Teknic Clearpath SDSK wiring to 7i96s

I mean connect all drives ENA+ lines to OUT0-
All drive ENA- lines to ground, and OUT0+ to +5V

This means when OUT0 is enabled, all drives are enabled
it really doesn't make sense to have per drive enables
as it wastes outputs and there is typically no operational
advantage with individual enables.

Thank you for everything so far.

I just looked at the 7i96s manual, and on page 10 I see that TB3 pin 13 is labeled "OUT0-", so I guess I was on the right track, sort of.

It's still not self-explanatory what you mean by OUT0+ to +5v, although you sort of partially explain it on page 14. Do you want me to connect my +5v power supply to TB3 pin 14? Doesn't that make it an input? Does every output (pins 13, 15, 17, 19) need its own power supply connection (pins 14, 16, 18, 20)?

You could avoid a lot of this back and forth by just publishing a typical use case wiring diagram. When I have this completely figured out, I am going to edit the top post, to accurately reflect the working system. Both for future me, and for others coming here to figure it out. That will hopefully also include all of the HAL changes, etc. I have seen other posts about Mesa boards and Clearpath SDSK, but they are sprawling conversations lacking a single definitive graphic at the top level that is accurate and well-labeled. I don't feel obligated to read the contents of the entire internet in order to hook up a servo motor.

I have heard great things about working LinuxCNC systems, but I have never heard a single positive experience from anyone setting one up.

Look out for an updated graphic. I'll be modifying the one above for the next hour or so, with my second cup of coffee.

The outputs are SSRs so act like relay contacts/switches
The do not supply power, they only switch it.

I get it now. Thanks!

This is the current state of my understanding of how to wire a Clearpath SDSK DC servo to a Mesa 7i962 board:

I have also modified the HLFB circuit, based on the graphic below, from page 51 of the Teknic Clearpath User Manual Rev. 3.23:

Please correct me if I have gotten anything wrong.

The above graphic assumes the +5-24VDC is not internal to the board, so... is it? Do I need to apply +5v somewhere to drive the HLFB circuit? Keep in mind, I have to add 6x NPN NC sensors, and the above would need to be compatible with that too.

I worked on it a bit more. It's missing 2x 24v NPN-NC probes, and I think with 24v common supplying the sensors and hlfb circuit, I may be able to daisy-chain the hlfb after all. Still confirmation there.

Hi fully_defined,

I'm an engineer with Teknic and came across your post. While we're not familiar with the exact board and pinout, the ClearPath wiring makes sense. (Good suggestions PCW)

If you encounter any problems or have other questions, please reach out directly at 585-784-7454 or teknic.com/contact/ .

Best regards,

Would you mind taking a second look? I have updated this post, and the image at the top reflects my current understanding of how to wire this. I think the only question relevant to you now is: now that I am powering the field inputs with 24v, can I get away with daisy chaining hlfb to save on inputs? I thought I recalled hearing that this is the preferred Teknic method, but I can't find anymore where I read that.

In this post, the OP said he figured it out and then the thread went cold. People had more questions that were unfortunately never addressed again: www.forum.linuxcnc.org/10-advanced-confi...fb-mesa-7i76e#114031

The purpose of this thread (the one you're reading now) is to create a definitive resource for myself and others to refer to later.
