subject i believe it will not have the same commutation issues.

Thanks

I doubt there will be much performance difference, but I would make very sure the 6050 drives will work with your motors if you are going to change them. (and buying drives may just be opening another can-o-worms)

It may be that the 6057 drive will be easy to interface to, its just difficult to get info (so your manuals may help here)

Do you have the digital interface cables?

All the cables are still in the cases. They are just 10 pair shielded cables with 20 pin Honda connectors.

If I keep the 6057s what will I need for hardware for the 3 pwm outputs, 3 encoders, and 2 sets of fanuc inputs for commutation.

I would like to use mesa parts if possible since I am accustomed to it.
