Fadal 2016L update to Oka

[wagdamotta]

Hi
I need help
I think in update the control of my Fadal 2016L to Oak control, any one can help me with inf. Or if any one did?
I converted my PM25 with acorn12 and works very good the only problem the machine is too small.
Thank you for any help

Different Fadal machines appear to have used different servo drives and motors over the years.

What servo drives and motors does your machine have?

What model spindle drive (VFD) does your machine have?

I have AC servo drives and Baldor (adjustable speed drive)
If you need i take pic.
Thank you

Assuming it has AMC or Glentek servo amplifers (perhaps with Fadal labels on them), then you would be better off with the MPU11 and GPIO4D board combination, rather than the Oak. With MPU11+GPIO4D instead of Oak, you would lose the ability to have servo axis load meters, but would have an easier time wiring the drive enable, fault detection, and encoder interface.

The AMC and Glentek drives have a 5VDC, active-high "disable" input instead of an active-low "enable" input. This requires interface relays, or at a minimum a 5V connection and a pull-up resistor, between the control board and the drive. This is easier to introduce with the terminal arrangement on the GPIO4D.

The AMC and Glentek drives appear to have a 12VDC fault signal, driven both high (fault) and low (okay). The Oak fault input opto-coupler is internally supplied with +24VDC, and therefore will conduct (and read closed/okay) when the drive is okay, and also when the drive is faulted. The GPIO4D fault input can be supplied with +12VDC instead, making it compatible with the drives.

The AMC and Glentek drives require that the CNC control provide 5VDC to power the encoders, through header J6. The MPU11 encoder plugs can supply 5VDC. The Oak axis-interface headers cannot.

Hi
Thank you for the reply, sorry for the questions, the MPU11 is better and easy the Oak?
I can use my ATC with the MPU11?
I can use my AC servos that have in my machine?
If not what type servos i have to use?
How difficult for make the up date?
Like i told you before i did the convertion on PM 25 before and works very well.
Thank you for the help

The MPU11 runs all the same software that the Oak and Allin1DC run.

If you have AC drives and motors that happen to be the same as the ones I found in the VMC6030, and yours are in good working order, then you should be able to use them.

If you want to replace them, you should replace them with good (i.e. Yaskawa or Delta) modern digital AC drives and motors. If you are going to use Yaskawa or Delta AC drives and motors, then you can (and should) use an Oak control unit instead.

Tomorrow i going take pic of the motors tag and i post here for make sure what type i have and what i need to get from centroid for up date my machine.
Thank you

Hi
I just send some pic to Centroid sales to Att: Livio
Thank you
