Now I have created an album in goggle photo,... let's see if it works now.

Feature of 'place inline' learned . It's good, will use next time.

Nice little machine. Keep us posted on your progress.
I DO suggest you benchtest everthing, one component at a time ON THE BENCH.
Get Acorn communicating to to the PC first
Get the physical Etop button connected to Acorn and tested.
Connnect one axis drive and one motor to Acorn and get it turning
Then connect the other 2 drives and motors and get them turning
etc....
Wire and test home/limit switches.
Remember to use the supplied Acorn logic power supply for use with Acorn only.
Any other relays, solenoids, you should use a separate power supply.
Also ALL Grounds and cable shield drains should go to ONE point, that is where the power supply earth ground lands in the control cabinet.

Hi,

I am sharing last iteration for cabinet design. I think I will go for this.

1) Layout:

2) Wiring diagram:

Now it's time to cross fingers and make bench testing of every single step. Will keep it posted.

The only thing i would take issue with is running the encoder signals through terminal blocks. I prefer to run encoders (or ANY shielded cable) point to point to reduce the chance of noise interference from other devices.

[martyscncgarage]

I agree with Tom.
Land the motor cables directly on the drives. No terminal blocks.

Point taken.

Thanks

[martyscncgarage]

Don't over complicate the build....more terminations you put in, the more chances of a problem. Land wires directly on Acorn Inputs and Outputs and connect motor wires directly to the drives.

Hi,

I received feedback from Wabeco; it is only meaning of the different pins.

In this drive folder https://drive.google.com/open?id=1nT4bl ... Mq2tE56XS0 you can find:

- Pin meaning
- Photos of hardware
- Video of reset after an e-stop (.mov)

I understand that when reset is OK, there is +24V point in the knob, and depending on position, connects it CW or CCW (pins 9 and 10).

If e-stop is pressed with spindle knob i.e. "Forward", and is restored again, it is needed to switch the knob to "Stop" and back again to "Forward" to move spindle again. Sounds like switching knob to "Stop" is kind of reset.

Regarding potentiometer, I think that it will need only the two signals from Acorn pinned to 5 (VFD common) and 4 (0-10V).

Most likely there will be need of more info because it is a little vague what I received. If this is the case, let me know please what it is needed to know further.

Thank you very much for your help.
