Need Help ! Trak CNC2 conversion to Centroid Allin1DC

Post by Rui26 »

Hello from Portugal
I am thinking in upgrade the old trak cnc2 control on this machine and i have some questions maybe someone can give me some lights
This is the machine
Foto1.jpg
1. When i bought the machine the seller tell me that it have fanuc motors, i can´t see data in the motor except 70 V. Anybody knows these motors?
5.jpg
2. I supose i have to change the encoders..
6.jpg
3. The machine have linear scales and encoders in motors, can i only use new encoders ?
7.jpg
4. Can i use old transformer? How do i know the voltage that the transformer send to the motors?

Thanks!

If the transformer was previously working with your motors, you should still be able to use it. You will need new encoders on the motors. These encoders will connect to the AllIn1DC for the closed loop positioning. This is all you have to have to run.

If the glass scales are 5V differential quadrature output, you may be able to use those for additional positioning feedback to improve accuracy. You will need the Ultimate level software and probably an ENCEXP board to interface the glass scales.

Thanks !
The Trak CNC 2 is working, i will try to measure voltage in the drive output to the motor with the machine working . I think i will need one rectifier like centroid sell once the old rectifier is inside de driver box 🤔. The scales are not the glass type. I will remove them and buy better encoders that suits allin1dc specs.

I was wondering if the 120 volts limit switches can be used in allin1dc control 🤔

While those limit switches are rated for 120V, I sincerely doubt that are being used at that voltage. Usually machines use 5, 12, 24 VDC or VAC for signalling. It opens up a huge regulatory can of worms when you use high voltage for signals.

Good Morning
Thanks for the support
Since I saw the possibility of upgrading the old mill to a more current system, I was motivated in this project.
In the meantime I found this film made at an American university, where they made several retrofits to prototrak machines.
In these retrofits I saw several pieces identical to those of my machine that were used: motors, limit switches etc. so it gives more security to advance this project.
I would like to see these projects on the spot or talk to whoever made these conversions, it would be interesting.

I leave the link to the movie I mentioned above:



Greetings

Good Morning
I have the following question:
My machine has only one limit switch per axis, in X and Y. The switch is in the middle of the table and the stops that activate the switch are at the ends of the table. The question is whether it is possible to use the allin1dc control with only a limit switch on the X and Y axis? I think so because I have seen it on a movie on the internet but I would like to know if the solution is easy or requires many adaptations ...

Are you sure there are not two switches within the body of the switch assembly?
Picture please.
You can get by with one home/limit switch per axis. You just have to set up the soft limits properly.
