Acorn and Accelus drive connections.

Post by RonRindahl »

I Have the same drives on an old Bridgeport I am starting to retrofit. Bought an Acorn over the weekend to replace the old motion controls from CNC Pro.

Old system jogged around fine, but not sure where I need to land the wires onto the Acorn when I receive it. I have attached a map of the pins that the original cable was using for control as far as where they landed on the Accelus drive, don't have documentation on the CNC Pro side.

In looking closer at the old system, the software if actually CNC Pro, in use on a Navigator II NC-PC Control made by Enhanced Automation.

I got some feedback on an old thread, but got directed to start a new thread. Am thinking I might need to re-configure the drive to interact with the Acorn board. But really not sure how to translate all the parameters.

Also attached the PDF of the drives cut sheet, not much more documentation than that available as far as I can find.

Thanks,
Ron

Do you have the software and cable for programming the drives? If so, we could probably help you find the correct options if you can post screenshots of the relevant menus and so on.

Have a cable on the way. Will try and connect an post some screen shots later this week.

Was reading through the CME User guide this morning. Looks like I can configure the I/O ports with multiple options (starts on page 52). Not clear to me what options to use. Attaching manual.

From the user guide you uploaded, I would set up the I/O like this:
*All used inputs set to pull up - that should include IN5 and IN6.
*All unused inputs should be set to "Not configured".
*IN2 is supposedly a dedicated Enable input so I would set IN2 as "Amp Enable-LO Enables With Clear Faults".
*OUT1 to "Fault Active Low" or "Fault Active High" depending on the wiring - more on this in a bit.

*I believe that setting the amplifier to position mode will make the correct function settings for IN5 and IN6. You'll want to follow the instructions on page 68 for that and set it to "Pulse and Direction" and 1 = 1 stepping resolution.


Since the outputs are open drain MOSFETs, it could be set up in a few different ways. Generally, I would recommend wiring all of the drive faults to a single Acorn input (DriveOK) and set IN1 as "Fault Active Low".
