Do you have a third drive? Try and use it.
Yes, you connect all three alarms out puts to Input 5 because the are NO outputs.

Do you have a DB25 make breakout board to plug into the DB25?

Also under the advanced tab, wake sure step frequency is 100,000

oops!!!. I had pulse rate setup 200k steps/second.
Setup to 100k and both work fine and smoothly.
I hooked +ALM of drive 2 to IN6.
How would be the wiring if I want to use only IN5 for Drive OK for ALL drives?
Thanks Marty!

All 3 -Alm to Acorn Power Supply Common
All 3 +Alm to Input 5

Hook up the third drive and motor and check them.

You may be better off connecting the drives to the DB25.

What is the actual difference if connecting to BD25 BOB compared to screw terminals in ACORN?
I do not have it but if you say it is worth for some reason will do it.
Thanks

Continue with the header for now. See if you can get all your motors turning.

Most of these drives do better connected to the DB25
You will have to buy an inexpensive DB25 male breakout board. It makes it easy to connect.

Hi,

MPG integrated and it is up and running; it moves nicely axis 1 and 2.

Next step: bench test axis 3.

Afterwards I will pay attention to spindle integration with the investigation I did, to be sure to understand how the relay i/o board works.

Plan is to setup in wizard and bench test with multimeter measuring what will see my VFD spindle controller from 0-10 VDC port and i/o.

Thanks for all the help.

Lorenzo

Axis 3 working fine. All NPN NC inductive sensors working. Estop working. MPG working!

How you suggest to start setting up the spindle, and would it be possible to test on the bench before contecting to it?

Thanks!

Lorenzo

Don't know what spindle and spindle drive you have ...

Hello,
VFD of my machine is built in. Wiring details is in previous pages:
I checked that CW, CCW and RESET are sink to +24VDC for respective operation.
Signal 0-10 VDC controls spindle rpm (from 100 to 8000 rpm).
Considering my VFD pins and Acorn 0-10VDC port, Is following wiring OK?
Thanks!
Lorenzo
